The Mets, however, surrender the lead an inning later when right fielder Ryan Church misplays a fly ball that leads to an unearned run that is the deciding factor in the Padres' 6-5 victory. It is the second consecutive game lost in this manner by the Mets, as the previous day in Florida, left fielder Daniel Murphy committed an error that led to both runs in the Florida Marlins' 2-1 victory over the Mets.

- May 4 - The Los Angeles Dodgers beat the Arizona Diamondbacks 7-2 at Dodger Stadium, setting a National League record for the longest home win streak at the start of the season with eleven.

- May 6 - At Dodger Stadium, the Los Angeles Dodgers beat the Washington Nationals, 10-3, to set the modern Major League record for home wins to start the season, improving to 13-0 to surpass the 1911 Detroit Tigers. In 1880, the Chicago White Stockings won 21 in a row at home to start the season.

Instant replay shows that Victorino was actually the one who initiated contact with Reyes during the rundown play. The following batter, Jayson Werth, hits a two-run home run to bring the Phillies to within two runs of the Mets. The Mets hold on for a 7-5 victory. Manuel is suspended one game for the incident (May 9), and fined an undisclosed amount.
- At Fenway Park, twelve batters come up and all twelve score before the Boston Red Sox make their first out more than half an hour into the bottom of the sixth inning of a 13-3 win over the Cleveland Indians. The Red Sox break the American League record of 11 runs in an inning before making an out, set by the 1925 Detroit Tigers, who scored 11 runs in the sixth inning in a 19-1 win against the New York Yankees on June 17, 1925. Boston ties the modern major league mark of 12, set by the 1953 Brooklyn Dodgers on May 24, 1953, in the eighth inning of a 16-2 win at the Philadelphia Phillies, according to Elias Sports Bureau.

The lineup card shows Ben Zobrist and Evan Longoria both at third base (Longoria was supposed to be the designated hitter).

Gómez's record improves to 4-0 with an 0.31 ERA since moving up to Double-A Akron earlier in the season.
- Eighteen-year-old left-hander Jordan Wiener pitches a no-hitter for Robert F.

- May 22 - Michael Cuddyer hits for the cycle in the Minnesota Twins' 11-3 victory over the Milwaukee Brewers at the Hubert H. Humphrey Metrodome. Cuddyer joins Jason Kubel as the second Twin to hit for the cycle this season, and is the tenth in team history. The last teammates to hit for the cycle in the same season were Vladimir Guerrero and Brad Wilkerson of the 2003 Montreal Expos. Kubel's cycle came against the Los Angeles Angels on April 17 at the Metrodome.
- May 27 - With the Chicago Cubs up 2-1 over the Pittsburgh Pirates and a runner on third, Carlos Zambrano throws a pitch in the dirt to batter Nate McLouth. Nyjer Morgan, the runner on third, breaks for home. Catcher Geovany Soto flips the ball to Zambrano covering at the plate, but Morgan appears to sneak his left hand in, and is called safe by home plate umpire Mark Carlson. Zambrano disagrees with this call and argues with Carlson. During the argument, Zambrano and Carlson make contact, and Zambrano is ejected from the game. Zambrano goes off in a tirade that includes him ejecting Carlson, throwing the baseball in the air toward the outfield, slamming his glove on the ground and beating a Gatorade machine in the dugout with a baseball bat. The following day, he received a six-game suspension and an undisclosed fine for "inappropriate and violent actions on the field and in the dugout" from Major League Baseball vice president of on-field operations Bob Watson.

- June 2 - The 11-year-old son of Colorado Rockies catcher Yorvit Torrealba and two uncles, who were taking him to school, are kidnapped in Guarenas, Venezuela. The three are rescued the following evening when authorities posing as representatives of Torrealba paid a portion of the two million bolivares (about $931,000 U.S.) that the kidnappers had demanded in ransom. Upon receiving an undisclosed amount short of what they had sought, the culprits fled and left Torrealba's son and his two uncles on a highway in Araira. A police spokesman states afterward that six alleged kidnappers have been identified, but have not been captured.
- June 3 - In a surprise move, the Atlanta Braves release pitcher Tom Glavine. Since returning to the Braves, Glavine made only thirteen starts in 2008, and had yet to pitch at the major league level in 2009. The 305-game winner was on the verge of coming back from shoulder and elbow surgery. The previous night, in his third rehab start, Glavine threw six scoreless innings for the Class-A Rome Braves, and proclaimed himself ready to pitch in the majors again. Instead, the Braves called up top prospect Tommy Hanson to start that weekend against the Milwaukee Brewers. In another transaction, the Braves acquired All-Star center fielder Nate McLouth from the Pittsburgh Pirates for three prospects: outfielder Gorkys Hernández and pitchers Jeff Locke & Charlie Morton.

Teammates celebrate Buehrle's perfect game
- July 23 - At U. S. Cellular Field, the Chicago White Sox's Mark Buehrle pitches a 5-0 perfect game against the Tampa Bay Rays. DeWayne Wise, brought into the game in the ninth inning for defensive purposes, makes a spectacular catch to rob Gabe Kapler of what would have been a home run leading off the ninth. The perfect game is Buehrle's second career no-hitter and the second perfect game in White Sox history. Charlie Robertson pitched the first in 1922. Buehrle becomes the sixth pitcher to hurl both a perfect game and another no-hitter (which occurred in 2007), joining Cy Young, Addie Joss, Jim Bunning, Sandy Koufax and Randy Johnson. In the second inning, Josh Fields hits the first grand slam ever hit in a perfect game. Buehrle's 2007 no-hitter also featured a grand slam (Jermaine Dye). In addition, home plate umpire Eric Cooper also called balls and strikes for Buehrle's 2007 no-hitter; both Cooper and Buehrle wear number 56; and both no-hitters were completed in 2 hours, 3 minutes. Following the game, Buehrle receives a congratulatory call from President Obama.
- July 24 - The St. Louis Cardinals acquire Matt Holliday from the Oakland A's for minor leaguers Brett Wallace, Clayton Mortensen and Shane Peterson.
- July 27
- The Washington Nationals' Josh Willingham hits two grand slams in a game, the 13th player all-time to do so. His first slam is hit off Jeff Suppan and his second one comes off Mark DiFelice en route to a 14-6 Nationals victory over the Milwaukee Brewers.
- The New York Mets fire Vice President for player development Tony Bernazard. On July 21, the New York Daily News reported that at a recent game at Citi Field, Bernazard unleashed a profanity-laced tirade against a subordinate when the seat he wanted behind home plate was occupied by an Arizona Diamondbacks scout, and the subordinate suggested he wait until the half inning ended to take the seat. A day later, reports surfaced that Bernazard recently pulled off his shirt and challenged middle infield prospect Jose Coronado and the rest of the Mets' Double-A Binghamton Mets to a fight roughly ten days before the All-Star break. A recent 1-6 homestand and rumors of underage drinking by the team were the supposed catalysts of the tirade.
- July 28
- Two days after his enshrinement into the Baseball Hall of Fame, the Boston Red Sox retire Jim Rice's number 14.
- Mark Buehrle retires the first seventeen Minnesota Twins he faces. Factoring in the perfect game he pitched in his previous start and the final out he recorded in his July 18 start against the Baltimore Orioles, Buehrle retired 45 straight batters--a major league record. A walk to Alexi Casilla in the sixth inning ends his streak. The following batter, Denard Span, singles for the first hit, and Buehrle records just two more outs and gives up five earned runs as the Twins win 5-3. The previous record of 41 consecutive batters retired had been done twice. Jim Barr did it for the San Francisco Giants in 1972, and Bobby Jenks did it for the Chicago White Sox in 2007. The record-breaking 42nd out is of former teammate Joe Crede.
- July 29 - The Philadelphia Phillies acquire pitcher Cliff Lee and outfielder Ben Francisco from the Cleveland Indians for right-handers Jason Knapp and Carlos Carrasco, shortstop Jason Donald and catcher Lou Marson.

Boston acquired LaRoche from the Pittsburgh Pirates for Minor Leaguers Argenis Diaz and Hunter Strickland on July 22.
- Following an off-season filled with speculation that Jake Peavy would be traded to the Chicago Cubs, the San Diego Padres strike a 4-for-1 deal with the Cubs' cross-town rivals, the Chicago White Sox, for Peavy. The White Sox send left-handers Aaron Poreda and Clayton Richard and right-handers Dexter Carter and Adam Russell to San Diego for Peavy. The two clubs had struck a deal for Peavy on May 21 that reportedly also included Poreda and Richard, however, Peavy invoked his no-trade clause to block a potential trade.
- At the trade deadline, the Minnesota Twins acquire shortstop Orlando Cabrera from the Oakland A's for Minor League shortstop Tyler Ladendorf, the Detroit Tigers acquire pitcher Jarrod Washburn from the Seattle Mariners for left-handers Luke French and Mauricio Robles, the Cincinnati Reds received third baseman Scott Rolen and an undisclosed amount of cash from the Toronto Blue Jays for third baseman Edwin Encarnación, reliever Josh Roenicke and Minor League right-handed pitcher Zach Stewart, and the Florida Marlins acquire first baseman Nick Johnson from the Washington Nationals for lefty pitching prospect Aaron Thompson.

- August 4
- Bobby Abreu of the Los Angeles Angels is named the American League Player of the Month for July. The Angels' outfielder batted .380 during the month (27-for-89), driving in 28 runs and scoring a league-best 26 runs. His .467 on-base percentage also paced the AL. Abreu reached base in 25 of his 26 games in July, 13 of which were multi-hit and seven of which were multi-RBI. The monthly award is the second of Abreu's career, but his first in the AL, which he joined on July 30, 2006, when the Yankees acquired him from the Phillies.
- In the ninth inning of a 17-4 rout of the Milwaukee Brewers, the Los Angeles Dodgers' Guillermo Mota hits Prince Fielder in the leg with a pitch. Mota is immediately ejected by home plate umpire Lance Barksdale. After the game, Fielder charges down the dugout steps, and heads toward the Dodgers clubhouse yelling obscenities through a crowd of fans and reporters. Teammates Casey McGehee and Bill Hall and stadium security officials catch up with Fielder in time to usher him back to the visitor's side. Earlier in the game, the Dodgers' Juan Pierre and Manny Ramírez and the Brewers' Frank Catalanotto had also been hit by pitches.
- August 6
- Bobby Abreu leads off the fifth inning with a solo home run to left field, giving him 250 homers in his career and moving the Angels right fielder onto an impressive list of baseball achievers. Abreu becomes one of only six players in major league history to collect 250 home runs, 2,000 hits, 1,000 runs, 1,000 runs batted in, 1,000 walks and 300 stolen bases. The others are Barry Bonds, Craig Biggio, and Hall of Famers Joe Morgan, Rickey Henderson and Willie Mays.
- On consecutive pitches, New York Yankees rookie Mark Melancon fires one heater over Dustin Pedroia's head and to the backstop, and a second into Pedroia's left shoulder during New York's 13-6 victory over the Boston Red Sox.

- August 7
- Rookie Everth Cabrera hits a walk-off grand slam in the ninth inning off closer Francisco Rodríguez to give the San Diego Padres a 6-2 victory over the New York Mets.
- In different transactions, the Boston Red Sox designate John Smoltz for assignment, the Oakland Athletics give Jason Giambi his unconditional release, and the Minnesota Twins acquire right-hander Carl Pavano from the Cleveland Indians for a player to be named later.

- August 10
- August 11 - Junichi Tazawa gives up three runs (one earned) while striking out six in five innings as the Boston Red Sox beat the Detroit Tigers, 7-5, at Fenway Park. Tazawa, at 23 years of age, becomes the youngest Japanese-born pitcher to win his first major league start. Early in the game, Kevin Youkilis is hit by a pitch by Tigers hurler Rick Porcello. Players from benches and bullpens went onto the field and Youkilis tackled Porcello, but no punches are thrown. Youkilis and Porcello are ejected and later suspended five games each.
- August 12 - Pedro Martínez wins his first start with the Philadelphia Phillies, giving up three earned runs over five innings in a 12-5 victory over the Chicago Cubs at Wrigley Field.

- The Los Angeles Angels score nine runs in the 13th inning of their 17-8 victory over the Baltimore Orioles. The Major League record for runs in any extra inning is 12, set by the Texas Rangers against the A's in Oakland on July 3, 1983.
- August 17
- The Detroit Tigers acquire 1B/DH Aubrey Huff from the Baltimore Orioles in exchange for minor league pitcher Brett Jacobson.
- Garrett Jones, who homered in Pittsburgh's 9-5 victory over Milwaukee, has, as of this date, hit 13 home runs in only 40 games this season. Jones is the first rookie in eight years to hit 13 (or more) home runs in his first 40 games of a season, joining Albert Pujols and Adam Dunn, who did that in 2001.
- August 18 - The Angels defeated the Indians, 5-4, at Cleveland. Each of the nine players in the Angels' batting order comes out of this game with a season's batting average of .300 or higher. It's the first time since 1934 that any major league team has finished a game-at least 100 games into a season-with each player in its starting batting order hitting .300 or better. The lineups: 2009 Angels Chone Figgins, 3b .308, Bobby Abreu, rf .310, Juan Rivera, lf .310, Vladimir Guerrero, dh .313, Kendrys Morales, 1b .303, Torii Hunter, cf .307, Maicer Izturis, 2b .300, Mike Napoli, c .300, Erick Aybar, ss .313. 1934 Tigers (September 9, 1934, 5-4 win vs. Red Sox) Jo-Jo White, cf .307, Mickey Cochrane, c .328, Charlie Gehringer, 2b .364, Goose Goslin, lf .306, Billy Rogell, ss .303, Hank Greenberg, 1b .337, Marv Owen, 3b .322, Gee Walker, rf .301, Schoolboy Rowe, p .302.
- August 19 - Following a rain delay, Jamie Moyer pitches six scoreless innings in relief of Pedro Martínez, who had taken his spot in the starting rotation, and the Philadelphia Phillies beat the Arizona Diamondbacks 5-1. Chase Utley's 25th home run of the season is the first in a four-homer barrage unleashed by the Phillies, as he becomes the fourth player to reach the 25-homer plateau for Philadelphia this season, joining Ryan Howard, Raúl Ibañez and Jayson Werth. In National League history, only one other team had as many as four players each hit 25 or more home runs as early in a season as this year's Phillies (through their first 117 games). That was the 1995 Colorado Rockies, with Dante Bichette, Vinny Castilla, Andrés Galarraga and Larry Walker all reaching that mark through the team's first 105 games.
- August 20
- Limited to four hits in a 4-1 loss to the Houston Astros, the Florida Marlins' impressive string of consecutive games with at least 10 hits comes to an end. The streak, which began on August 4 at Washington, reached 15 games, marking the first time since the 1937 St. Louis Browns reach that mark. Florida's streak was the longest by a National League team since the 1929 New York Giants did it. Only three teams since 1900 had streaks longer than 15: the 1925 Cleveland Indians and 1922 St. Louis Browns each reached 18, while the 1900 Philadelphia Phillies finished at 16.
- Red Sox catcher/first baseman Víctor Martínez hits his 20th home run of the season in an 8-1 victory against the Blue Jays, becoming the fourth American League player to hit 20 homers in a season while playing at least 50 games at both catcher and first base. Martínez joins Gene Tenace (1974-'76), Mickey Tettleton (1993) and Gus Triandos (1956).
- August 21
- The Yankees beat the Red Sox, 20-11, in the highest-scoring game in the history of their rivalry. The Yankees' 20 runs were the third-most they have ever scored against Boston, behind a 24-4 win in 1923 and a 22-1 victory in 2000.
- Garrett Jones hits his 14th home run of the season in Pittsburgh's win against Cincinnati. Jones, who played his first game this season on July 1, ties the Pirates rookie record for most home runs hit over consecutive calendar months. That record had been untouched for 51 years, since Dick Stuart hit 14 home runs spanning July and August 1958.
- August 23
- In the ninth inning of a 9-7 victory over the New York Mets at Citi Field, second baseman Eric Bruntlett of the Philadelphia Phillies turns the 15th unassisted triple play in Major League history. He catches Jeff Francoeur's line drive for the first out, doubles Luis Castillo off second and tags out Daniel Murphy for the final out. Bruntlett's feat was only the second unassisted triple play to end a game, Johnny Neun having turned the other, on May 31, 1927. It is also only the second unassisted triple play turned by a second baseman in National League play, Mickey Morandini having turned the other, on September 20, 1992.
- Miguel Cabrera of the Detroit Tigers hits his 200th career home run in a 9-4 defeat to the Oakland Athletics, becoming the fifth Venezuelan player to reach that plateau. Cabrera joins fellow countrymen Tony Armas (251), Bobby Abreu (252), Magglio Ordóñez (275) and Andrés Galarraga (399) on that list. The homer was his team-leading 25th of the season, marking the sixth consecutive season he has reached that total.
- The Minnesota Twins' Michael Cuddyer hits two home runs in the seventh inning against Kansas City. With his hitting for the cycle on May 22, he is the first player ever to accomplish that feat and a two-homer inning in the same baseball season.
- August 24
- Cliff Lee allows only two unearned runs in seven innings at Citi Field, improving to 5-0 with a 0.68 ERA since joining the Phillies. Lee and Fernando Valenzuela are the only major-league pitchers in the past 60 years to win each of their first five career starts for a team, with an ERA below 1.00 over those five games. Through five starts in 1981, Valenzuela's ERA was 0.20.
- Ryan Howard's first-inning home run at Citi Field produces his 600th career RBI. Howard reaches that milestone in his 693rd game, the fastest for any major-league player since 1946, when Ted Williams collected his 600th RBI in his 675th game.
- Ryan Spilborghs' grand slam in the bottom of the 14th inning gives the Colorado Rockies a 6-4 win over the San Francisco Giants. Since 1900, only one player hit a walk-off grand slam in a later inning: Clyde Vollmer of the Boston Red Sox hit a grand slam in the bottom of the 16th inning to beat the Indians at Fenway Park (July 28, 1951).
- August 25
- Four days after being claimed on waivers by the Boston Red Sox, Billy Wagner is dealt by the New York Mets to Boston for two players to be named later. Wagner had just returned to the Mets from Tommy John surgery that cut short his 2008 season, and had only made two appearances in 2009.
- Zack Greinke sets a team record with 15 strikeouts over eight innings in the Kansas City Royals' 6-2 win over the Cleveland Indians.
- August 28 - The Los Angeles Angels acquire left-hander Scott Kazmir from the Tampa Bay Rays for prospects Alexander Torres, Matthew Sweeney and a player to be named later. Second baseman Sean Rodriguez is sent to the Rays on September 1 to complete the deal.
- September 3 - Kendrys Morales of the Anaheim Angels is named the American League Player of the Month for August, after he hit .385 (42-for-109) with 10 home runs, eight doubles, 22 runs, and 33 RBI in 28 games. Morales also set a new club record for RBI in the month, previously held by Bobby Bonds (31, 1977) and was one RBI shy of the franchise record for any month. Last month, Angels' outfielder Bobby Abreu was selected as the A.L. Player of the Month for July. This is the first time any major league club has had consecutive monthly award winners since Texas Rangers' outfielder Josh Hamilton won in both April and May of 2008.
- September 6 - Ichiro Suzuki becomes the second-fastest player in Major League history to reach 2,000 hits with a first-inning double in his 1,402nd game (2001-present). Al Simmons did it in 1,390 games (1924-1934).
- September 7
- At PNC Park, the Chicago Cubs assure the Pittsburgh Pirates of a record-breaking 17th consecutive losing season, getting two home runs from Derrek Lee and a solid start from pitcher Ted Lilly while winning 4-2. The Pirates will finish below a .500 average, just as they have every season since 1993. The losing string is a major league record and the longest for any team in the four major North American professional team sports.
- Chris Carpenter of the St. Louis Cardinals tosses a one-hit shutout with 10 strikeouts against the Milwaukee Brewers, 3-0. Carpenter also threw a one-hitter shutout with 10 strikeouts for St. Louis in 2005 (Blue Jays). Since 1900, only two other Cardinals pitchers had a shutout in which they struck out at least 10 batters and did not allow more than one hit: Bob Gibson in 1970 (Padres) and 1971 (Pirates, no-hitter) and Ernie Broglio in 1960 (Cubs).
- Mark Buehrle and the Chicago White Sox beat the Boston Red Sox 5-1. It is Buehrle's first victory since his perfect game on July 23. Since then, he had been 0-4 with a 5.44 ERA before this win.
- September 8
- Raúl Ibañez belts two home runs while Jayson Werth, Carlos Ruíz and Chase Utley each add one apiece, to help the Philadelphia Phillies and Pedro Martínez to a 5-3 victory over the Washington Nationals. Ibáñez and Utley both reached their 30th HR of the season, joining Werth (32) and Ryan Howard (38), making the Phillies the 12th team in MLB history with four 30-HR players and only the second with three left-handed batters to reach 30 homers (Howard, Ibáñez and Utley). The first was the 1929 Phillies trio of Lefty O'Doul, Don Hurst and Chuck Klein. The other 11 teams with four 30-HR players in a season are the 1977 Dodgers, 1995 Rockies, 1996 Rockies, 1997 Dodgers, 1997 Rockies, 1998 Braves, 1999 Rockies, 2000 Blue Jays, 2000 Angels, 2004 Chicago Cubs and 2006 White Sox.
- The Chicago Cubs tie a major league record with eight consecutive hits to start a game in a 9-4 win against the Pittsburgh Pirates. The Cubs also accomplished this feat in 1973 (both against Pittsburgh). Only four other teams had eight straight hits to start a game: 1975 Phillies, 1975 Pirates, 1981 Athletics and 1990 Yankees.
Derek Jeter became the Yankees' all-time hit leader September 11, 2009
- September 9
- Brian Roberts of the Baltimore Orioles becomes just the fourth player in major league history to have three seasons with at least 50 doubles (2004, 2008-'09). The other players to reach 50 or more doubles at least three times were Hall of Famers Tris Speaker (1912, 1920-'21, 1923), Paul Waner (1928, 1932, 1936) and Stan Musial (1944, 1946, 1953). Roberts also set the all-time record for second basemen with his three 50-double seasons. HoF Billy Herman (1935-'36) and Houston Astros' Craig Biggio (1998-'99) both collected 50-plus doubles in back-to-back seasons but never came close to matching it again.
- Scott Feldman earns his club-record 12th road win of the season as the Texas Rangers defeated the Cleveland Indians, 10-0, at Progressive Field. Feldman's eight successive road wins is the longest such streak in club history.
- Derek Jeter collects three hits against the Tampa Bay Rays to give him 2,721 for his Yankee career, tying him with Lou Gehrig atop the Yankees' all-time hits list.
- September 10 - Ian Desmond hits a home run and drives in four runs in his major league debut to lead the Washington Nationals to an 8-7 victory over the Philadelphia Phillies. Desmond is only the second player since 1920 (the first season run batted in was recorded as an official statistic) to drive in at least four runs as a shortstop in his major league debut. The other player to do it was Ted Kazanski for the Phillies against the Cubs on June 25, 1953. Matt Stairs of the Phillies belts the second pinch-hit grand slam of his career in a lost cause.
- September 11 - With a single off Chris Tillman to lead off the third inning, Derek Jeter collects his 2,722nd career hit to pass Lou Gehrig as the all-time Yankees hit leader.
- September 13 - In the second inning of the second game of a doubleheader against the Texas Rangers, Ichiro Suzuki hits a slow grounder to Rangers shortstop Elvis Andrus that he legs out for a single. It is his 200th hit of the season, giving him a MLB record nine consecutive 200 hit seasons.
- September 15
- In the eighth inning of the Toronto Blue Jays' 10-4 victory over the New York Yankees at Yankee Stadium, a bench-clearing brawl breaks out. Earlier in the game Blue Jays third baseman Edwin Encarnación is hit by a Sergio Mitre pitch, and in the eighth inning second baseman Aaron Hill is hit by Mark Melancon. In what appeared to be retaliation for the shot to Hill, Jays pitcher Jesse Carlson throws a pitch behind Yankees catcher Jorge Posada in the bottom half of the inning. Both benches and bullpens clear; however, no punches are thrown. Posada ends up reaching on a walk, and scores on a Brett Gardner double. As he crosses the plate, he bumps Carlson, who had been backing up home plate on the play. Posada is immediately ejected from the game, and the benches and bullpens empty for a second time as a fight breaks out between the two.
- Daisuke Matsuzaka of the Boston Red Sox is activated following his near three-month stint on the disabled list, to become the fourth Japanese player on Boston's active roster, setting a Major League record. Matsuzaka joins fellow pitchers Takashi Saito, Hideki Okajima and Junichi Tazawa. On August 7, in a 15-inning loss at Yankee Stadium, the Red Sox had set another record, becoming the first team to deploy three Japanese pitchers in the same game.
- September 16 - Jayson Werth's seventh-inning grand slam is the key hit in Philadelphia's 6-1 win against Washington, the Phillies' major-league leading tenth slam this season, making them only the sixth team in National League history to hit at least 10 slams in one season. Meanwhile, Ian Desmond goes 2-for-4 against the Phillies and is now 10-for-17 (.588) since making his major-league debut, to become the first major league player in more than half a century to collect 10 hits over his first four career games. The last player to do that was Jim Davenport for the 1958 Giants, in the team's first season in San Francisco.
- September 18 - With two outs in the ninth inning, and Mariano Rivera on the mound for the Yankees, Mike Sweeney hits a double, followed by a first-pitch home run by Ichiro Suzuki to give the Mariners a 3-2 victory. It is the first walk-off home run of Ichiro's career.
- September 20 - Chicago Cubs general manager Jim Hendry suspends outfielder Milton Bradley for the final two weeks of the 2009 season following comments he made in which he said the Cubs were "not a positive environment." Hendry explained the decision with the following:
||There have been a lot of issues that we've lived with during the year, but the last few days became too much for me to tolerate, to be honest with you. I'm not going to let our great fans become an excuse, I'm not going to tolerate not answering questions from the media respectfully. Whether you feel like talking or not, it's part of our jobs. I'm not going to allow disrespect to other people in that locker room and uniformed personnel. The only real negativity here is his own production.
- Three days later, Bradley would issue an apology.
- September 21 - Cecil Cooper is fired as manager of the Houston Astros. Third-base coach Dave Clark is named interim manager for the thirteen games remaining in their season.
- September 22
- Dan Uggla of the Florida Marlins hits his 30th home run of the season in the second game of a doubleheader against the Philadelphia Phillies, giving Uggla three consecutive seasons of 30-or-more homers. He is the first player in major league history to do so while playing at least 100 games at second base. Ryne Sandberg (1989-1990), Alfonso Soriano (2002-2003) and Chase Utley (2008-2009) are the only other second basemen with 30-HRs in 100 games during two straight seasons.
- Mark Reynolds of the Arizona Diamondbacks strikes out three times for a total of 206 on the season, breaking the single-season record of 204 that he set in 2008.

Cardinals first baseman Albert Pujols is named the MLB Athlete of the Decade, ex-Yankees manager Joe Torre, now managing the Dodgers, is named Manager of the Decade, and the Red Sox are named the Team of the Decade.
- September 25 - Ian Kinsler's three-run home run in the Texas Rangers' 8-3 victory over the visiting Tampa Bay Rays is his 30th home run of the season. Combined with his 30th stolen base a day before, he becomes only the second player in Rangers' history to put up a 30-HR 30-SB season, joining Alfonso Soriano, who did it in 2005. Kinsler also joins Soriano, who also had 30-30 seasons for the Yankees (2002-2003), and Brandon Phillips of the Reds (2007) as the only 30/30 second basemen in Major League history.
- September 26
- Ichiro Suzuki is ejected for the first time in his professional career, ending a streak that Suzuki started in 1992 as a rookie with the Japan's Orix BlueWave. It happens in the top of the fifth inning of the Mariners' eventual extra-inning 5-4 loss to the Blue Jays at Rogers Centre, and is also the first ejection of a Mariners player, coach or manager this season.
- Marlon Byrd of the Texas Rangers hits his sixth career grand slam in the 15-3 victory against the visiting Tampa Bay Rays. Byrd, who homered twice in the game, now has 59 lifetime home runs, becoming the only player in major-league history with fewer than 60 home runs and six-or-more grand slams.
- The St. Louis Cardinals clinch the National League Central Division title with a 6-3 victory over the Colorado Rockies. It is the eighth division title for the Cardinals manager Tony La Russa in his 14-year tenure in St. Louis.
- Víctor Martínez of the Boston Red Sox singles with two outs in the ninth off Mariano Rivera, extending his hitting streak to 25 games, in a 3-0 defeat against New York at Yankee Stadium. Martinez's streak is the longest by a Venezuelan-born player, surpassing the 59-year, 24-game streak set by Chico Carrasquel in 1950. Martínez's streak ends the following day, but he bats 34-for-95 (.358) during the streak.
- Team Canada earns its first bronze medal in the 2009 Baseball World Cup by upending Puerto Rico, 6-2, in Grosseto, Italy. The third-place finish is the senior national team's highest placing since earning a bronze medal at the 1999 Pan American Games in Winnipeg, Canada. The medal also adds to Baseball Canada's total which is now 11 with two bronze and a silver for the women's national team and five bronze and one gold (1991 world junior) for the national junior team.
- September 27
- The New York Yankees secure their 16th AL division crown since 1969 (11th since 1995) with a 4-2 win over their arch-rivals, the Boston Red Sox. The Yankees put a bow on this title with their major-league leading 100th win, as second baseman Robinson Canó collected his 200th hit of the season. Canó's infield partner, shortstop Derek Jeter, already has 200 hits in the season, becoming the first second baseman/shortstop combo to accomplish the feat in major league history.
- Team USA takes advantage of a critical error by Cuba, scoring six runs with two outs in the seventh inning on its way to a 10-5 win in the gold medal game of the 2009 Baseball World Cup in Nettuno, Italy. Paired with its win over Cuba in the 2007 tournament, the Americans have won back-to-back World Cup titles for the first time since 1973 and 1974. Justin Smoak, Terry Tiffee and Jon Weber are named to the IBAF World Cup All-Tournament Team. Smoak is also named the Baseball World Cup's Most Valuable Player.
- In the eighth inning of the Cardinals' 4-3 loss to the Rockies in Coors Field, Albert Pujols records his 181st assist of the season, setting a National League record for most assists in a season by a first baseman. The previous record had been set by the Cubs' Mark Grace in 1990. Bill Buckner holds the Major League record of 184, set in 1985 with the Red Sox.
- September 28
- The Los Angeles Angels defeat the Texas Rangers convincingly, 11-0, to take the American League West title. Los Angeles is headed back to the playoffs for the sixth time in eight years.
- Carlos Lee of the Houston Astros drives in his 100th run of the season, giving him a five-year streak of reaching triple-digits in RBIs. Only four other players have driven in at least 100 runs in each of the last five seasons: Bobby Abreu, Miguel Cabrera, Albert Pujols and Mark Teixeira.
- Robinson Canó hits his 25th home run of the season, and he now has 201 hits as a second baseman this year. Since Rogers Hornsby retired in 1937, only two other players have had 200 hits and 25 homers as a second baseman in one season: Bret Boone in 2001 and Alfonso Soriano in 2002. Over the last 70 years only three other Yankees players have had a 200-hit, 25-HR season: Don Mattingly (1985-1986), Bernie Williams (1999) and Soriano (2002).
- September 29
- The Baltimore Orioles' Brian Roberts hits his 56th double this season against Tampa Bay's Wade Davis, breaking the record for a switch-hitter set by Lance Berkman in 2001. Earlier in the season, Roberts became just the fourth player all-time to record three 50-double seasons, the other three being Stan Musial, Tris Speaker and Paul Waner.
- After being down 8-2 to the Toronto Blue Jays, the Boston Red Sox score five in the eighth to bring it within one run. Although their comeback attempt falls short, a 5-2 loss by the Texas Rangers to the Los Angeles Angels secures the Wild Card for the BoSox. Adam Lind has a memorable game, hitting three home runs for the Blue Jays.
- September 30
- Cleveland Indians General Manager Mark Shapiro announces that Eric Wedge and his coaches have all been relieved of their duties. However, Wedge and his staff will stay aboard for the season's final six games.
- The Philadelphia Phillies clinch their third straight NL East title, 10-3 at home against the Houston Astros.
- Ricky Nolasco of the Florida Marlins sets a club record with 16 strikeouts and came within one of a Major League mark by fanning nine straight in a 5-4 victory over the Atlanta Braves. The big league record for consecutive strikeouts in a game is 10 by Tom Seaver for the New York Mets on April 22, 1970. Two other pitchers had nine consecutive strikeouts in one game: Mickey Welch for the New York Giants in 1884 and Jake Peavy for the San Diego Padres in 2007.
- Pirates catcher Ryan Doumit goes 4-for-4 with a home run and four RBIs in the second game of a double-header against the Cubs. Doumit is only the second Pittsburgh catcher in the last 40 years to have at least four hits and four RBIs in the same game. Jason Kendall collected four hits and five RBIs in a 13-1 Pirates victory over the Cardinals on May 19, 2000.
- Justin Maxwell of the Washington Nationals becomes the second player (and the second rookie) to hit a walk-off grand slam against New York Mets closer Francisco Rodríguez this season. Everth Cabrera of the San Diego Padres did that on August 7. The only other pitchers in major-league history to surrender two game-ending grand slams in one season were Satchel Paige (1952), Lindy McDaniel (1963) and Lee Smith (1995).
- Justin Masterson goes the distance for the Cleveland Indians and struck out 12 but the Chicago White Sox scratch out a run in the top of the sixth inning to win 1-0. Masterson is the first major-leaguer to lose a complete game by a 1-0 score while pitching at least nine innings and striking out a dozen or more batters since May 6, 2000, when Pedro Martínez of the Red Sox struck out 17 but was beaten by Tampa Bay at Fenway Park.
- October 1:
- Ichiro Suzuki of the Seattle Mariners collects his 220 hit of season to set a new Major League mark. It is the fifth time in nine seasons in the majors that Suzuki has reached 220 hits, supplanting the old record of four 220-hit seasons shared by Hall of Famers Jesse Burkett and Rogers Hornsby. Earlier this season, Suzuki surpassed another Hall of Famer when he collected his ninth consecutive 200-hit season (September 13), breaking the long-standing major-league record of eight straight 200-hit seasons set by Wee Willie Keeler from 1894 to 1901.
- Orlando Cabrera hits his first career grand slam to lead the Twins to an 8-3 win over Detroit. Cabrera, who had never hit a home run in 135 previous at-bats with the bases loaded, was the only active major leaguer who has had at least 100 bases-loaded at-bats without a grand slam to his credit.
- Tony La Russa passes John McGraw for second-most games managed in baseball with his 4,770th game managed (2,552-2,214-4). La Russa gets three more games (October 4) to extend his managed games to 4,773 (2,552-2,217-4) by the end of the 2009 season.
- October 2:
- B. J. Upton not only hits for the cycle in the Rays' 13-4 victory over the Yankees, but he does it by the end of the fifth inning. It is the quickest cycle since Mike Lansing of the Rockies accumulated all four hits within the first four innings against the Diamondbacks on June 18, 2000. The Rays score nine runs in the first three innings to deny CC Sabathia his first 20-win season. Sabathia is the first pitcher in nearly 30 years to allow as many as nine runs in a game while needing one more victory for the first 20-win season of his career. The last pitcher to do so was Rick Langford of the Athletics in 1980.
- Adam Wainwright of the Cardinals also fails to earn his 20th victory when the Brewers rally for six runs in the seventh inning of their eventual 12-6 win. 2009 will be only the second season in major-league history without a 20-game winner (see 2006), excluding seasons that were shortened by work stoppages.
- October 3:
- In the early morning hours, following an 0-4 performance in an 8-0 loss to the Chicago White Sox the previous night, Miguel Cabrera is picked up by Birmingham, Michigan police after a 911 call from his wife, Rosangel. The couple began fighting when Miguel came home intoxicated talking on the phone, and woke up their child. When police arrive at his suburban Detroit home at 5:00 AM, Cabrera blows a 0.26 on the breathalyzer administered on the scene, which is three times Michigan's legal limit for driving. Tigers GM Dave Dombrowski picks him up at the station at roughly 7:30 AM. That evening, Cabrera goes 0-4 and strands six runners in the Tigers' 5-1 loss to the ChiSox.
- The San Diego Padres announce that executive vice president/general manager Kevin Towers will not return for the 2010 season. In a similar movement, the Toronto Blue Jays dismissed general manager J. P. Ricciardi after eight seasons.
- Ryan Howard is in select company after hitting his 45th home run of the season in Philadelphia's loss to Florida. The 29-year-old Howard is only the second player to do that before his 30th birthday, the other being Harmon Killebrew (1961 to 1964, at 28). Beside this, as Howard nears the end of his fifth full season he has a career total of 640 runs batted in, moving past for the third-highest RBI total after five seasons in Major League history over Lou Gehrig (639, 1926-'30) and Ted Williams (638, 1939-'42, 1946). The leader and runner-up are Joe DiMaggio (691, 1936-'40) and Hal Trosky (663, 1934-'38).
- October 4:
- Alex Rodriguez belts a three-run homer and a grand slam in New York's 10-run 6th inning, leading the Yankees to a 10-2 victory over the Rays in the regular-season finale. Rodriguez' 30th home run of the season makes him the first AL player to have 7 RBIs in a single inning. The only other Major Leaguers to have 7 or more RBIs in an inning are Fernando Tatís, who hit two grand slams as a member of the Cardinals to collect 8 RBIs against the Dodgers in the third inning on April 23, 1999, and Ed Cartwright, who hit a 3-run homer and a grand slam in the 3rd inning on September 23, 1890, for 7 RBIs. Rodriguez also reached the 30 HR/100 RBI plateau for the 12th consecutive season.
- Albert Pujols breaks Bill Buckner's 1985 major-league record for assists by a first baseman, with his 185th.
- The Detroit Tigers and Minnesota Twins each win their final (162nd) games, leading to a one-game tiebreaker at the Metrodome to decide the American League Central champion. It is the third consecutive season - the longest such streak in MLB history - that the regular season goes beyond 162 games, requiring a division tiebreaker to finalize the postseason field. The Twins become the first club ever to play such a tiebreaker in consecutive years, having lost the AL Central tiebreaker against the Chicago White Sox in 2008. The Colorado Rockies beat the San Diego Padres for the 2007 National League Wild Card to start this three-year extension.
- Mark Reynolds of the Arizona Diamondbacks strikes out three times, setting a new season record of 223 strikeouts in a season.
- October 5 - The Milwaukee Brewers and Trevor Hoffman agree to a one-year deal with a mutual option for 2011.
- October 6:
- Kansas City Royals first baseman Billy Butler is named winner of the AL Player of the Month Award for September. Butler batted .363 in the month with 10 doubles, six home runs and 26 RBI. He also recorded his fourth 3-double game of the season on September 9 against the Detroit Tigers to set a Major League record and had a pair of 2-homer games against the Los Angeles Angels (September 7) and Minnesota Twins (September 25). His 26 RBIs in the month led the AL and were tied for second in baseball. Butler and Zack Greinke (April) are the first Royals duo to win the award in the same season since 2000, when Jermaine Dye and Johnny Damon took home the honor.
- Chicago Cubs first baseman Derrek Lee is named winner of the NL Player of the Month Award for September, after he led the Majors with a .386 average (32-for-83) with nine home runs, 23 RBIs, a .795 slugging percentage and .500 on-base percentage.
- The final regular season game in the Metrodome may have been the best. The one-game division playoff between the Minnesota Twins and Detroit Tigers goes extra innings, 4-4. Both teams score a run in the tenth before an Alexi Casilla single in the twelfth inning scores Carlos Gómez from second to give the Twins the 6-5 victory. They become the first team in Major League history to win the division after trailing by three games with four to play. They are also the first team in MLB history to make the playoffs in the final year of their stadium.
2009 is Joe Torre's record tying 14th consecutive post season
- October 7:
- The Philadelphia Phillies open defense of their World Series title with a convincing victory over the Colorado Rockies, 5-1, in Game 1 of the NLDS behind a dominant Cliff Lee in his postseason debut. Lee hurls a complete game and gets support from Raúl Ibañez, Jayson Werth and Ryan Howard RBI extra-base hits. Rockies starter Ubaldo Jiménez matches Lee with four scoreless innings before surrendering two runs in the fifth inning and three in the sixth.
- The New York Yankees win their first playoff game at new Yankee Stadium, as CC Sabathia holds down the Minnesota Twins, 7-2, in Game 1 of the ALDS. Derek Jeter and Hideki Matsui homer, and Alex Rodriguez contribute with two RBIs. Minnesota scores first, but rookie left-hander Brian Duensing gives it all back and the Twins cannot recover.
- The Los Angeles Dodgers defeat Chris Carpenter and the St. Louis Cardinals, 5-3, in Game 1 of the NLDS. After St. Louis scores a run off Randy Wolf in the first inning, Matt Kemp blasts a two-run homer in the bottom half of the frame, and Los Angeles does not trail again. Carpenter allows four runs in an uneven five-inning performance. Rafael Furcal goes 3-for-4, as the Dodgers' bullpen gives up a run in 5 superb innings. The Dodgers (16) and Cardinals (14) combine to strand 30 runners on base, setting a record for a nine-inning postseason game.
- October 8:
- The Colorado Rockies even the NLDS against the Philadelphia Phillies, winning the second game, 5-4, at Citizens Bank Park. Aaron Cook combines with five relievers for the victory, while the attack is led by Yorvit Torrealba (2-for-3, two-run homer) and Carlos González (3-for-5, run). Cole Hamels is the losing pitcher.
- The Los Angeles Dodgers take advantage of a crucial error by Matt Holliday with two outs, bases empty in the bottom of the ninth inning, to defeat the St. Louis Cardinals 3-2. Ronnie Belliard and Mark Loretta come through with RBI singles off closer Ryan Franklin, giving the Dodgers a 2-0 lead in the NLDS. St. Louis starter Adam Wainwright, who lasts eight innings, allows one run on three hits and strikes out seven in a lost cause.
- The Los Angeles Angels defeat the Boston Red Sox in the ALDS opener, 5-0, behind a strong start by John Lackey, who allows four hits in 7 innings of work. Torii Hunter gets the game-breaking hit, a three-run homer off Jon Lester in the bottom of the fifth inning that breaks a scoreless tie, and reliever Darren Oliver pitches 1 innings of no-hit ball.
- October 9:
- The New York Yankees storm past the Minnesota Twins in Game 2 of their division series, tying it in the ninth inning on a two-run homer by Alex Rodriguez and winning in the 11th, 4-3, on a blast down the left-field line by Mark Teixeira.
- The Los Angeles Angels manufacture a three-run seventh inning to move one win away from the ALCS and leave the Boston Red Sox on the precipice. Jered Weaver pitches brilliantly in his second career postseason start, outduelling Josh Beckett in the 4-1 triumph.
- October 10 - The Los Angeles Dodgers dispose of the host St. Louis Cardinals in Game 3 of the NLDS, 5-1, advancing to the league championship. For Joe Torre, it is his sixth postseason series sweep as a Major League manager. Torre had four sweeps with the Yankees (1998 ALDS vs. Texas and World Series vs. San Diego, and 1999 ALDS vs. Texas and World Series vs. Atlanta) and one previous sweep with the Dodgers (2008 NLDS vs. Cubs). The only other manager in Major League history to lead his teams to at least six postseason series sweeps is the manager Torre defeated in this year's NLDS, Tony La Russa, who has seven sweeps on his resume.
- October 11:
- The Los Angeles Angels comes up with a three-run comeback in the ninth inning off Jonathan Papelbon, to clinch the ALDS with a 7-6 victory against the Boston Red Sox at Fenway Park. Vladimir Guerrero brings home the tying and winning runs with a single and the Angels sweep aside the Red Sox in stunning fashion.
- The New York Yankees defeat the Minnesota Twins, 4-1, to complete a three-game sweep of their ALDS and record their first victory in a postseason series since 2004, thanks to Andy Pettitte, who pitches a gem, and home runs from Alex Rodriguez and Jorge Posada. It is the final baseball game inside the Hubert H. Humphrey Metrodome, which will be replaced next season by Minneapolis' Target Field.
- October 12 - The Philadelphia Phillies are headed back to the NLCS after eliminating the Colorado Rockies from the playoffs with a three-run, ninth-inning rally, in Game 4 of the NLDS. The defending World Series Champions blow a one-run lead in the bottom of the eighth inning before pulling out a 5-4 victory at Coors Field. The Phillies-Rockies series is the only one in the first round not to end in a three-game sweep. The 13 combined games during the opening round equal the fewest (in 2007) since the three-round postseason format was introduced in 1995.
- October 14 - For the third time of his career, New York Yankees closer Mariano Rivera earns the MLB Delivery Man of the Year Award, sponsored by DHL. Rivera went 3-3 with a 1.76 ERA in innings of work and converted 44 of his 46 save opportunities (95.7%), permitting 48 hits and 12 walks with 72 strikeouts while holding opposing hitters to a .197 batting average.
- October 15 - Carlos Ruiz and Raúl Ibañez hit three-run homers, Cole Hamels wins his fourth Game 1 of the postseason, and closer Brad Lidge finishes off the Philadelphia Phillies' 8-6 victory over the Los Angeles Dodgers in the NLCS opener at Dodger Stadium.
- October 16:
- The Los Angeles Dodgers defeat the Philadelphia Phillies, 2-1, in Game 2 of the NLCS. Ryan Howard hits a solo homer in the fourth inning to put the Phillies ahead, but an eighth-inning bullpen collapse combined with a crucial error by Chase Utley and a bases-loaded, walk-RBI to Andre Ethier makes the difference. Phillies' Pedro Martínez and Dodgers' Vicente Padilla find themselves in a pitching duel during seven-plus innings, but they are not a factor in the decision. Hong-Chih Kuo is the winning pitcher and Chan Ho Park the loser, while Jonathan Broxton earns the save. The series is tied 1-1.
- CC Sabathia holds the Los Angeles Angels to four hits and a run in eight strong innings, in a 4-1 victory that gives the New York Yankees a 1-0 lead in the ALCS. Hideki Matsui (2), Alex Rodriguez and Derek Jeter each drive in runs, and Mariano Rivera gets the save. Three Angels errors tie a franchise postseason record and lead to two Yankees runs, which serve as a support for Sabathia, who does not need all that much help to prevail in his duel against John Lackey.
- October 17 - Alex Rodriguez hit a tying home run in the bottom of the 11th inning to negate a Chone Figgins go-ahead RBI-single, and the New York Yankees score the winning run on a 13th inning error by Maicer Izturis to edge the Los Angeles Angels, 4-3, for a 2-0 lead in the best-of-seven ALCS.
- October 18 - Ryan Howard plays a key role in a four-run first inning and Cliff Lee dominates the Los Angeles Dodgers over eight innings, giving the Philadelphia Phillies an 11-0 win and a 2-1 NLCS lead. With his first-inning two-run triple off Hiroki Kuroda, Howard becomes the first player in Major League history to record an RBI in seven consecutive playoff games in the same year. Lee allows just three hits and struck out 10 in eight scoreless innings to improve to 2-0 with a 0.74 ERA in three starts this postseason. Howard is one game shy of matching the legendary Lou Gehrig, who holds the all-time record with an RBI in eight consecutive postseason games that spanned from 1928 through 1932.
- October 19:
- For the second straight game, the Los Angeles Angels and New York Yankees play into tense extra innings, until Jeff Mathis drives home Howie Kendrick in the 11th inning, and the Angels survive a second straight ALCS thriller, beating New York 5-4 to trim the Yankees' series lead to 2-1. Ervin Santana earns the win, while Kendrick homers and triples before singling with two outs in the 11th off Alfredo Aceves, who takes the loss.
- Jimmy Rollins lines a two-run double with two outs in the ninth inning off Jonathan Broxton and the Philadelphia Phillies rally past the Los Angeles Dodgers, 5-4, for a 3-1 lead in the NLCS. Brad Lidge gets two outs in the ninth to earn the win, while Ryan Howard hits a two-run home run to extend his Major League record to eight consecutive playoff games with an RBI within the same year.
- Three Phillies members make history during their 5-4 victory against the Dodgers in Game 4 of the NLCS. There have been 1,251 postseason games in MLB history, according to the Elias Sports Bureau. Only three players ever ended a game with a walk-off extra-base hit by a team that was one out away from losing: (1) Jimmy Rollins with his two-run double in the ninth inning off Jonathan Broxton in this game, (2) the Dodgers' Kirk Gibson with his memorable home run off Oakland Athletics' closer Dennis Eckersley in Game 1 of the 1988 World Series, and (3) the Brooklyn Dodgers' Cookie Lavagetto with his two-run double off Bill Bevens in Game 4 (and final game) of the 1947 World Series, when Yankees pitcher Bevens got within one out of the first no-hitter game in World Series history, and then lost it all. Also, Ryan Howard joins Lou Gehrig as the only players who have recorded an RBI in eight consecutive playoff games, a mark that Gehrig set 77 years ago, and also matches Mike Schmidt's career-club, playoff-record with his sixth career postseason home run. In addition to Rollins and Howard, Chase Utley surpasses the legendary Gehrig when he reaches base safely in his 24th consecutive postseason game. Former Orioles first baseman Boog Powell holds the Major League record by reaching safely in 25 consecutive postseason games that spanned from 1966 to 1971.
- October 20:
- Alex Rodriguez homers in his third straight game and CC Sabathia pitches five-hit ball on three days' rest, as the New York Yankees take a 10-1 victory over the Los Angeles Angels in Game 4 of the ALCS, moving just one win away from going to their 40th World Series. Rodriguez drives in a run for the eighth consecutive postseason game, tying a record that had been set by Lou Gehrig 77 years ago and tied by Ryan Howard less than 24 hours earlier.
- Kenji Johjima opts out of the final two seasons with the Seattle Mariners, allowing him to sign with a Japanese team. Johjima's contract gave him the right to end it by November 15 for the purpose of finishing his career in Japan. He gives up salaries of $7.7 million in 2010 and $8.1 million in 2011. Johjima hit .268 in his four seasons with Seattle, with 48 homers and 198 RBIs in 462 games. He holds the AL record for hits by a rookie catcher with 147 in 2006. His 18 homers in this season tied the Mariners' record for most by a catcher.
- October 21 - Jayson Werth homers twice, Shane Victorino and Pedro Feliz also connect, and the Philadelphia Phillies beat the Los Angeles Dodgers, 10-4, in Game 5 of the NLCS to win their second straight NL pennant. Ryan Howard is named Series MVP. Chase Utley ties a record set by Boog Powell when he reaches base safely in his 25th consecutive postseason game. The Dodgers lose in the NLCS to the Phillies for the second straight season.
- October 22 - Kendrys Morales drives in the go-ahead run with a two-out single in the seventh inning, and the Los Angeles Angels respond to the New York Yankees' six-run comeback moments earlier for a 7-6 win that trims the Yankees' ALCS lead to 3-2.
- October 25 - The New York Yankees win their 40th American League pennant (and the first in six years) beating the Los Angeles Angels, 5-2, in Game 6 of the ALCS.

- October 28 - The Philadelphia Phillies defeat the New York Yankees, 6-1, in Game 1 of the World Series at Yankee Stadium. Phillies pitcher Cliff Lee gives up an unearned run on six hits, while striking out 10 without walking a batter in a complete game effort. Chase Utley leads the Philadelphia attack with two solo home runs off left-handed CC Sabathia, the losing pitcher. It is the first time a left-handed batter has hit two homers off a lefty pitcher since Babe Ruth, when he did it against Bill Sherdel of the St. Louis Cardinals in Game 4 of the 1928 World Series. With a walk in the first inning, Utley also sets a Major League Baseball record by reaching base safely in his 26th consecutive postseason game, breaking the 25-game mark of Boog Powell from 1966 to 1971.
- October 29 - The New York Yankees even the World Series at a game apiece with a 3-1 victory against the Philadelphia Phillies. In the biggest start of his career, A. J. Burnett throws seven solid innings to get his first postseason win, holding the Phillies to only one run and four hits, while Mark Teixeira and Hideki Matsui provide the offensive support with solo home runs off Pedro Martínez, the losing pitcher. Mariano Rivera throws two scoreless innings in relief and earns the save.
- October 30 - The New York Yankees beat the Philadelphia Phillies 8-5, at Citizens Bank Park, to take a 2-1 advantage in the World Series. Alex Rodriguez belts the first video-reviewed home run in World Series history to support another winning Andy Pettitte effort, while Nick Swisher and Hideki Matsui add solo shots. Cole Hamels is the losing pitcher. Pettitte, who overcomes two homers from Jayson Werth, earns his Major League-leading 17th postseason win. Phillies catcher Carlos Ruíz hits a late homer in a lost cause.
New York Yankees celebrate after their 7-3 win against the Philadelphia Phillies and win the franchise's 27th World Series championship.
- November 1 - The New York Yankees put themselves one win away from their 27th World Series title, after a three-run rally in the ninth inning, to beat the Philadelphia Phillies 7-4. Johnny Damon sparks the rally with a two-out single and two stolen bases off reliever and loser Brad Lidge, before a hit-by-pitch to Mark Teixeira and a go-ahead RBI double by Alex Rodriguez. A two-run, RBI-single by Jorge Posada seals the victory. Both starters, Yankees' CC Sabathia and Phillies' Joe Blanton, give a good pitching effort. Joba Chamberlain is credited with the victory after one inning of relief, while Mariano Rivera earns the save. Damon also singles, doubles, scores and drives in a run early in the game. The Phillies' offense is led by Chase Utley, who hits an RBI double and his third home run of the Series, while Pedro Feliz adds a solo homer.
- November 2 - The Philadelphia Phillies get an 8-6 victory over the New York Yankees, which forces the World Series to Game 6 at Yankee Stadium. Chase Utley hits two home runs with four RBI and joins Reggie Jackson as the only players who have batted five home runs in the Series, a record that Jackson set in 1977, which gave him the nickname "Mr. October". Cliff Lee improves to 4-0 with a 1.56 ERA in his first postseason and Ryan Madson earns the save, while Raúl Ibañez adds a homer and two RBI. For the Yankees, Johnny Damon goes 3-for-4 with two runs and one RBI, while A. J. Burnett has a poor start, giving up six runs in just two-plus innings and is credited with the loss.
- November 4 - The New York Yankees beat the Philadelphia Phillies 7-3 in Game 6 of the World Series, to clinch their 27th World Championship title, the most in all of sports. Yankees DH Hideki Matsui, who gains Most Valuable Player honors, drives in six runs, tying the record set by Bobby Richardson (1960 WS) and Will Clark (1989 NLCS) for most runs batted in a postseason game, while Andy Pettitte, pitching on three days' rest, becomes the first pitcher to start and win the clincher in all three postseason rounds. Pettitte beat Minnesota and the Anaheim Angels in the earlier AL playoffs. Philadelphia falls two wins short of becoming the first NL team to repeat as World Series champions since the 1975-'76 Cincinnati Reds. Phillies second baseman Chase Utley ties Reggie Jackson's record with five home runs in a Series, but first baseman Ryan Howard strikes out 13 times to set a record in the Classic. The clincher marks the sixth time New York has defeated the defending champ in the Series.

New York Yankees teammates Mark Teixeira (225 points) and Derek Jeter (193) follow.

- November 24 - Albert Pujols of the St. Louis Cardinals receives his third National League MVP Award, tying eight others who also had three. Only Barry Bonds has more with seven. Pujols, who also won in 2005 and 2008, receives all 32 first-place votes and 448 points in balloting announced by the BBWAA. Florida's Hanley Ramírez, the NL batting champion, is second with 233 points, followed by Philadelphia's Ryan Howard (217) and Milwaukee's Prince Fielder (203).
