- In their 9–2 win over the visiting Royals, the White Sox become the sixth team in major league history to hit four consecutive home runs, with Jim Thome, Paul Konerko, Alexei Ramírez and Juan Uribe connecting in the sixth inning.

This marks the first time two players hit for the cycle on the same day since September 17, 1920, when Bobby Veach of the Tigers and George Burns of the New York Giants do it, according to the Elias Sports Bureau.
- September 3 – In the Yankees' 8–4 win over the Rays, a home run hit by New York's Alex Rodriguez is the first ever to be reviewed by instant replay. Though the ball is initially ruled a home run, Tampa Bay manager Joe Maddon argues the ball was close enough to the left field foul pole to necessitate a review. After a conversation among the umpires, crew chief Charlie Reliford agrees to the review and eventually upholds the home run call.
- September 8:
- Pinch-hitting for Houston, Mark Saccomanno homers on the first pitch he sees in the major leagues to help the Astros beat the visiting Pittsburgh Pirates, 3–2.

Kouzmanoff hits a grand slam on the first pitch against the Texas Rangers on September 2, 2006, becoming the first major leaguer to hit a grand slam on his first pitch.
- Gary Sheffield, four home runs short of the coveted 500 mark, provides another milestone for Major League Baseball. His second home run of the night is the 250,000th in major league history, and the Tigers beat the visiting Athletics 14–8. Sheffield collects five RBI, including his 13th career grand slam. Both homers come against Gio Gonzalez; the rookie pitcher also puts himself in the history books when he hit Mike Hessman with pitches twice in the second inning. It is only the fifth time in modern baseball history that a batter is hit twice in the same inning, the second time in the American League. The first is Brady Anderson on May 23, 1999, when he is hit twice in the first inning by Mike Morgan.
- Angels center fielder Torii Hunter gets caught in a rundown between third and home, and is tagged out relatively easily by Yankees catcher Iván "Pudge" Rodríguez. Hunter trips slightly over the bat at home plate, and bumps Pudge after the play. Rodriguez, in turn, shoves Hunter while walking toward the mound. That prompts Hunter to shove Rodríguez, resulting in a bench-clearing brawl. Both Hunter and Rodriguez are suspended two games by Major League Baseball, and neither appeals the suspension. Angels pitcher John Lackey receives an undisclosed fine by MLB for his involvement.

Pedroia also becomes the eighth player in team's history with 50 doubles in a season, giving him 69 extra-base hits this season, to move into a first-place tie with Bobby Doerr (1940) on Boston's all-time list for extra bases in a season by a second baseman.
- Hanley Ramírez hits his 30th home run, which combine with his 33 stolen bases to make him the second player in Marlins history to have a 30–30 season. Ramírez and the Marlins roll to their fourth consecutive victory, a 4–2 win over the visiting Nationals. Preston Wilson is the first Marlin player to achieve the feat, with 31 homers and 36 steals in 2000.

- September 19 – Rays first baseman Carlos Peña is awarded a home run after the original ruling of a ground-rule double due to fan interference is overturned by umpire Gerry Davis following an instant replay consultation during an 11–1 Rays victory over the Twins.

Since the runners were moving with two outs, all three come in to score and Ellsbury stops at first base. Anaheim went on to win the game, however, 5–4 in 12 innings. The win for the Angels snaps an 11-game postseason losing streak to Boston, a major league record.
