September 8, 2007 - Alex Rodriguez continues to lead the Yankees in their playoff hopes with an 11-5 win over the Kansas City Royals. He homers twice off rookie pitcher Brian Bannister. The first of the homers is his 49th of the year and breaks the record for homers by a third baseman. Previously, Mike Schmidt and Rodriguez (2005) had shared the record at 48 homers. Rodriguez already held the single-season record for shortstops, giving him the high watermark at two positions. September 8, 2008 Gary Sheffield hits a grand slam for the official 250000th homer in MLB history. The blow is Sheffield's 2nd homer of the day and his 13th career grand slam. September 8, 1998 Mark McGwire breaks Roger Maris' single-season home run mark by clouting his 62nd of the year off Steve Trachsel in the 4th inning of the Cardinals' 6 - 3 win over the Cubs in St. Louis. September 8, 1985 - Reds' player-manager, Pete Rose gets two hits at Wrigley Field off Cubs' hurler Reggie Patterson, including a historic single to tie Ty Cobb's career record of 4191 hits.

His 40th home run also breaks Darryl Strawberry's Met club record for most homers in a single season.
