On this day in Yankee history...
1890: Casey Stengel is born.
1951: Joe DiMaggio makes a rare mental error against Detroit, catching a Steve Souchock fly ball in deep center and, thinking it's the third out, begins trotting in. It's only the second out, and George Kell scores from second base to make the score 4-2 in the 8th. Despite the lapse, the Yanks win, 5-4, with DiMag redeeming himself by knocking in the winning run in the 9th.

1977: Don Gullett picks up his 10th win of the year, a 9-3 victory over the A's. But it will prove to be his final win of the year when he injures his shoulder in the 7th inning and leaves the game.

1990: In a surprisingly harsh ruling, Commissioner Fay Vincent orders George Steinbrenner to resign as the Yankees general partner by August 20th, and bans him from day-to-day operation of the team for life. The ruling is a result of Steinbrenner's $40,000 payment to confessed gambler Howie Spira for damaging information about since-traded Yankee star Dave Winfield. When the news is posted on the scoreboard at Yankee Stadium during a game with Detroit, it draws a 2-minute standing ovation from the crowd.
1997: David Wells fires a three-hitter as the Yankees beat the A's 7-0. Tino Martinez hits his 36th homer and Luis Sojo has four hits.

2008: The Yankees, in need of catching help after losing Jorge Posada for the remainder of the season, acquire Ivan Rodriguez from the Tigers for Kyle Farnsworth.
2011: The Yankees complete a doubleheader sweep of the Orioles with a huge 1st inning in the nitecap, after winning the opener 8-3. The Bronx Bombers score 12 runs as they chase Zach Britton, just back from the minors, after only one out, but not before he gives up 9 runs. They roll to a 17-3 win, accumulating 24 hits, as Ivan Nova benefits from the outburst; Robinson Cano goes 5 for 5 with 5 RBI, while Nick Swisher hits a two-run homer in each game.
