In the eighth inning of the A’s 13-7 victory over Chicago, Kansas City infielder Alex George makes his major league debut at Municipal Stadium. The 16 year-old shortstop handles two chances cleanly and strikes out in his only at bat in the game.

1955 – Slugger Mickey Mantle pulls a hamstring running out a bunt. He will make just two pinch-hit appearances in September, and he will go to bat in the World Series just 10 times.

In a move to shore up their pitching down the stretch, the Yankees buy Gerry Staley from St. Louis for the waiver price.

In his first and only major league appearance, Fred Van Dusen, entering the game as a pinch-hitter in the eighth inning for the Phillies, is hit by a pitch thrown by Humberto Robinson of the Braves. The 18 year-old bonus baby’s career ends with an on-base percentage of 1.000, but without a batting average.

1955 – OF Hank Bauer of the Yankees, pressed into emergency service as a catcher, permits a passed ball, setting up the winning run in a 9 – 8 loss to the White Sox.

1955 – Mickey Mantle’s 1st-inning three-run home run allows Bob Turley to coast to an 8 – 3 win over Washington. This is Mantle’s last home run of the year.

After sitting out since August 7 with a broken rib, SS Alvin Dark of the Giants falls and breaks his shoulder in a game against the Phillies.

Whitey Ford and Mickey Mantle celebrate Billy Martin’s return from the army; Ford throws 6 innings of no-hit ball against Washington before Carlos Paula spoils it in the 7th with Washington’s only hit. The Yanks win, 4 – 2, as Mantle hits his 36th home run, a 3-run shot. Mantle is 10 homers ahead of rivals Al Kaline and Ted Williams. New York stays a half-game behind the White Sox, who beat the 3rd-place Indians. Billy Martin will hit .300 in September, and New York will go on a 17-6 tear to win the pennant by 3 games.
