Ted Williams wins the major league batting championship in Philadelphia.

The Red Sox win the first game of a doubleheader 12-11 and lose the second 7-1 to the Athletics at Shibe Park, as William collects six hits in eight at-bats. He had refused manager Joe Cronin’s offer to let him sit out the games in order to protect his .3995 batting average (which would have been “rounded up” to .400) and finishes at .406 to becomes the last major league player to date to bat .400 for an entire season.
