6th In a trade of major names, the Giants send Dick Bartell, Hank Leiber, and Gus Mancuso to the Cubs for Billy Jurges, Frank Demaree, and Ken O’Dea. The trade works best for the Giants as the New York-born Jurges will anchor the infield for 7 years; Chicago-born Bartell lasts just a season at Wrigley.
Larry MacPhail ends an agreement with the Yankees and Giants to ban broadcasts in the New York area and sells the radio rights of the Dodgers games to Wheaties.

14th The major leagues agree on a standard ball but disagree on increasing rosters from 23 to 25 players. Judge Landis will decide on 25.
