Rogers Hornsby is named manager of the St. Louis Cardinals, replacing Branch Rickey, who remains as general manager. Hornsby will be the only player-manager to win the Triple Crown, which he does by topping a .400 batting average for the third time in four years, hitting .403 with 39 home runs and 143 RBI. Hornsby assumes his new position halfway through a twin bill in Forbes Field, both ends of which are won by the World Series-bound Bucs, and each of which feature opposite field home runs from Rajah.
