11th Before an exhibition game in San Juan, Puerto Rico, Willie Mays and teammate Ruben Gomez get into a brawl. It starts when Gomez slips into the batting catch ahead of Mays, and batting practice pitcher Milt Ralat then refuses to throw. The sulking Gomez sits down on the plate, and Mays then steps to the side and directs the pitcher to throw to him there. Ralat then throws an insulting slow pitch which Willie barehands and fires back. He and Ralat exchange words and when Mays walks towards the mound, Gomez, brandishing a bat, attempts to interfere. Mays drops him with a right. The two later apologize to each other.
