On July 26, 1922 — In several pregame fights between Yankee teammates, Bob Meusel and Wally Schang duke it out in the dugout. Then Babe Ruth and Wally Pipp take a turn. The players then turn on the Browns, beating them, 11 – 6. Ruth bangs two homers, Pipp adds another, and Schang chips in with a two-run triple.
