On August 2, 2011 — Mark Teixeira homers from both sides of the plate for the 12th time to set a new major league all-time record during the Yankees’ rain-shortened 6-0 victory in Chicago. The New York slugging first-baseman surpasses switch-hitters Eddie Murray and Chili Davis, who went yard from both sides of the dish 11 times during their careers.
