Lou Gehrig's grand quest begins
Gehrig's record-setting quest began against Washington Senators pitcher Firpo Marberry in the seventh inning that day. The shot was also Gehrig's second home run of the game.
Fourteen years later, on Aug. 20, 1938, the Iron Horse hit is final grand slam, tallying 23 for his career.
Gehrig stood alone in the record book for 74 years until fellow Yankee Alex Rodriguez tied his mark on June 12, 2012. The two sluggers remain tied atop the list.Career grand slam leaders:
