Lou Gehrig hit his first grand slam home run on July 23, 1925. It would prove to be the difference in the game as the Yankees defeated the Senators 11-7. Over the course of his seventeen-year career with New York, Gehrig would hit a record-setting 23 grand slams, a mark since broken only by Alex Rodriguez, who finished his careers with 25.

i went scrolling down the career and active list of most grand slams and there’s no one in sight making a move up the ladder. maybe pujols with 12 at 33 years old could climb a bit or brian mccann with 10 at 29 years old or Cano with 8 at 30 years old. the biggest shocker is betancourt with 5.
Yuniesky Betancourt? Yeah, that is a shocker.
