 Lou Gehrig hits his record 17th career Grand Slam in the Yankees' 8-3 win. He passes Babe Ruth for the all-time lead. I mean, 17 Grand Slams is nutty. But here's the other thing, if you really want to deep dive into it, how many at-bats with the bases loaded do you have to have to get 17 Grand Slams? He certainly didn't go 17 for 17. I mean, that just tells you how stacked those Yankees teams were.
