There are Some Crazy Baseball Rules - See Old HR Rules

Lou Gehrig hit 46 homers and had 184 RBIs in 1931.  On this day he hit one out of the park and it quickly bounced back to a fielder who caught it.  The baserunner thought that the ball was caught so he headed to the dugout.  Gehrig was called out for passing the baserunner. 

Gehrig tied for the AL HR lead with Ruth.  This cost him his own title.  His 148 RBIs is the AL record.  There would have been two more.  Let's check out the box score.

Gehrig is listed as being 1-for-4 with a triple and an RBI.  In the first inning there was a walk before Gehrig's "homer".  Not mentioned in the story on nationalpastime.com - there was no second base umpire that could have helped with this call in centerfield.
