Dec 12, 1930: MLB changes HR rule

No more "bounce HR"

NEW YORK, NEW YORK - Did you know that a fair ball that bounced once into the stands used to be a home run? That was the case in the National League until the 1931 season. At the winter meetings on this date in 1930, the Major League Baseball joint rules committee decided to make standard what the American League enacted the year before, no more "bounce home runs." In order to be a home run the ball had to reach the stands on the fly.

The question many had and have is, how many "bounce home runs" did Babe Ruth have, and should there be an asterisk next to his name? Some estimate he hit about 30 "bounce home runs." It all probably evened out however, because some balls the Babe hit clearly far enough to be home runs were ruled foul because of where they landed, the rule at the time, rather than where they left the field of play, the rule today.

Another rule in place at the time and since changed is, if a ball was hit over the fence to end a game, the hitter only got credit for as many bases as it took to drive in the winning run. Chances are Babe Ruth would have had more than 714 home runs had he played today.
