On September 12, 1930 — The last major league bounced home run is hit by Dodger catcher Al Lopez at Ebbets Field as the NL joins the American League, which had enacted the rule change in 1929. The player who hits the ball over the wall on a bounce will now be awarded a ground-rule double.

With two on in the fourth inning, Robins catcher Al López – who was inducted into the National Baseball Hall of Fame as a manager in 1977 – roped the pitch of Cincinnati Reds pitcher Ray Kolp deep into the Ebbets Field alley. The ball hit the outfield grass and climbed over the left field wall. But instead of being awarded two bases, López’s modern day “ground-rule double” was correctly called a home run.
