In baseball’s early days, a batted ball that bounced once before clearing the fence was considered a home run. The last “bounced” home run in major league history was hit by Al Lopez of the Brooklyn Dodgers on September 12, 1930, at Ebbets Field. At the start of the 1931 season, the National League would join the American League, which had enacted the rule change in 1929, awarding a ground-rule double to the player who hits the ball over the fence on a bounce.
