During the regular 1974 Philadelphia Phillies season Schmidt hit a home run on June tenth when the ball hit the speaker.
On June 10, Schmidt hit what many felt should have been a home run when the ball hit the public address speaker that hung 117 feet above and 329 feet away from home plate at the Astrodome in Houston. The ball hit the speaker, fell to the field, and, by the Astrodome's ground rules, remained in play.
