On June 10, 1974, Mike Schmidt hits what may be the longest single in major league history. The Philadelphia Phillies’ third baseman slams a ball off Astros hurler Claude Osteentoward center field, with enough distance to clear the fence at the Houston Astrodome. The ball suddenly hits a caroms of the public address speaker that hangs from the Astrodome’s ceiling hanging 117 feet in the air and 329 feet from home plate. Center fielder Cesar Cedeno fields the ball quickly and holds Schmidt to one base. The Rice University mathematics department calculates the Astrodome blast would have traveled 550 feet if left unimpeded.
