This was an odd story that may or may not be true. Hall of Fame pitcher Gaylord Perry was most famous for throwing "spit" balls using Vaseline under his cap. Like most pitchers in the major leagues, he was not known for his ability to hit. In 1963, while taking part in batting practice, a sportswriter commented that Perry "had some power." Perry's manager at the time, Alvin Dark, scoffed at the comment and reportedly said, "Let me tell you something. There'll be a man on the moon before he ever hits a home run."
Fast forward to July 20th, 1969. The San Francisco Giants were playing the L.A. Dodgers at Candlestick Park. The public-address announcer informed the crowd that Neil Armstrong had just walked on the moon. About twenty minutes later, Gaylord Perry hit the first home run of his career.
