It was an innocuous comment, thrown out at Candlestick Park one day in 1962 while lanky 6'4" Giants rookie pitcher Gaylord Perry took batting practice. "Hey, Alvin," San Francisco Chronicle sportswriter Harry Jupiter called out to manager Alvin Dark. "This Perry kid's going to hit some home runs for you." Dark turned to Jupiter and, as Perry tells it, replied, "There'll be a man on the moon before Gaylord Perry hits a home run." Seven years later, on July 20, 1969, Neil Armstrong took one giant leap for mankind. Less than an hour after that, Perry smacked his first major league homer, against the Dodgers at Candlestick. "True story," drawls Perry, now 70 and living in Spruce Pine, N.C., with his wife of 14 years, Deborah. "I could hit fine in batting practice."
