The longtime voice of the Astros, Hamilton was the Pirates' play-by-play man for four seasons, starting with 1976. Calling the 1979 championship season ensures that his work here will never fall entirely out of the public consciousness, but in Pittsburgh, Hamilton will always be remembered first and foremost as the man who replaced Bob Prince. I've never been a big fan of Hamilton's vocal style, but I'm not sure there's a man alive who would've been able to fill The Gunner's shoes. It's probably for the best that he ended up in Houston.
