The Bionic Mac died Saturday at the age of 83, leaving behind an enormous legacy: not only did he win 288 games over his 26-year career in the majors, but he was transformative figure in the game. In 1974, John became the first player to undergo the UCL reconstruction surgery that now bears his name and has since gone on to save the careers of countless pitchers. How is this guy NOT in Cooperstown?? #mlb #tommyjohn #dodgers #yankees
