This biography traces the hard life and colorful career of Iron Man McGinnity from his childhood working the coalfields of Illinois to his death in 1929. McGinnity may have been the most durable hurler in the history of the sport, often pitching both games of a doubleheader. He averaged more wins per season in his 10-year major league career than any pitcher in history, and continued to pitch for two more decades in the minor leagues before retiring at 54.
