Green was a foolhardy baserunner and a .304 hitter for the Chicago Colts (Cubs) in 1898-1901. When American League raiders offered lucrative contracts to unhappy National League stars, Charles Comiskey landed Green, who became the White Sox right fielder in 1902. In 1906, with Green’s throwing arm burning out, Comiskey let him manage half the club in split-squad spring training. Green had his players roller-skating, believing it was better than jogging, but his training ideas did not please Comiskey. After Green’s spring squad lost most of its games, Green was outrighted to the American Association. He died in 1914 of complications from a beaning.
