John A. "Jocko" Flynn (June 30, 1864 in Lawrence, Massachusetts – December 31, 1907 in Lawrence, Massachusetts) was a Major League Baseball player for the World Champion Chicago White Stockings who played pitcher only in the 1886 season, during which the team again won the National League championship. Flynn's 23 victories were the most ever logged by a pitcher who only pitched a single season in the major leagues.
During this rookie year, Flynn developed arm problems which prevented him from appearing in the 1886 World Series, a best of seven contest that was ultimately won by he St. Louis Browns of the American Association, four games to two. Flynn's loss was painfully felt by the club, who also saw pitcher Jim McCormick go down after the second game of the series with a chronic foot ailment. Teams of the era typically only carried three pitchers and the loss of both Flynn and McCormick left the Chicagos with only their ace, future Hall of Famer John Clarkson, who was forced to start four of the six contests, going the distance in three.
Flynn's arm ailment kept him from pitching again. His 23 wins is the most ever by a pitcher who pitched in only one season in the major leagues.
