Bingo Long is based on former Black Baron Leroy "Satchel" Paige. Early in his career, Paige would call in his outfield while leading in the ninth inning against an amateur or semi-pro team and strike out the side. Bingo did a similar stunt in this movie. Leon Carter is a Josh Gibson-like power hitter, even playing the same position (catcher). "Esquire" Joe Calloway is an amalgam of another Black Baron, Willie Mays (in personality, talent, and fielding position) and Jackie Robinson (as being signed by a white team at the film's end).
