"Crusher" Crock was one of the world's greatest natural athletes and excelled in virtually every sport, a number of which he played professionally. Crock was so obsessed with winning that he would do almost anything to win, no matter how unsportsmanlike or even brutal it was. Finally, after he permanently crippled another player during a professional football game, Crock was fired from the team and barred from professional sports as a whole. Crock then decided to use his prowess in sports for crime. While disguised as the leader of a "mystery" team, he tried to rob the spectators at a polo match. However, he and his accomplices fled after clashing with the original Green Lantern. Later, Crock seemingly fell to his death while trying to kill Green Lantern. Crock somehow remained alive and returned as the Sportsmaster, as a costumed criminal who used his athletic ability and ingeniously gimmicked sports equipment to commit robberies.
