 In order to keep from competing with the Chicago Mustangs of the former USA, the Spurs were forced to relocate.This was unusual because the Spurs already had a full roster of players in place, while the Mustangs had to form a whole new team from scratch.The first choice of destination was Milwaukee, Wisconsin, but Arthur Allyn Jr., the Mustangs' owner, had signed a contract with an exclusivity agreement for his Major League Baseball team, the Chicago White Sox, to play nine home games at Milwaukee County Stadium in the summer of 1968.
