 In June 1942, the Negro League Kansas City Monarchs played several games against the white "Dizzy Dean All-Stars" at major league ballparks, attracting large crowds.After three games, all won by the Monarchs, Landis ordered a fourth canceled, on the ground that the games were outdrawing major league contests.On one occasion, Landis intervened in Negro League affairs, though he had no jurisdiction to do so.
