Sioux City Soos (1947-1960)
The Sioux City Soos of 1947-1958 were the fourth and final baseball club to play under the “Soos” name in the Northwest Iowa city. Earlier versions of the Soos played in 1904, 1908-1909 and 1940-1941. The latter day Soos joined the Class A Western League for its inaugural season in the summer of 1947. Sioux City won three Western League playoff crowns during a nine-year working agreement with the New York Giants of the National League.
