The Chicago Pirates were a baseball team in the Players' League for a single season in 1890. The team played their home games at South Side Park (II). Their rivals were the National League Chicago White Stockings, which later became the Chicago Cubs.
The Pirates recruited most of the White Stocking's players, and for this reason the Pirates’ attendance was nearly fifty percent higher than the White Stockings. The Pirates’ owner, John Addison, was a wealthy contractor. Although Addison and his partner White Stocking second baseman Fred Pfeffer had signed mostly White Stocking players, they also signed four players from the St. Louis Browns of the American Association as well as a pitcher from the Columbus Solons of the American Association.[1] The team was managed by Charles Comiskey.
