Before the arrival of the Minnesota Twins in 1961, there was a long history of minor league baseball teams called the St. Paul Saints, as well as their crosstown rivals the Minneapolis Millers. One incarnation of the Saints participated in the Union Association, a short-lived major league, in 1884. A second incarnation was active in the Western League from 1894 to 1899, and became a forerunner of the modern Chicago White Sox. The third and most long-lived incarnation of the Saints was active in the American Association from 1915 to 1960.
