The American Association was formed in 1902 with eight franchises: Minneapolis, St. Paul, Milwaukee, Kansas City, Indianapolis, Columbus, Toledo and Louisville. The cities didn't change over the next 50 years, with the exception of the Toledo team spending two seasons (1914-15) in Cleveland.
The residents of Minneapolis and St. Paul were perfectly content with their "Association" status -- a league of stability, intimate ballparks and outstanding rivalries.
None was stronger than the Minneapolis Millers vs. the St. Paul Saints. The schedule-makers made sure the teams were playing a series over the holidays, so that two-ballpark doubleheaders could be played on Memorial Day, the Fourth of July and Labor Day.
The Millers and the Saints undertook a tradition where a morning game was played in the Millers' Nicollet Park and an afternoon game in the Saints' Lexington Park, or vice versa, on the holidays.
This wasn't a tough commute for customers interested in viewing both games. Nicollet Park was located on Nicollet and Lake, and Lexington Park was located on Lexington near Marshall.
Lake and Marshall are the same street in different cities, and a trolley ran along it -- until the tracks were ripped up over a five-year period (1949-54) to create a monopoly for buses.
There were two factors that substantially damaged the appeal of the Millers, the Saints and the Association: A) In 1953, the Boston Braves moved into Milwaukee's new County Stadium, making that beer town in a bordering state a major league city; and B) the public became fascinated with a revolutionary form of entertainment called television.
The arrival of the Braves in Milwaukee, and then the Philadelphia Athletics in Kansas City in 1955, caused great envy here on the northern prairie. We didn't want to be an Association town anymore, playing against the likes of Wichita, Kan.; Charleston, W.Va.; and Omaha.
