Sportsman’s Park was the home field of both the St. Louis Browns of the American League, and the St. Louis Cardinals of the National League from 1920 to 1953, when the Browns relocated to Baltimore and were rebranded as the Orioles.
The physical street address was 2911 North Grand Boulevard. The ballpark was also the home to professional football: in 1923, it hosted St. Louis’ first NFL team, the All-Stars, and later hosted St. Louis Cardinals of the National Football League from 1960-1965, with Busch Memorial Stadium opening its doors in 1966.
The current site is the Bots and Girls Club and there is a field still there.
