Serving as home from 1932 to 1938 to two of the Negro Leagues' most successful franchises, the Pittsburgh Crawfords and the Homestead Greys, Gus Greenlee Field opened in Pittsburgh in 1932 with a seating capacity of 7,500.  In addition to housing the Crawfords and Greys, Greenlee Field served as the practice site for the National Football League's Pittsburgh Pirates, who later became known as the Pittsburgh Steelers.
