An independent minor league named the American Association formed in 1902, including a new Milwaukee Brewers club. Meanwhile, another new minor league club, the Creams, began play in a new version of the Western League. The Creams retained the lease on the Lloyd Street property, so the Brewers re-opened their ballpark, initially calling it Brewer Field, although the name Athletic Park endured until around 1920. Otto Borchert, son of Milwaukee brewing pioneer Frederick Borchert, purchased the field in 1920. The park thereafter became known as Borchert Field. Its original seating capacity was 4,800 (Pajot; 2009), but was later expanded to 10,000.
