By 1891, Major League Baseball would come calling. The American Association had previously been upgraded to Major League status (remember, this was well before the American League came into existence) and Milwaukee looked like a strong enough media market to support an MLB franchise. The A.A. had been looking to replace their Cincinnati team and Milwaukee's Borchert Field took their place on the roster. By 1892, the American Association was absorbed by the National League and the Milwaukee Brewers were not invited to join the merger.   Without an organization to play in, the Brewers joined a renegade "Major League" known as the Western League. The W.L. was hoping to pick up where the American Association left off and allow the teams not taken by the National League to compete in an MLB level of competition.
