The Milwaukee Brewers served as a replacement team late in the 1884 Union Association season. Called the Cream Citys by both local papers, they had a record of 8–4. The team came to the UA from the Northwestern League, as did the St. Paul Saints, and were managed by Tom Loftus. They played their home games at the Wright Street Grounds.
Although their season was brief, it was highlighted by a 5-0 no-hitter tossed by Ed Cushman on September 28 and an 18-strikeout game by Henry Porter on Oct. 3.
They joined the new Western League for the 1885 season before folding and being replaced by a separate Milwaukee Brewers team that played the following year in the Northwestern League.
