The St. Paul Saints, also known as the Apostles or the White Caps, were a replacement Major League Baseball team that represented St. Paul, Minnesota in the short-lived Union Association, which existed for the 1884 season only. The team began the 1884 season in the Northwestern League as the Apostles. In September of that year, after compiling a 24-48 record, the team jumped to the Union Association along with the Milwaukee Brewers. The club finished its short stint in the Association with a 2-6-1 record in nine road games, earning the distinction of being the only major league team not to play a single home game. The team was managed by Andrew Thompson. They played their home games at Fort Street Grounds.
Their top-hitting regular was pitcher/outfielder Jim Brown, who had five hits in 16 at bats, for a batting average of .312, hit four doubles, and a slugging percentage of .562. The team also included Charlie Ganzel, their catcher, who went on to play in 786 games in a 14 season career, most notably with the Detroit Wolverines and the Boston Beaneaters.
