On September 21, 1896, Connie Mack announced his intention to leave the Pirates in order to manage the minor-league Milwaukee Brewers of the Western League. Mack thus retired as a full-time player to accept his new role, which included a $3,000 a year salary and 25% ownership of the club. He managed the Brewers for four seasons from 1897 to 1900, their best year coming in 1900, when they finished second.
