The all-time roster of the Major League Baseball franchise's Boston Reds spans one season in the Players' League (PL) in 1890 (team pictured), and one season in the American Association (AA) in 1891. In each season, the Reds were their league's champion. The Reds were an instant success on the field and with the public. The team signed several top-level players, and they played in a larger, more modern ballpark than the Boston Beaneaters, the popular and well-established cross-town rival. After the dissolution of the PL, the AA voted to allow the Reds into the new combined league. The Reds stayed intact by keeping several of their top players, and signed several other top-level players to fill the void of the departing players. When the 1891 season ended, the AA also folded, and the Reds were bought out by the surviving NL clubs. (Full list...)
