The Rockford Forest Citys played their first and only season in 1871 as a charter member of the National Association of Professional Base Ball Players.
Rockford finished with 4 wins and 21 losses, 15½ games behind the champion Philadelphia Athletics club and good for last place.
Hastings had jumped from a Louisiana team to the Forest Citys in the spring and immediately begun playing for Rockford.
The star of the team was Cap Anson, who hit .325 for the Forest Citys and would go on to become the player-manager of the Chicago White Stockings for over 20 seasons.
