18th The case of the Allegheny Club versus Charles Bennett is won by Bennett. Prior to the 1882 season Allegheny signed Bennett to a $100 agreement which stated that he would sign an 1883 contract with Allegheny after the season. Instead, Bennett re-signed with Detroit. This case will later have bearing on the fight over the reserve rule during the Players’ League War of 1889-90.
