In early baseball history, it was not uncommon for players to serve as player-managers; that is, they managed the team while still being signed to play for the club.
[3][needs update] The dual role of player-manager was formerly a common practice, dating back to John Clapp, who performed the task for the Middletown Mansfields in 1872.
