In baseball, the bullpen (or simply the pen) is the area where relief pitchers warm - up before entering a game. A team 's roster of relief pitchers is also metonymically referred to as "the bullpen ''. These pitchers usually wait in the bullpen if they have not yet played in a game, rather than in the dugout with the rest of the team. The starting pitcher also makes his final pregame warm - up throws in the bullpen. Managers can call coaches in the bullpen on an in - house telephone from the dugout to tell a certain pitcher to begin his warm - up tosses.
