A bullpen is an area of a baseball field that allows pitchers to warm up before entering a game. The bullpen is usually set to the side at one end of the team's dugout, but there is no rule for where it has to be. The bullpen often receives a lot of attention, especially toward the end of a game, as other pitchers may be called in to relieve the starter.
Many bullpen catchers are retired big leaguers, or players who ended their careers at the college or minor league level. Working as a bullpen catcher gives them a chance to participate with a major league team and make a contribution to the success of professional players.
