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.
Why do they call it a bullpen? A: There are many contradictory theories about the origin of the term bullpen in baseball. The most prevalent theory claims that the term arose because Bull Durham tobacco placed ads in every ballpark in the nation in 1910 and pitchers used the shade of the Bull Durham signs to warm up.
