In baseball, the term "bullpen" refers to the area where relief pitchers warm up before entering a game. It typically includes a section of the field near the dugout, where pitchers train and prepare to take the mound. Effective management of the bullpen is crucial for a team's success, as it allows managers to make strategic pitching changes during the game. A team's bullpen depth can profoundly affect its performance, making it a focal point of competitive strategy throughout the season.
