In [[baseball]] and [[softball]], a '''relief pitcher''' or '''reliever''' is a [[pitcher]] who pitches in the game after the [[starting pitcher]] or another relief pitcher has been removed from the game due to [[fatigue (medical)|fatigue]], injury, ineffectiveness, [[ejection (sports)|ejection]], high pitch count, or for other strategic reasons, such as inclement weather delays or [[pinch hitter]] substitutions. Relief pitchers are further divided informally into various roles, such as [[Closer (baseball)|closer]]s, [[setup men]], [[middle relief pitcher]]s, [[left-handed specialist|left/right-handed specialist]]s, and [[long reliever]]s. Whereas starting pitchers usually [[pitch count|throw so many pitches]] in a single game that they must rest several days before pitching in another, relief pitchers are expected to be more flexible and typically pitch in more games with a shorter time period between pitching appearances but with fewer [[innings pitched]] per appearance. A team's staff of relievers is normally referred to [[Metonymy|metonymically]] as a team's [[bullpen]], which refers to the area where the relievers sit during games, and where they warm-up prior to entering the game.
