Inbaseball, apinch hitter (PH) is a substitutebatter. Batters can be substituted at any time while theball is dead (not in active play); themanager may use any player who has not yet entered the game as a substitute. Unlikebasketball,American football orice hockey, and in a similar way toassociation football, baseball does not have a free substitution rule (at the professional level) and thus the replaced player is not allowed back into that game. The pinch hitter assumes the spot in the batting order of the player whom he replaces. Pinch hitters are commonly used to replace a weak hitter (often the pitcher) or to gain aplatoon advantage.

The player chosen to be a pinch hitter is often a backup infielder or outfielder whose defensive skills are limited. InMajor League Baseball (MLB),catchers are less likely to be called upon to pinch-hit, because most teams have only two catchers.Pitchers are rarely used as pinch hitters, because they tend to be worse hitters than other players on the team. However, some pitchers have been used as pinch hitters; this tactic had almost vanished by the 1980s, but later saw a comeback in situations when benches have diminished due to injuries, offering few other options beyond a team's 12 or 13 pitchers.

MLB, thePacific League ofNippon Professional Baseball (NPB), theKBO League (in South Korea), theLiga Mexicana de Béisbol (inMexico), and various other leagues use thedesignated hitter rule, such that pitchers seldom bat. This eliminates one possible situation in which a pinch hitter may be more desirable.

Forstatistical andscorekeeping purposes, the pinch hitter is denoted by "PH".^[1]

Pinch hitters are often used to replace a starting player because of injury or when the pinch hitter is thought to have a better chance of reaching base or helping other runners to score.

When thedesignated hitter rule is not in effect (e.g., in theCentral League inNPB, in theNational League before 2022 andAmerican League before 1973 inMLB and leagues such as theAtlantic League which use thedouble hook rule), pinch hitters are often substituted for thepitcher in the middle or late innings of a game. This is because pitchers are often poor hitters and may become less effective after six to seven innings of pitching. Thus, as the manager often plans to replace the pitcher in the next inning, the player being replaced cannot re-enter the game, the major downside of using a pinch hitter.

This use of a pinch hitter is often part of adouble switch, in which arelief pitcher replaces a defensive player who will not bat soon, and at the same time a defensive player replaces the pitcher who is scheduled to bat soon. If a player acts as a pinch hitter and his team bats around in the inning, he may come to the plate a second time. The second (and subsequent) times he bats in the inning are not considered pinch-hitting appearances.

The pinch hitter need not (but may) assume the same position as the player for whom he pinch-hits as long as some other player assumes that position. For example, on August 16, 2009, theWashington Nationals'Ryan Zimmerman pinch-hit for second basemanAlberto González and then remained in the game at third base, with previousthird basemanRonnie Belliard switching positions to play second base after the change.^[2] Alternatively, the manager may designate another player to replace the pinch hitter; this scenario is common when a team pinch-hits for a pitcher without executing a double switch, such that the new pitcher then replaces the pinch hitter and assumes the previous pitcher's place in the batting order.

If a pinch hitter hits for theDH, the new pinch hitter stays in the game as a DH, and may not be used in the field. If the new DH does take the field, then the team forfeits the DH for the remainder of the game (thus, causing the pitcher to enter the batting order).
