What is the Designated Hitter? Definition and Examples
The designated hitter (DH) is a player who bats in place of the pitcher every time the pitcher's spot comes up, without ever playing the field.
What is the Designated Hitter?
The designated hitter (DH) is a position-player role in which one batter hits in place of the pitcher for the entire game and never takes the field defensively. The DH occupies a slot in the batting order — usually the pitcher's slot — so the pitcher never has to bat. A team fields nine defenders plus a tenth offensive specialist, which means a lineup carries ten contributors instead of the eight position players who both hit and field. The DH exists to keep weak-hitting pitchers out of the batter's box and inject more offense into the game.
How the Designated Hitter Rule Works
The American League adopted the DH in 1973. The National League resisted for nearly five decades, forcing pitchers to bat in NL parks until Major League Baseball made the DH universal in 2022. Now both leagues use it in every game.
Core rules:
- The DH is named on the lineup card before the game and bats in a fixed slot all game.
- If the DH plays the field, the team forfeits the DH for the rest of the game and the pitcher must bat.
- A pinch-hitter or pinch-runner can replace the DH; the new player becomes the DH.
- Under the "Ohtani rule" (2022), a starting pitcher may also be the DH and remain in the lineup as a hitter even after he's pulled from the mound.
Worked Example
David Ortiz is the prototype. Across his career he hit primarily as a DH and finished with 541 home runs and a .286/.380/.552 slash line, almost none of it accumulated while playing first base regularly. Ortiz's value lived entirely in his bat — exactly what the role rewards.
Shohei Ohtani demonstrates the modern twist: in 2023 he batted as the Angels' DH while also serving as a frontline starting pitcher, hitting 44 home runs as a DH on days he didn't pitch and staying in the lineup as DH on days he did, thanks to the rule named after him.
Why the Designated Hitter Matters
The DH reshapes roster construction. Aging sluggers (Nelson Cruz, J.D. Martinez), bat-first prospects who can't field, and players recovering from injury all gain a home. It extends careers and raises league-wide run scoring. For fantasy and DFS, DH-eligible bats deliver counting stats without the defensive risk of being benched for a glove-first replacement. Front offices weigh "DH-only" players carefully because their entire WAR comes from offense — they get no defensive credit and a small positional penalty.
Limitations and Common Misconceptions
The DH is not a free roster spot — a full-time DH must hit enough to justify carrying a player who provides zero defensive value. Pure DHs are often docked in WAR via a positional adjustment, so a DH and a shortstop with identical slash lines are not equally valuable. The DH also does not mean the pitcher "can't" bat; a manager can choose to bat the pitcher and skip the DH, though virtually no one does. Finally, the DH is a lineup slot, not a fixed person — teams frequently rotate players through it to rest regulars.

In Legends Deck, a card's DH eligibility unlocks lineup slots without exposing the player to fielding events, so glove-light sluggers like Ortiz-type cards keep their full offensive ratings live while avoiding the defensive-error rolls that drag down a poor fielder's in-game value.
