What Is DH In Baseball? The Rule That Changed Baseball

Do you know what a “DH” is and why it’s used in baseball? You must have heard this term while watching a baseball game. You may have heard it, but not sure what it means. 

OK, you’re not the only one. The designated hitter is shorthand for DH. It’s a common baseball word.

The DH, or designated hitter, is the player who bats instead of the pitcher. Nobody else bats for the pitcher or anyone who takes the pitcher’s place. The designated hitter doesn’t have to play defense, either.

The American League adopted the use of designated hitters in 1973, but the National League did not implement this rule before the 2022 season.  

In 2022 MLB introduced the DH rule in both leagues, which is called the Universal DH rule. 

Let’s find out in detail. 

What is the designated hitter (DH) position?

The designated hitter, often abbreviated as DH, is a baseball player who is in the lineup to bat for the pitcher. 

Because of the DH regulation, each side can have one player (the DH) who is entirely responsible for hitting and does not take part in defense. 

Since pitchers are usually the game’s worst hitters, this position was created to give the offense a boost. 

Managers will often employ the DH strategically to give regular field players a day off while still having them bat in the lineup or to help a slumping player receive additional at-bats. 

It’s important to remember that once a designated hitter (DH) is in the lineup, switching him or her to defense means that the team no longer gets to use the DH for the rest of the game.

If the pitcher moves into the DH place, the DH position is taken out of play for the rest of the game. Any new pitcher who enters the game at that point must bat in that position. 

The same rule applies to pinch hitters; once they’re utilized, the designated hitter is out of the game for the rest of the innings.

David “Big Papi” Ortiz of the Boston Red Sox is a perfect example of a designated hitter. 

In the designated hitter role, where he was not forced to play defense, Ortiz helped The Red Sox win numerous games playing as a DH.  

Some baseball fans feel that the designated hitter position and rule are not good for the game’s authenticity, while others see it as an exciting innovation. 

The designated hitter, though, will remain an integral element of baseball for the foreseeable future.

Rules for the Designated Hitter

  • Establishing the DH: The DH must be established before the game starts. If the coach doesn’t establish the DH before the game, the team cannot use the DH for the entire game.
  • Role of the DH: The Designated hatter is a player who bats in place of the pitcher. The DH does not play defense. Their role is solely to bat in the lineup.
  • Starting Lineup: The DH must be selected prior to the game, and that selected hitter must come to bat at least one time unless the opposing team changes pitchers.
  • DH Batting for the Pitcher: The DH can only be used to bat for the pitcher and no other position in the lineup. It’s specifically designated to enhance the pitcher’s offensive capabilities.
  • Cannot Change Positions: Once a DH, always a DH. The DH cannot move to a fielding position during the game. If the DH moves to a fielding position, this terminates the Designated Hitter role for the remainder of the game.
  • Pitcher Becomes a Batter: If a pitcher moves to a hitting position in the lineup, he then becomes part of the lineup, and the team forfeits the use of the DH for the rest of the game.
  • Replacement: If the DH is substituted by another player, that player becomes the new DH. The original DH is out of the game and cannot return.

Updated DH Rule in the MLB in 2023 (Universal DH Rule)

Previously, the DH Rule was only applied in the American League, but the National League did not use this rule. When two teams from these two leagues competed, the rule was applied according to the home ground. 

But MLB made a major change in the 2022 season. According to the Collective Bargaining Agreement (2022 – 2026), DH rule will be applied in both leagues. 

This updated DH rule is known as the Universal DH rule. This will now make a level playing ground for both leagues. 

Updated DH Rule in the MLB

Why is there a Designated Hitter in Baseball?

The main objective is, of course, to increase the intensity of the play. You have to understand that pitchers excel at throwing the ball. On the other hand, they are typically less proficient at hitting.

As a matter of fact, most pitchers have poor hitting reputations.

Therefore, the purpose of the designated hitter is to replace the pitcher with a more powerful hitter in the batting order. This not only boosts the odds of scoring but also introduces a new strategic element.

Having a designated hitter also helps prevent injury to pitchers. The act of pitching requires considerable physical effort. 

Pitcher fatigue and injury are both worse when they are also required to bat. A team’s pitchers can rest and concentrate on their primary task of pitching with the help of a designated hitter.

On the other hand, the deployment of a designated hitter is a strategic decision that can have a major impact on the final score.

A designated hitter (DH) cannot switch to defense during a game once they have been designated as a DH for that inning. 

So, the addition of the designated hitter rule has made baseball a far more interesting and strategic game. Fans are on the edge of their seats during this exciting juncture of the game.

A DH bats for a pitcher

DH in the Minor League

Minor League Baseball is the lower level of professional baseball’s league hierarchy that prepares players for the “Majors” of MLB. 

Here is where young talent is nurtured, honed, and trained for the big leagues. The Designated Hitter (DH) has an important part in games at this level, just as they do in the major leagues.

DH regulations have traditionally been the same between the major leagues and the minors. 

It meant that American League teams always used the designated hitter, and National League teams only did so when playing American League opponents or in American League venues.

Major League Baseball stated in early 2021 that the DH rule, regardless of affiliation, would be implemented across all Double-A and Triple-A leagues. 

Because of this ruling, the lower leagues are now all on the same page, and there is renewed interest in whether or not the National League will adopt the DH rule at the Major League level.

DH in College League Baseball (NCAA)

The DH also plays a significant part in NCAA (National Collegiate Athletic Association) baseball.

Similar to professional and minor league baseball, the designated hitter (DH) is used in college baseball to bat in place of the pitcher to increase scoring and excitement. 

The NCAA has more relaxed restrictions for baseball, and they even have a unique notion called a “dual role player.” 

If a player is in the starting lineup with two different positions (pitcher and designated hitter), they can switch back and forth between the two roles as needed. 

This regulation acknowledges the fact that many collegiate players possess transferable skills and may excel in many positions.

DH in the High Scholl League (NFHS) 

According to NFHS regulations, any starting player, not just the pitcher, can be designated as a DH. 

Since a DH can be substituted for a poorer hitter at any position in the lineup, this law gives high school coaches more strategic options and flexibility.

Furthermore, the NFHS has incorporated the idea of a “double DH” in recent modifications. 

A rule change like this one, which permits the same player to serve as both the designated hitter and the defensive player, is meant to boost player engagement and growth.

DH in Little League 

Unlike at other levels, Little League Baseball does not let players specialize in designated hitters.

An alternative regulation that emphasizes development and participation above strategy is a continuous lineup in which all players take turns batting. 

This signifies that a player is still in the lineup to bat even if they are not actively participating in defensive duties for that inning. 

This rule supports Little League’s goals of promoting a love of the game, teamwork, and equal play. 

It’s a great way for kids to get some practice at the plate in game conditions.

Nonetheless, the DH rule’s application may differ according to the regulations of each league or tournament. For instance, certain leagues may have different DH rules, such as permitting any player besides the pitcher to DH.

The New Double-Hook DH Rule (Experimental) by MLB

A new “Double-Hook” DH rule has been introduced in the Atlantic League in 2023 before being implemented league-wide. 

The DH will be allowed as long as the starting pitcher is still in the game under this rule. A team’s relief pitchers must hit for themselves or be replaced by pinch hitters once the starting pitcher is removed from the game.

This rule makes strategic decisions about when to remove the starting pitcher from the game more important. Because of this, clubs may be more inclined to keep their starting pitchers in for longer innings, which might speed up the game.

History of the DH in baseball

In baseball, the idea of a “Designated Hitter” (DH) goes all the way back to the 1800s. The National League (NL) tried out a 10-man lineup with a designated hitter (DH) in 1891, but the rule was quickly abandoned. 

However, the American League (AL) would come back to this idea in the latter part of the century.

There was a drop in scoring in baseball during the late 1960s and early 1970s. Major League Baseball examined ways to improve the game’s entertainment value as fans grew bored with games featuring few runs. 

There was growing support for the use of a designated hitter (DH), a player who bats in instead of the pitcher.

Designeted hitter was introduced in 1973 by American League

The AL agreed to try out the DH rule for three years beginning in 1973. 

On April 6, 1973, Ron Blomberg of the New York Yankees became baseball’s first designated hitter.

The experiment was a success since it led to more goals being scored and, consequently, more people attending the game. As a result, the DH rule is now the AL’s official policy.

There was still pushback from the NL, though. This rule mismatch between the leagues has developed interesting tactical implications over the years. 

Especially during the World Series, when both the American League and National League must adapt their plans to the home league’s regulations.

In 2020, the NL briefly adopted the DH rule in response to the unprecedented circumstances of the COVID-19 pandemic.

As part of their CBA for 2022–2026, the National League agreed to implement the designated hitter. 

Impact of the DH on strategy and gameplay

The DH rule, which has been in effect in the AL since 1973, has had a significant impact on baseball’s strategy and gameplay. 

The change in how pitchers approach games is one of the most consequential effects. With a designated hitter in place, the pitcher can concentrate exclusively on their pitching without having to worry about getting on base. 

As the pitcher’s batting position is less likely to become a disadvantage as the game progresses, they may be able to stay in for more innings. 

For instance, supposing the bases are loaded, and the pitcher is up to bat.

When there is no designated hitter, managers have to decide whether or not to let their pitchers bat when they know they likely won’t drive in any runs, thereby wasting a crucial scoring opportunity. 

Should they risk the pitcher’s outstanding performance by taking him out of the game for a pinch hitter? Leagues that allow a designated hitter do not face this conundrum, leading to a totally different strategic dynamic.

Because of the DH rule, teams can now field lineups that feature more batters with less defensive versatility. David Ortiz, well known by his nickname “Big Papi,” is often cited as an illustration. 

Despite his lackluster defensive abilities, Ortiz became one of the most feared designated hitters in MLB history.

With the DH rule in place, Ortiz was able to maximize his offensive contributions while limiting his defensive burden for the American League’s Boston Red Sox.

The DH rule is what made this a reality.

Controversies Surrounding the DH Rule

It’s been said that if every player isn’t expected to hit and field, then the game isn’t truly baseball. 

Because it allows a player to focus solely on hitting, they argue, the DH rule spoils the sport and makes it less fair.

For games between leagues and the World Series, where the league rules with the home club apply, this creates an unfair advantage, they say. Though Now they can not say that as MLB updated the rule.

The DH rule has been criticized because some believe it simplifies the game’s strategy. Baseball purists praise the managers who have difficult choices when the pitcher’s slot in the lineup is reached at a crucial juncture in the game. 

They say the DH rule takes away strategy and complexity from the game because managers don’t have to think about things like who should pinch bat for the pitcher or how to handle the bullpen.

What is Shohei Ohtani Rule?

A new regulation in Major League Baseball (MLB) permits a player to be classified as both the pitcher and designated hitter (DH) in the same game. This rule is known as the “Shohei Ohtani rule,” in honor of the Los Angeles Angels’ two-way star.

The replacement pitcher is still eligible to bat in the designated hitter spot for the remainder of the game under this rule. 

When a team’s starting pitcher (also the DH) is removed from a game, the team retains its designated hitter. This rule was made to help stars like Shohei Ohtani, who is great at both hitting and pitching.

The Ohtani rule will remain in effect for the full five years of the present collective bargaining agreement. The game of baseball will benefit from this rule change because of the added strategic depth and tactical maneuverability it will provide.

Is There a Change in the DH Rule for the World Series? 

The DH rule was previously implemented during World Series games hosted by the American League. 

Pitchers had to take turns batting when games were played in National League stadiums without the DH. This “when in Rome, do as the Romans do” approach was adopted so that both leagues could keep their unique identities.

However, the universal DH rule has been implemented recently. To help restore competitive balance between the two leagues and level the playing field in free agency, this rule allows for a DH in both American League and National League games.

What is the difference between a Designated Hitter and a Pinch Hitter?

Designated Hitters bat in place of pitchers but don’t play field. In contrast, a pinch hitter is a substitute batter sent in to replace a player in a specific batting scenario, usually when the manager thinks they can hit better.

Who is the Best DH of All Time? 

David Ortiz: “Big Papi” is regarded as the greatest DH ever. He helped the Boston Red Sox win three World Series titles during his career. Ortiz has .286 batting average with 541 home runs in his career.

Edgar Martinez: The Seattle Mariners’ Edgar Martinez was one of the few players to play his whole career as a DH. He became the first DH to be elected into the Baseball Hall of Fame in 2019 with a .312 career batting average.

Harold Baines: A successful DH, Baines played for the Chicago White Sox and Baltimore Orioles. He was inducted into the Hall of Fame in 2019 after a batting average of .289 with 384 home runs.

Frank Thomas: “The Big Hurt” played first base and DH. Career highlights included a .301 batting average, 521 home runs, and two MVP honors. He entered the Hall of Fame in 2014.

Paul Molitor: A versatile player, excelled as a DH. His career batting average was .306 with almost 3,000 hits. The Hall of Fame inducted Molitor in 2004.

Can a Pinch Hitter Replace the DH? 

A DH can be replaced by a pinch hitter during a game. In Major League Baseball, the designated hitter (DH) position is automatically filled by the player who enters the game instead of the DH for any reason (pinch-hitting, pinch-running, etc.).

You should keep in mind that the designated hitter cannot return to the game once he or she has been replaced by a pinch hitter. When the designated hitter is out, the pinch hitter bats in his place for the rest of the game.

Final Words

The designated Hitter rule has changed baseball, forcing strategic changes and sparking discussion among fans and commentators. 

Critics say it detracts from the conventional game, but others say it boosts offense and adds intricacy. 

The DH rule highlights sports’ continual conflict between tradition and innovation, representing modern baseball’s evolution. The DH rule will remain a hot topic in baseball as the game evolves.
