Designated hitter

The designated hitter (DH) is a baseball rule that allows a team to designate a player to bat in place of the pitcher without requiring that player to play a defensive position in the field, thereby enabling the team to maintain ten players in the batting order while keeping the standard nine defensive players. Adopted by Major League Baseball's (AL) on January 11, 1973, the rule aimed to boost offensive output, shorten games by reducing pitching changes, and protect pitchers from injuries associated with batting. The first official DH in MLB history was of the New York Yankees, who walked in his debut plate appearance against the Boston Red Sox on April 6, 1973. For nearly five decades, the DH was used exclusively in AL games and select interleague or postseason matchups, while (NL) pitchers were required to bat, creating a notable strategic and stylistic divide between the leagues. In 2022, MLB introduced the universal designated hitter rule, applying it to both leagues in the regular season to standardize play, increase scoring, and accommodate modern player workloads, though special provisions exist for two-way players like who can both pitch and serve as the DH. The DH role has profoundly shaped baseball strategy and player development, favoring power hitters who excel at the plate but may lack elite defensive skills, and allowing aging stars to contribute offensively without fielding demands. Iconic DHs include Edgar Martinez, whose .312 career batting average and 309 home runs earned him Hall of Fame induction primarily as a DH; David Ortiz, the three-time World Series champion who hit 541 home runs and won the Outstanding Designated Hitter Award eight times; and Frank Thomas, a two-time AL MVP with 521 home runs who thrived in the role later in his career. More recently, Shohei Ohtani has redefined the position as a two-way superstar, earning five consecutive Outstanding DH Awards from 2021 to 2025 while also pitching at an elite level. The rule's implementation has correlated with higher run production in adopting leagues and remains a cornerstone of MLB's efforts to balance tradition with contemporary game dynamics.

Rules in Major League Baseball

Universal Designated Hitter Rule

The Designated Hitter (DH) rule, as outlined in Rule 5.11 of the Official Baseball Rules, permits a team to designate a to bat in place of the , thereby allowing for a 10-player lineup while the remains on the field solely for defensive purposes. The DH must be selected prior to the game and listed on the lineup card, batting in the 's position in the order without entering the field defensively unless substituted into a position. This setup ensures the DH bats at least one time in the game unless the opposing club changes . The universal adoption of the DH rule occurred as part of the 2022-2026 Collective Bargaining Agreement (CBA) between (MLB) and the MLB Players Association, making it a permanent feature in both the (AL) and (NL) for regular-season games and eliminating the requirement for pitchers to bat. Prior to this, the rule had been used experimentally in the AL since 1973, but the 2022 CBA extended it league-wide to standardize gameplay and enhance offensive opportunities. Regarding substitutions, the DH may be replaced by a pinch-hitter or pinch-runner, but such a substitution is permanent, and the DH role cannot be reinstated for the remainder of the game. If the DH enters the field defensively, the pitcher must then assume the batting position in the lineup. Similarly, if the pitcher is removed for a pinch-hitter or pinch-runner, the DH role terminates, requiring the new pitcher to bat in that spot. These provisions maintain the integrity of the 10-player structure while preventing mid-game manipulation of the batting order. In terms of lineup construction, the universal DH rule enables managers to select specialized hitters who possess strong offensive skills but may have defensive limitations, optimizing the team's overall batting production without compromising the pitching staff's defensive alignment. This approach, which originated as an experiment in to address declining attendance and offense, now applies uniformly across MLB.

Special Provisions for Two-Way Players

In 2022, updated Rule 5.11 of the Official Baseball Rules to include special provisions for two-way players, allowing a player designated as both a and the designated hitter (DH) to be treated as two separate roster spots for lineup purposes. This amendment, informally known as the " Rule," permits the player to continue batting as the DH after being removed from pitching, or vice versa, without forcing the team to lose the DH spot or make additional substitutions. Eligibility for this provision requires the player to be pre-designated as a on the active 26-man roster, having pitched at least 20 innings and had at least 3 plate appearances in at least 20 games as a or designated hitter during the prior . The rule applies exclusively to starting lineups; a cannot be inserted into both roles mid-game, and the designation must be announced before the game begins. Shohei Ohtani has been the primary beneficiary of this rule. During the 2022 and 2023 seasons with the Los Angeles Angels, Ohtani frequently started as both pitcher and DH, allowing him to contribute offensively throughout games after exiting the mound early due to pitch count limits; for instance, in 2022, he pitched 166 innings while batting .273 with 34 home runs. In 2024, limited by injury to DH duties with the Dodgers, Ohtani did not utilize the provision. He returned to two-way play in 2025, making 14 starts as pitcher with a 2.87 ERA over 47 innings while batting .282 with 55 home runs and earning the National League Most Valuable Player Award, and applying the provision during the Los Angeles Dodgers' 2025 World Series victory over the Toronto Blue Jays, including starting Game 7 on the mound (2.1 innings pitched) and continuing to bat as DH. Limitations include that if the two-way player is injured, ejected, or voluntarily removed from both roles simultaneously, the team reverts to standard DH rules, forfeiting the DH spot if the replacement pitcher enters the batting order. Additionally, no other two-way player can immediately replace the original in both roles, preventing teams from cycling multiple such players in a single game. Retroactive designations are prohibited, ensuring the provision only aids pre-planned two-way usage. The rationale behind the rule is to promote and facilitate two-way play without imposing unnecessary defensive or lineup penalties, addressing the unique challenges faced by versatile athletes like Ohtani in an era of universal DH adoption.

Historical Development

Origins and Early Adoption

The concept of a designated hitter, a player who bats in place of the without entering the field, traces its roots to the late in variants aimed at enhancing offense and protecting pitchers from the physical demands of batting. Early proponents, including president John Heydler in 1928, suggested allowing a substitute batter for pitchers to speed up games and reduce injuries, building on informal practices in and semi-professional play during the 1880s and 1890s. By the 1960s, amid concerns over pitcher dominance following the "Year of the Pitcher" in 1968—when league-wide batting averages dipped below .250—the idea gained traction in to invigorate scoring and fan engagement. In 1969, the (Class AAA) adopted the rule on a trial basis, followed by four other , resulting in noticeable increases in runs scored and game pace without major disruptions. Major League Baseball conducted initial experiments with the designated hitter during in 1969, where teams could opt for a "designated pinch hitter" to bat for pitchers, providing early data on its feasibility. The tested it more extensively, with positive feedback on offensive output, while the used a variant allowing substitutions only after the pitcher's third at-bat. Further evaluation occurred in the 1973 at Royals Stadium in Kansas City, an venue, marking the first use of the rule in a major exhibition contest and showcasing its potential to add excitement without altering defensive strategies. These trials, supported by President —who advocated for the rule as a means to modernize the game and boost attendance—laid the groundwork for formal adoption. On January 11, 1973, owners approved the designated hitter rule by an 8-4 vote, implementing it for the upcoming season as a three-year experiment to differentiate from the , which rejected it to preserve traditional strategies involving pitcher hitting. The rule debuted on , April 6, 1973, when Yankees first baseman stepped to the plate as the first official designated hitter against the Boston Red Sox at ; Blomberg drew a walk in his initial at-bat, becoming an instant symbol of the innovation. Cronin's advocacy was pivotal, as he viewed the rule as essential for countering the league's offensive struggles, though traditionalists argued it undermined baseball's strategic balance. The primary motivations for adoption included addressing chronically low-scoring games—American League teams averaged just 3.47 runs per game in 1972—increasing fan interest through more hitting action, and minimizing pitcher injuries from batting duties, which were seen as unnecessary risks for specialists focused on pitching. Post-implementation, the rule delivered an immediate offensive surge: runs per game rose to 4.28 in 1973, a 23% increase, while batting averages climbed from .239 to .248, outpacing the National League's more modest gains and validating the experiment's intent to revitalize play.

Expansion and Universal Implementation

The introduction of interleague play in 1997 marked the first regular-season expansion of the designated hitter (DH) rule beyond (AL) parks, where it was used exclusively during AL home games, while (NL) pitchers were required to bat in NL home games. This "when in Rome" approach also applied to postseason play, including the from 1986 to 2021, where the DH was permitted only in AL ballparks, and exhibitions like the followed similar league-based conventions. The disparity created strategic adjustments for teams, with AL clubs preparing pitchers to hit during NL visits and NL teams leveraging the DH advantage on the road. The accelerated experimentation with a universal DH in 2020, when (MLB) implemented it league-wide for the shortened 60-game season as part of health and safety protocols to reduce player exposure to injury and virus transmission during at-bats and base running. In 2021, despite ongoing pandemic concerns, MLB and the MLB Players Association reverted to the traditional rules, with the DH limited to games and NL pitchers batting, though health protocols included measures like seven-inning doubleheaders to mitigate risks without extending the DH universally. The push for permanence culminated in the 2022 collective bargaining agreement (CBA) between MLB and the MLB Players Association, which adopted the universal DH rule effective for the entire season, eliminating NL pitcher batting and standardizing lineups across both leagues to enhance offensive balance and player safety. This change, ratified on March 10, 2022, followed months of negotiations amid the league's lockout and built on the 2020 trial's perceived benefits. Since 2022, the universal DH has remained in place without reversal as of 2025, applying to all regular-season, postseason, and games, with minor clarifications like the "Ohtani Rule" for two-way players but no broader alterations to . MLB's has prompted discussions in international organizations, influencing alignments in events like the to mirror the universal standard for consistency.

Strategic Impact and Debate

Advantages of the Designated Hitter

The introduction of the designated hitter (DH) rule in (MLB) has significantly boosted offensive production by replacing pitchers, who typically have low s, with specialized hitters capable of generating more runs and hits. Following the American League's (AL) adoption of the DH in 1973, the league's composite increased by 20 points, and runs per game rose by nearly one full run compared to the prior season. This offensive edge persisted historically, with the AL outscoring the (NL) due to the rule's impact on lineup construction. With the universal DH implemented in 2022, the NL experienced a comparable uplift, achieving a higher runs-per-game average than the AL for the first time since 1972, as the rule eliminated weak pitcher at-bats and integrated stronger hitters into every lineup. The DH rule enhances player safety, particularly for pitchers, by removing the physical demands of batting and baserunning, which can lead to injuries. A analyzing MLB injury data from 2021 (pre-implementation) and 2022 (post-implementation) found that the universal DH correlated with a significant reduction in pitcher injury incidence rates, dropping from 6.58 to 5.60 injuries per 1,000 athlete game-exposures overall (P = .02), and from 7.62 to 6.26 in the NL (P = .04). This decrease is attributed to pitchers avoiding the strains, fractures, and other risks associated with offensive duties, allowing them to focus solely on pitching and recovery. In terms of , the DH promotes excitement and strategic depth by fostering higher-scoring contests and expanding managerial options, such as more frequent and effective pinch-hitting without compromising the pitching staff. The rule's emphasis on offense has been linked to improved fan engagement, with surveys indicating broad support for its adoption; for instance, 56% of MLB fans polled in 2020 favored the DH across both leagues, citing its role in creating more dynamic at-bats and reducing the frequency of automatic outs from pitchers. Additionally, the DH has increased pinch-hitting opportunities, with league-wide rates rising notably in 2023 compared to 2022, enabling teams to optimize matchups and add tactical layers to games. The DH facilitates player , enabling elite hitters to maximize their contributions without the physical toll of fielding, thereby extending careers and enhancing overall team performance. Players like , who amassed 541 home runs primarily as a DH for the Boston Red Sox, exemplify how the role allows power hitters with limited defensive skills to remain productive contributors in lineups. This specialization aligns with modern baseball's analytics-driven approach, where teams prioritize offensive output from dedicated roles to construct balanced, high-impact rosters. Economically, the DH has positively influenced MLB by delivering the offensive excitement that draws spectators. using a difference-in-differences analysis of NL teams post-universal DH shows that the added offense from designated hitters increased by 3.5% to 7.9%, reflecting fans' preference for games with more scoring opportunities. This boost in turnout, observed consistently in the AL since 1973 and extended league-wide after 2022, underscores the rule's role in sustaining revenue through heightened entertainment value.

Criticisms and Traditionalist Views

The designated hitter (DH) rule has faced longstanding opposition from baseball traditionalists, who view it as a gimmick that undermines the sport's fundamental symmetry of nine players each contributing to both offense and defense. Critics, including former president , dismissed the DH as an unnecessary innovation that disrupted 's traditional balance, arguing it prioritized spectacle over the game's inherent strategy and purity. This perspective echoed broader purist sentiments that the rule eroded the integrity of by allowing specialization at the expense of well-rounded play, a concern prominent since the American League's adoption in 1973. Opponents further contend that the DH dilutes strategic depth by eliminating the need for pitchers to bat, thereby removing key tactical elements such as bunting, sacrifice flies, and the double switch—a where managers substitute two players simultaneously to optimize lineup positions. In pre-2022 National League games, these elements added layers of decision-making, as managers weighed when to pinch-hit for a pitcher or adjust the batting order mid-inning, fostering a chess-like quality absent in American League contests. For instance, iconic NL managers like frequently employed double switches to extend innings or protect relievers, tactics rendered obsolete under the universal DH. Prior to 2022, the rule's uneven application created a two-tiered system between the leagues, complicating talent evaluation and raising questions of fairness in and the . American League teams could roster pure hitters without defensive demands, potentially inflating offensive output and giving an edge in matchups against squads reliant on pitcher-hitting, which often depressed lineup averages. This disparity affected player development, as prospects in the had to hone hitting skills while counterparts focused solely on power, skewing free-agent markets and postseason equity—particularly in games played in neutral or venues where DH rules applied inconsistently. Some critics counter pro-DH health arguments by claiming the rule fosters over-specialization, potentially leading to weaker overall among pitchers who avoid batting-related physical demands, though on injury rates remains mixed. Minor studies suggest that while the DH may reduce hand and injuries from swings, it could indirectly contribute to strain by encouraging pitchers to throw harder without the deterrent of facing retaliation at the plate. For example, research indicates pitchers historically plunked opponents at higher rates post-DH adoption, possibly straining arms through escalated velocity. Even after universal implementation in 2022, resistance persists among fans and analysts, with petitions urging MLB to revert the to traditional rules, citing diminished strategic intrigue and a homogenization of the sport. Online campaigns, such as those on calling to "banish the universal DH," have garnered thousands of signatures, reflecting ongoing traditionalist backlash, though no reversals have occurred as of 2025. Some analysts have argued the rule has not sustained the expected long-term boost to offense, with MLB averaging 4.45 runs per game in 2025—comparable to pre-universal DH eras—amid influences like the and other rule changes.

Awards and Notable Figures

Designated Hitter Awards

The Outstanding Designated Hitter Award, originally established in 1973 as the American League's recognition for the top offensive performer among designated hitters, was renamed in 2004 to honor Mariners legend , who won it five times (1995, 1997, 2000–2002). The award evaluates players based on key offensive statistics such as , home runs, runs batted in (RBIs), , and overall consistency throughout the season, with voting conducted by the (BBWAA). holds the record with eight wins (2003–2007, 2011, 2013, 2016), followed by Martínez's five; other multiple winners include (five times, 2021–2025) and (three times). Prior to the 2022 adoption of the universal designated hitter rule, the award was exclusive to the , with no direct equivalent in the where pitchers batted; post-2022, it expanded to recognize the top DH across , integrating performers into eligibility and broadening considerations in broader honors like voting. The for designated hitter, introduced in 1980 as part of the broader Silver Slugger program honoring the best offensive players at each position, is voted on annually by managers and coaches who name one recipient per league based on performance metrics like , , and power production (home runs and RBIs), excluding players from their own teams. In the , won it seven times (2004–2007, 2011, 2013, 2016), emphasizing his dominance in extra-base hits and run production; notable winners post-universal DH include (2020), (2023), and (2024, 2025). The award highlights the DH's specialized role in boosting team offense without defensive responsibilities. The designated hitter position has featured prominently in Games since 1973, when the first utilized the rule to allow a dedicated batter in place of the , adding a slot specifically for DH selections voted by fans, players, and media. This innovation increased offensive firepower in midsummer classics, with DHs like (10 selections, including starting in 2013) and (7 selections) delivering iconic moments, such as Ortiz's game-tying in the 2013 at . Following the 2022 universal DH, the position became available in lineups as well, leading to more balanced representation and selections like Ohtani (multiple starts as DH) who showcased the role's impact on high-stakes exhibitions. Among statistical benchmarks recognizing DH excellence, David Ortiz stands as the all-time leader with 485 home runs hit as a designated hitter, a mark that underscores the position's potential for sustained power output over a career spanning 1997–2016. He also amassed 1,569 RBIs as a designated hitter, establishing a benchmark for run production that highlights the role's contribution to team scoring without fielding demands. Other leaders include Frank Thomas (296 home runs as DH) and Nelson Cruz (255), illustrating how elite DHs have shaped offensive records since the rule's inception.

Hall of Fame and Legendary Designated Hitters

The designated hitter position has produced several Baseball Hall of Famers whose careers were significantly shaped by the role, allowing them to contribute offensively without the physical demands of fielding. Frank Thomas, known as "The Big Hurt," was inducted in 2014 after a 19-year career primarily with the Chicago White Sox, where he played 57% of his 2,325 games as a DH or first baseman, amassing 521 home runs and two American League MVP awards. David Ortiz, nicknamed "Big Papi," became the first primary DH elected on his first ballot in 2022, following a 20-year tenure with the Boston Red Sox that included 541 home runs, three World Series titles, and 10 All-Star selections, with 2,028 of his 2,208 regular-season games at DH. Edgar Martínez, a Seattle Mariners icon, was inducted in 2019 after spending 71% of his 2,055 games as DH over 18 seasons, batting .312 with 309 home runs and earning five Silver Slugger awards despite early injuries limiting his third-base play. These inductions highlight the historical challenges faced by DH specialists in Hall of Fame voting, where traditionalists often undervalued players without defensive contributions, leading to prolonged waits or lower vote percentages. , for instance, received just 36.2% in his first year on the ballot in but climbed to 85.4% by , overcoming the "DH " that questioned the completeness of non-fielders' resumes. Similarly, , inducted in 2004 as the first player listed primarily as a DH, played approximately 40% of his 2,683 games in the role across three teams, finishing with 3,319 hits, 234 home runs, and a .306 average that underscored his versatility as a hitter. , elected via the Today's Game Era Committee in , logged 1,643 games—his most at any position—as a part-time DH over 22 seasons, retiring with 384 home runs and 2,866 hits that extended his longevity after injuries. Iconic moments define these players' legacies, illustrating the DH's evolution from a utility spot for aging stars in 1973 to a platform for offensive stardom by the 2000s. Ortiz epitomized this shift with his 2016 World Series heroics as Boston's DH, batting .688 (11-for-16) with three home runs and 10 RBIs over six games to earn MVP honors and cap his career with a third championship. Martínez's consistent excellence, including a .933 OPS and 147 OPS+ over his career, helped legitimize the DH as a core lineup fixture rather than a mere pinch-hitter substitute. Collectively, these Hall of Famers hit over 1,900 home runs—Thomas (521), Ortiz (541), Martínez (309), Baines (384), and Molitor (234)—demonstrating the position's power potential and influence on game strategy. As the universal DH rule took effect in 2022, modern players continue this legacy, with potential future inductees like , who transitioned to DH for 143 of his final 287 games from 2021-2023 due to injuries, ending a 21-year career with 511 home runs, 3,174 hits, and two awards that position him as a first-ballot lock in 2028. The role's growth from experimental addition to essential offensive weapon has enabled such transitions, ensuring DHs remain central to baseball's narrative of excellence.

Usage Outside Major League Baseball

Nippon Professional Baseball

The designated hitter (DH) rule was first adopted in Nippon Professional Baseball (NPB) by the Pacific League in 1975, two years after its implementation in Major League Baseball's American League, allowing teams to designate a batter to hit in place of the pitcher. The Central League, however, maintained its traditional format without the DH for the next five decades, preserving pitcher batting as a core element of strategy until August 2025, when league owners unanimously approved its introduction starting in the 2027 season to standardize rules across NPB. This adoption also incorporates provisions for two-way players, such as permitting a pitcher who has batted to continue as the DH after being removed from pitching, mirroring recent MLB adjustments. In the , where the rule has been in effect since 1975, the DH is assigned specifically to the and functions similarly to its MLB counterpart, enabling offensive specialization without requiring the designated player to field. Key variations from MLB include NPB's allowance for ties after 12 innings in regular-season games and a 28-player active roster, which provides greater flexibility for substitutions involving the DH compared to MLB's stricter limits. follows the home team's rules, so home games use the DH while home games do not, creating strategic contrasts. The DH has significantly boosted offensive production in the , contributing to NPB's reputation for high-scoring games by removing weaker-hitting pitchers from the lineup and allowing managers to deploy power hitters full-time, which proponents argue enhances excitement and pitcher focus. Notable examples include sluggers like , who thrived as a and DH with over 2,000 hits and 1,000 RBIs across his career, exemplifying how the rule elevated dedicated hitters in the league. This offensive emphasis has been evident in teams' higher run totals compared to the pitcher-hitting , underscoring the rule's impact on game dynamics. A key difference from MLB lies in NPB's historical emphasis on pitcher hitting during cross-league exhibitions, such as the , where rules traditionally applied without a DH until the 2026 series—the last under the old format—allowing pitchers to bat and adding a layer of strategic depth absent in MLB's universal DH era. As of November 2025, no further universal changes have occurred beyond the planned 2027 adoption, though discussions highlighted benefits like for pitchers and alignment with global standards. Culturally, the DH in the has played a pivotal in fostering , attracting MLB veterans as sluggers who fill the to extend careers or rebuild value, such as sluggers like , who set NPB single-season records as an and later contributed in the DH-enabled with the . This integration supports NPB's , enabling seamless transitions for top players to MLB while importing expertise that elevates competition and fan interest in bilateral player movement.

Mexican League and Winter Leagues

The Mexican League (LMB), Mexico's premier professional baseball circuit, has employed the designated hitter (DH) rule in all games since the 1970s, predating its universal adoption in Major League Baseball by nearly five decades. This implementation aligns with the league's emphasis on offensive production, particularly in high-altitude venues like Estadio Alfredo Harp Helú in Mexico City (elevated at approximately 7,350 feet), where thinner air facilitates greater ball carry and rewards power hitting. By allowing a dedicated batter to replace the pitcher, the DH enables teams to optimize lineups with stronger hitters, contributing to elevated home run rates observed in LMB play compared to sea-level parks. In the LMB, the DH adheres to standard professional rules, batting exclusively in place of the without defensive responsibilities, which supports scout compatibility with MLB standards. This setup has fostered the development of power-oriented players suited to the league's environmental conditions, where the DH slot often features sluggers who thrive on the altitude advantage. As of , the remains fully integrated, aiding MLB free agents and prospects in maintaining offensive sharpness during off-seasons through LMB participation. Caribbean winter leagues, including the Liga de Béisbol Profesional de la República Dominicana (LIDOM) and Liga Venezolana de Béisbol Profesional (LVBP), incorporated the DH variably starting in the 1970s, influenced by MLB's experiment, and now apply it universally in regular-season, playoff, and international contests like the . These leagues mirror MLB's DH guidelines to facilitate talent evaluation by scouts, ensuring pitchers focus on defense while a specialized hitter bolsters the offense. In playoffs and the , the DH has proven pivotal, enabling strategic flexibility for aging stars or power specialists. Notable examples include veteran slugger , who transitioned to a primary DH role in the LVBP during the 2025-26 season with , leveraging the position to extend his career while preparing for potential MLB return. Similarly, in the 2025 —won by LIDOM's over Mexico's Charros de —the DH contributed to Dominican offensive dominance, with players like reinforcing the lineup in limited at-bats. By 2025, full DH adoption across these winter circuits has solidified their role in player development, allowing free agents to refine hitting mechanics in competitive environments akin to MLB.

Minor League and Amateur Baseball

In (MiLB), the designated hitter (DH) rule has been used since its trial in the in 1969, with universal implementation across all levels by the 1970s, applying to all games regardless of the affiliations of the competing teams. This includes matchups between (AL) affiliates, (NL) affiliates, or mixed AL-NL games, allowing a tenth player to bat in place of the pitcher without affecting the pitcher's defensive role. The rule aligns with MLB's Official Baseball Rules (Rule 5.11), permitting the DH to be designated prior to the game and to bat in any spot in the lineup. In amateur baseball, the DH rule varies by governing body but is widely adopted to accommodate player development and game pace. Under (NCAA) rules, the DH is a player designated to bat exclusively for the and all subsequent s, creating a potential 10-player lineup; the DH's spot is fixed pre-game, and substitutions must maintain the role's integrity, such as allowing the pitcher to become the DH only under specific pinch-hitting conditions. This setup emphasizes offensive specialization while preserving pitching focus, though teams may opt for a nine-player lineup where the pitcher also serves as the DH (P/DH). High school , governed by the National Federation of State High School Associations (NFHS), expanded the DH rule in 2020 to offer greater flexibility, allowing the DH to bat for any starting defensive player (not just the ) and permitting a "Player/DH" designation where one athlete fills both roles simultaneously. In this expanded format, the Player/DH can be substituted defensively while retaining the DH batting spot, but the role terminates if the DH is replaced offensively or if the player for whom the DH bats enters the game offensively; this change aims to maximize participation and strategic options without altering the nine-defensive-player structure. In youth leagues like , the DH is permitted only in the Senior Division (ages 13-16) during tournament play, where it functions similarly to MLB rules by allowing a tenth batter for the pitcher, with re-entry options for starting players including the DH. Younger divisions, such as Majors (ages 9-12), typically use a continuous batting order with all rostered players hitting, eschewing the DH to promote well-rounded skill development. Other amateur circuits, such as , generally follow NCAA or NFHS guidelines, incorporating the DH to align with professional pathways while adapting for age-appropriate play.
