Mark Vientos
Mark Vientos is an American professional baseball third baseman for the New York Mets of Major League Baseball (MLB).[1] Born on December 11, 1999, in Norwalk, Connecticut, he was selected by the Mets in the second round (59th overall) of the 2017 MLB Draft out of American Heritage High School in Plantation, Florida, signing for a $1.5 million bonus as a bat-first shortstop prospect.[1][2][3] Vientos progressed through the Mets' minor league system, primarily at third base after transitioning from shortstop, and made his MLB debut on September 11, 2022, against the Miami Marlins at age 22.[2][4] In his early major league appearances (2022–2023), he batted .211 with 9 home runs across 233 plate appearances, splitting time between the majors and Triple-A Syracuse.[5] Vientos emerged as a breakout star in the 2024 season, posting a .266 batting average with 27 home runs, 71 RBIs, and an .838 OPS in 454 plate appearances, contributing significantly to the Mets' wild card berth and playoff run.[5][6] During the 2024 postseason, he set Mets single-postseason records with 14 RBIs and seven multi-hit games across 10 contests, batting .327 with 5 home runs and 18 hits while tying for second on the team in total bases (36); notable moments included a grand slam in Game 2 of the NLCS against the Los Angeles Dodgers.[1][7][8] In 2025, Vientos appeared in 463 plate appearances for the Mets, slashing .233/.289/.413 with 17 home runs and 61 RBIs, while also providing defensive versatility at first base and as a designated hitter.[5][6] Standing at 6 feet 3 inches and weighing 185 pounds, Vientos bats and throws right-handed and is known for his power potential and clutch hitting.[1][2]Early life and amateur career
Early life
Mark Vientos was born on December 11, 1999, in Norwalk, Connecticut.[9] His family heritage reflects a multicultural background, with his father, Charles Manuel Vientos, originating from the Dominican Republic before immigrating to New York as a child, and his mother, Katy (or Kelly) Wilmor, born in Nicaragua.[10][11] This Dominican paternal lineage later contributed to his eligibility for international play.[10] At a young age, Vientos moved with his family to Miami, Florida, where he spent much of his early childhood.[10] Growing up in this environment, he developed an early passion for baseball, influenced heavily by his father's enthusiasm for the sport and fandom of the New York Mets, stemming from his own experiences in New York.[12] Vientos' initial youth experiences included watching Mets games at home and collecting cards of players like David Wright, fostering his foundational interest in the game amid Florida's competitive baseball scene.[12] The relocation to Florida provided Vientos with greater access to year-round training and local youth leagues, enhancing his early skill development in a region known for producing baseball talent.[10]High school career
Vientos attended Charles W. Flanagan High School in Pembroke Pines, Florida, for his first three years of high school, where he played as a shortstop and third baseman. During his junior season in 2016, he helped lead the Falcons to a 17-5-1 overall record and an undefeated 8-0 district mark, securing the district championship.[13][14] That year, Vientos was selected to the 2015-16 All-USA Florida Baseball Team as an infielder, recognizing his standout performance among the state's top prospects. He also participated in the National High School Invitational tournament with Flanagan, showcasing his skills against elite competition from across the country.[15][16] Prior to his junior year, Vientos committed to play college baseball for the University of Miami Hurricanes in August 2014, drawn to the program's prestige and proximity to home. However, seeking greater exposure ahead of the MLB Draft, he transferred to American Heritage High School in Plantation, Florida, for his senior year in 2016-17. At American Heritage, Vientos batted .417 with a .467 on-base percentage over 26 games, scoring 26 runs and recording 35 hits despite being limited by a quadriceps injury. His performance earned him spots on the 2017 MaxPreps Medium Schools All-American Baseball Team and the broader High School Baseball All-American Teams, highlighting his power potential and athleticism. The Patriots advanced to the Class 4A state semifinals that season, falling just short of the championship game.[17][18][19][20][21] Throughout his high school career, Vientos gained national attention through prestigious showcases, including the Perfect Game All-American Classic at Petco Park during the summer following his junior year. These events, combined with his consistent production and physical tools—standing 6-foot-4 with a projectable frame—drew scouting interest and solidified his status as a top draft prospect, ultimately leading him to forgo his college commitment in favor of professional baseball.[22][23]MLB draft
Vientos was selected by the New York Mets in the second round, 59th overall, of the 2017 Major League Baseball Draft out of American Heritage High School in Plantation, Florida.[24] His standout high school performance, including a .412 batting average and 11 home runs as a senior, elevated his draft stock as a power-hitting infielder.[25] Despite a verbal commitment to play college baseball for the University of Miami, Vientos opted to turn professional upon being drafted.[26] The Mets signed him to a minor league contract on June 20, 2017, for a signing bonus of $1.5 million, exceeding the slot value recommendation of $1,094,700 by approximately $405,300.[23] Following the signing, Vientos received his initial professional assignment to the Gulf Coast League Mets, the team's rookie-level affiliate.[27] At 17 years old, he was among the youngest players in the 2017 draft class.[16]Professional career
Minor league career
Vientos began his professional career in 2017 after being selected by the New York Mets in the second round of the MLB Draft. He made his debut with the Rookie-level Gulf Coast League (GCL) Mets, appearing in 47 games and batting .262 with 4 home runs and 26 RBIs. Late in the season, he was assigned to the Rookie-level Kingsport Mets of the Appalachian League for 4 games, marking his initial exposure to short-season play.[28][29] In 2018, Vientos spent his full rookie season with the Kingsport Mets in the Appalachian League, where he showed significant power potential at age 18, hitting .287 with 11 home runs and 52 RBIs over 60 games. This performance solidified his prospect status within the Mets organization. The following year, 2019, he advanced to full-season Class A ball with the Columbia Fireflies of the South Atlantic League, posting a .255 batting average with 12 home runs, 62 RBIs, and 27 doubles in 111 games—leading the team in several offensive categories. His breakout campaign earned him the Mets' Sterling Minor League Hitter of the Year award, as well as Baseball America's Mets Minor League Player of the Year honor, highlighting his rapid development as a power-hitting corner infielder.[28][30][31] The 2020 minor league season was canceled due to the COVID-19 pandemic, but Vientos remained active as part of the Mets' 60-player pool at their alternate training site in Brooklyn, where he focused on skill refinement without official games. Returning in 2021, the Mets aggressively promoted him to Double-A with the Binghamton Rumble Ponies of the Eastern League, skipping High-A entirely. In 72 games there, he batted .281 with 22 home runs and 59 RBIs, earning Double-A All-Star recognition and tying for fourth in the league in home runs. Later that year, he made his Triple-A debut with the Syracuse Mets in September, hitting .278 with 3 home runs in 11 games, demonstrating readiness for higher competition.[1][29][1] Vientos continued his progression at Triple-A Syracuse in 2022, batting .280 with 24 home runs and 72 RBIs in 101 games while earning International League All-Star honors. His consistent power output—leading Mets minor leaguers in home runs that season—underscored his growth into a top organizational prospect. In subsequent years, he split time between Syracuse and the majors, but his minor league stints in 2023 (.306 average, 16 home runs in 61 games), 2024 (.284, 6 home runs in 31 games), and early 2025 (.174 in 6 games) further honed his skills at the highest minor league level before additional call-ups.[32][28][29]Major league debut
Vientos was called up to the New York Mets' major league roster on September 11, 2022, as a corresponding move to outfielder Starling Marte's placement on the 10-day injured list due to a fractured right middle finger.[4] The 22-year-old infielder, ranked as the Mets' No. 7 prospect at the time, had spent the season with Triple-A Syracuse, where he hit .280 with 24 home runs in 101 games.[28] He made his major league debut that evening against the Miami Marlins at loanDepot park, starting as the designated hitter and batting eighth in the lineup.[4] Vientos went hitless in five at-bats during the Mets' 9-3 victory, striking out twice.[33] Four days later, on September 15 versus the Pittsburgh Pirates, he notched his first career hit—an RBI single to right field off reliever Yerry De Los Santos that drove in Francisco Lindor.[34] Vientos collected his first major league home run on September 24 at Citi Field against the Oakland Athletics, launching a solo shot to right-center off starter Ken Waldichuk in the second inning to tie the game at 4-4.[35] Over his limited 2022 stint of 16 games, primarily at third base with some designated hitter duties, he batted .167 (6-for-36) with one home run, three RBI, and five walks, while facing adjustment challenges evidenced by a 29.3% strikeout rate against major league pitching.[2]2023 and 2024 seasons
Vientos appeared in 65 games for the New York Mets during the 2023 season, primarily in a utility role after multiple call-ups from Triple-A Syracuse, where he batted .211 with nine home runs and 16 RBIs across 218 at-bats.[5] His first major league stint began on May 17, when he homered in his debut against the Tampa Bay Rays, but he was optioned back to the minors after nine games; subsequent recalls in July and September yielded inconsistent results, including a .192 average post-All-Star break, before a left wrist tendonitis injury sidelined him in August.[36] Overall, Vientos posted a .620 OPS and struck out in 31.7% of plate appearances, reflecting adjustment challenges against big-league pitching, though his raw power was evident with a 15.1% barrel rate.[5] Entering 2024, Vientos started in Triple-A, slashing .308/.385/.654 with six home runs in 17 games before his April 5 recall, during which he hit .320 with four homers in limited action; however, a May slump (.167 average) led to another demotion.[37] He returned permanently on June 1 following Brett Baty's demotion amid the third baseman's own struggles, transitioning into New York's primary third baseman for the remainder of the season and appearing in 125 games overall.[38] Vientos finished with a .266 batting average, 27 home runs, 71 RBIs, and an .838 OPS, ranking third among National League third basemen in OPS and contributing 3.1 WAR while posting a career-best 16.4% walk rate and 28.1% strikeout rate.[39] Notable performances included two solo home runs against the Yankees on June 25 in the Subway Series, helping secure a 9-7 victory, and a three-game hitting streak with four RBIs during a late-July series against the Athletics.[40] Defensively at third base, Vientos logged 880.1 innings with a .980 fielding percentage, six errors, and a -5 Defensive Runs Saved, showing marginal improvement in reaction time and arm strength from 2023 but remaining below league average per Outs Above Average (-4).[41] His baserunning advanced slightly, with zero stolen bases but positive runs on advances (1.2 UBR) and a 26.3 ft/s sprint speed that placed him in the 44th percentile, reflecting better decision-making on the bases compared to his rookie year.[5] In the 2024 postseason, Vientos excelled as the Mets advanced to the NLCS, batting .327 with five home runs and 14 RBIs over 13 games, establishing Mets single-postseason records for RBIs and multi-hit games (seven).[1] Highlights included a three-run homer in the NLDS clincher against the Phillies and a pivotal second-inning grand slam off Landon Knack in NLCS Game 2 versus the Dodgers, which propelled New York to a 7-3 win and evened the series at 1-1; he added two more homers in the series but went hitless in Games 6 and 7 as the Mets fell short.[42]2025 season
In 2025, Mark Vientos experienced a sophomore slump following his breakout 2024 campaign, posting a .233 batting average with 17 home runs and 61 RBIs over 121 games for the New York Mets.[43] His overall OPS+ of 97 marked him as a below-league-average hitter, a decline attributed in part to mechanical adjustments and injuries that disrupted his rhythm.[44] Vientos began the season with promise in the first half, hitting .250 with five home runs and a .740 OPS in 128 at-bats, but his performance dipped in the second half to .226 with 12 home runs and a .686 OPS across 296 at-bats.[45] Despite the overall regression, he showed clutch contributions late in the year, including key hits in high-leverage situations that helped stabilize the Mets' lineup during their push for the playoffs.[46] Injuries hampered Vientos throughout the season, starting with a minor groin strain in April that caused him to miss one game.[44] More significantly, he suffered a right hamstring strain on June 2 while running to first base against the Los Angeles Dodgers, leading to his placement on the 10-day injured list the following day; he missed most of June and began a rehab assignment with the Triple-A Syracuse Mets before returning on June 27.[47] Additionally, he exited a game on August 25 after being hit by a pitch and sat out four straight games around mid-August due to lingering effects.[48] Defensive concerns persisted at third base, prompting role experiments for Vientos, who appeared primarily as a designated hitter in the second half and logged 17 games at first base amid uncertainty surrounding Pete Alonso's future.[44] This versatility positioned him as a potential everyday option at first base or DH if Alonso departed in free agency, though his subpar glove work limited his infield starts.[49] As the season concluded, Vientos drew trade interest ahead of the July deadline, with the Mets opting to retain him rather than deal for a rental player, but offseason rumors persisted regarding a possible change of scenery to unlock his power potential elsewhere.[50] Analysts viewed his 2025 as a developmental setback, projecting a rebound in 2026 depending on his role and adjustments to plate discipline.[51]International career
Youth international play
Vientos represented the United States at the youth international level as a member of the 2014 USA Baseball 15U National Team, competing in the II WBSC U-15 Baseball World Cup held in Sinaloa, Mexico, from July 31 to August 10.[52][53] Playing primarily as an infielder, Vientos appeared in 10 games during the tournament, where he batted .324 with 11 hits in 34 at-bats, including one double, eight runs scored, and nine RBIs.[54] His on-base percentage reached .432, driven by eight walks, contributing to Team USA's strong offensive output en route to the gold medal final.[54] The United States advanced to the championship game but fell to Cuba, 6-3, securing a silver medal as runners-up in the eight-team competition.[55][56] This marked Vientos' only appearance for a USA Baseball youth national team prior to his professional draft.[57]Senior international eligibility
Mark Vientos, born in Norwalk, Connecticut, is eligible to represent the United States in senior international baseball competitions due to his birthplace.[58] He also holds eligibility for the Dominican Republic through his father, who was born in that country; Nicaragua via his mother, who was born there; and Puerto Rico because his paternal grandfather originated from Mayagüez.[58] In February 2025, Vientos committed to playing for the Dominican Republic in the 2026 World Baseball Classic, announcing his decision to the Federación Dominicana de Béisbol (FEDODEB) president Juan Núñez during spring training at Clover Park in Port St. Lucie, Florida.[59] This choice aligned with his expressed preference to honor his father's heritage, despite earlier youth representation for the United States at the under-15 level.[2] However, as of November 2025, recent reports indicate that his decision remains undecided, narrowed to representing either Nicaragua or Puerto Rico, amid ongoing recruitment efforts by both federations.[60][61] Vientos has not made any senior international appearances.[](https://worldbaseball.com/mark-vientos-commits-to-the-dominican-re Republic-for-the-2026-world-baseball-classic/)Playing style
Scouting grades
Prior to the 2017 MLB Draft, scouts evaluated Mark Vientos as a high-upside bat-first infielder with significant power potential from the right side. According to MLB Pipeline's initial prospect assessment shortly after his selection, Vientos received the following scouting grades on the 20-80 scale: hit 45, power 60, run 40, arm 60, field 50, and overall future value 50.[62] These grades highlighted his plus raw power and arm strength as carrying tools, while noting average contact ability and below-average speed and fielding as areas for development, projecting him as a potential average regular corner infielder.[62] Following his major league debut in 2022 and subsequent performance, scouting evaluations evolved to reflect his adaptation to big-league pitching. By 2024, evaluators adjusted his hit tool upward to around 50 due to improved plate discipline and contact rates, maintaining the 60 power grade while keeping run at 40; however, fielding grades dipped to 40 amid concerns over consistency at third base. Arm strength remained a plus at 55, supporting his viability at corner positions. His minor league progression, including power surges in Triple-A, contributed to these refinements by demonstrating translatable strength against advanced competition.[16] Vientos' profile draws comparisons to power-oriented corner infielders like Pete Alonso, emphasizing shared traits in raw power and right-handed swing mechanics, though scouts note Vientos' more projectable hit tool as a differentiator from Alonso's early-career profile.[63] Other parallels include players like Butch Huskey, highlighting Vientos' gap-to-gap approach with emerging over-the-fence pop suited for designated hitter or third base roles.[64]Offensive profile
Mark Vientos is a right-handed power hitter who exhibits a notable pull-side tendency in his batted ball profile, with approximately 45-50% of his contact directed to the pull side across his major league seasons.[5] This approach leverages his raw strength to generate extra-base hits, particularly against pitches over the inner half. His career slugging percentage reflects a clear progression in power output, improving from .367 in 2023 (over 233 plate appearances) to a breakout .516 in 2024, before regressing slightly to .413 in 2025 amid 463 plate appearances.[41][5] Vientos' plate discipline has been a point of focus throughout his career, characterized by high strikeout rates and modest walk totals. He posted a 29.5% strikeout rate in 2024 alongside a 7.5% walk rate, reflecting aggressive swinging and vulnerability to off-zone pitches.[41] Early in 2025, he showed improvement with a strikeout rate dipping to 23.5% through late May, but it settled at 24.8% for the full season, paired with a 6.5% walk rate, indicating ongoing challenges in pitch selection despite some refinement in chase rates around 33%.[65][41][5] A key adaptation in Vientos' hitting approach came in 2024, when he optimized his launch angle by reducing his ground ball rate to 44.2% from higher levels in prior years, which facilitated a surge in home runs to 27—his career high—and elevated his isolated power to .250.[66] This adjustment aligned with Statcast metrics showing a 14.1% barrel rate (92nd percentile), though both the barrel rate and home run output declined in 2025 to 11.5% and 17, respectively.[67] Advanced batted ball data underscores his power potential, with a 2025 average exit velocity of 91.4 mph and a 50.5% hard-hit rate, metrics that ranked in the upper tier despite the overall offensive dip.[5]Defensive skills
Vientos serves as the New York Mets' primary third baseman, where he exhibits above-average arm strength, graded as 60 on the standard 20-80 scouting scale, allowing him to make strong throws across the diamond. His defensive profile at the position features solid range for routine plays but has been hampered by inconsistencies in error prevention and overall efficiency, as reflected in advanced metrics. Over his MLB career through 2025, Vientos has appeared in 201 games at third base, logging 1,602.1 innings with a .964 fielding percentage on 450 total chances (109 putouts, 325 assists, 16 errors).[2] His Defensive Runs Saved (DRS) at third base totals -20, indicating below-average performance relative to league standards, while his career error rate of 3.6% highlights ongoing challenges with clean fielding.[2] The following table summarizes Vientos' key defensive statistics at third base across his major league seasons:| Season | Games | Innings | Chances | Putouts | Assists | Errors | Fielding % | DRS |
|---|---|---|---|---|---|---|---|---|
| 2022 | 2 | 13.0 | 2 | 0 | 2 | 0 | 1.000 | 0 |
