Jasson Domínguez Bio
Jasson Domínguez González, nicknamed El Marciano or The Martian, is a Dominican professional baseball outfielder for the New York Yankees of Major League Baseball. He signed with the Yankees as an international free agent in 2019 and made his major league debut on September 1, 2023. Wearing jersey number 24, he plays all three outfield positions and bats from both sides of the plate.
Widely regarded as a five-tool player, Domínguez became one of the most celebrated international prospects in recent Yankees history. He set a franchise record with his $5.1 million signing bonus and reached the majors at age 20.
Early Life and Background
Jasson Domínguez González was born in Esperanza, a municipality in the Valverde Province of the Dominican Republic, on February 7, 2003. He is the second of six children born to Félix Domínguez and Dorca González. His father, a former baseball player and longtime New York Yankees fan, named his son after Yankees first baseman Jason Giambi.
Domínguez began training for a baseball career at age eight. At 13, he signed with trainer Iván Noboa, who helped shape his early development. Originally a catcher, he later transitioned to center field, where his speed and arm strength became defining traits.
During his teenage years, viral workout videos of Domínguez circulated on social media, drawing comparisons to Mickey Mantle, Bo Jackson, and Mike Trout. It was during this period that a trainer reportedly nicknamed him El Marciano, Spanish for The Martian, because his talent seemed otherworldly.
Path to Professional Baseball
MLB.com ranked Domínguez as the top prospect eligible to sign in the 2019–2020 international class. On July 2, 2019, the Yankees signed him for a franchise-record $5.1 million bonus, receiving the majority of the club’s $5.4 million total international allotment for the year.
He did not play in 2020 after the minor league season was canceled because of the COVID-19 pandemic. Domínguez instead trained at a baseball academy in Santiago, Dominican Republic, working on his conditioning and mechanics while he waited for organized games to resume.
Domínguez made his professional debut in June 2021 with the Florida Complex League Yankees. Later that summer, he was chosen for the All-Star Futures Game, becoming the first prospect to appear in the showcase without first playing a full minor league season. The Yankees promoted him to the Tampa Tarpons of the Low-A Southeast League after the Futures Game.

Minor League Development (2021–2023)
Domínguez opened the 2022 season with Tampa and earned a second straight All-Star Futures Game invitation, this time at Dodger Stadium. After the showcase, the Yankees promoted him to the Hudson Valley Renegades of the High-A South Atlantic League. When Hudson Valley’s season ended, Domínguez was promoted to the Somerset Patriots of the Double-A Eastern League for the final regular-season games and the postseason.
In 2023, the Yankees invited Domínguez to major league spring training as a non-roster player before assigning him to Somerset to begin the year. He earned promotion to the Scranton/Wilkes-Barre RailRiders of the Triple-A International League on August 22, and won the Eastern League Top MLB Prospect Award after the season.
MLB Debut and Rookie Impact (2023)
The Yankees promoted Domínguez to the major leagues on September 1, 2023, and he debuted that night against the Houston Astros. In his first major league at bat, Domínguez homered off Justin Verlander, becoming the youngest player in Yankees history to homer in his debut and the fifth youngest in MLB history to homer on his first plate appearance. He hit four home runs in eight games before a torn ulnar collateral ligament in his right elbow ended his season on September 10 and required Tommy John surgery.
Return and Breakout Moments (2024–2025)
Domínguez began the 2024 season on the 60-day injured list, continuing his recovery from elbow surgery. After a rehabilitation assignment in May, the Yankees activated and optioned him to Scranton/Wilkes-Barre on June 12. An oblique strain later that month delayed his return until late July. The Yankees recalled him on September 9, 2024, though he batted .179 in 56 at bats and struggled defensively in left field.
On May 9, 2025, Domínguez became the youngest player in Yankees history to hit three home runs in a single game, doing so against the Athletics at their temporary home in Sacramento. He went 3-for-4 with seven runs batted in, including a grand slam batting left-handed, marking one of the rare switch-hit, three-homer games with a grand slam in Major League history. On May 21, 2025, he delivered his first major league walk-off home run off Texas Rangers pitcher Luke Jackson to give the Yankees a 4–3 victory, the club’s first walk-off homer since 2022.
Driving Style and Strengths
Domínguez is a switch hitter whose power plays to all fields, and he profiles as a true five-tool player with above-average speed, a strong throwing arm, and developing on-base skills. He has shown a willingness to use the entire field from both sides of the plate, and his athleticism allows him to play center field, left field, and right field comfortably. His aggressive base running and improving plate discipline have made him a multi-dimensional threat in the Yankees’ lineup.
Notable Events and Milestones
Beyond his historic debut homer, Domínguez’s signature moments include his 2025 three-homer game against the Athletics, his first career walk-off home run in May 2025, and his franchise-record $5.1 million signing bonus in 2019. He also became the first prospect to appear in the All-Star Futures Game without a prior full-season minor league assignment, doing so in 2021.
