Mark Anthony Vientos, nicknamed "Swaggy V," is a Major League Baseball player for the New York Mets, playing primarily as a third baseman, designated hitter, and first baseman. Born on December 11, 1999, in Norwalk, Connecticut, to parents from Nicaragua and the Dominican Republic, he was selected by the Mets in the second round of the 2017 MLB Draft and signed for a $1.5 million bonus. After a standout minor league career—including being named the Mets' Minor League Hitter of the Year in 2019—he overcame the COVID-canceled 2020 season and hit 22 home runs in 2021, leading to his promotion to the 40-man roster. Vientos made his MLB debut on September 11, 2022, against the Miami Marlins, and later that month hit his first career home run against the Oakland Athletics, also representing the Mets at the 2022 All-Star Futures Game. In 2023, after dominating Triple-A with 13 home runs and a 1.104 OPS, he was called up on May 17 to spark a struggling offense, hitting a game-tying home run in his first start that night against the Tampa Bay Rays. His energetic playing style and "swagger" draw comparisons to role models Alex Rodriguez and Manny Machado, though he grew up idolizing former Mets captain David Wright.
