Anthony Seigler Bio
Anthony Seigler (born June 20, 1999) is an American professional baseball catcher and infielder. He currently plays in Major League Baseball (MLB) for the Boston Red Sox, having previously appeared in the majors with the Milwaukee Brewers. A switch-hitter and a former switch pitcher, Seigler is recognized for his positional versatility and his ability to play several roles on the diamond.
Originally drafted by the New York Yankees in the first round of the 2018 MLB Draft, Seigler rose steadily through the minor leagues before reaching the major leagues in 2025. He became only the second player of Navajo heritage to play in the majors, following Jacoby Ellsbury.
Early Life and Background
Anthony Seigler was born on June 20, 1999, in Cartersville, Georgia, in the United States. He grew up in Cartersville and attended Cartersville High School, where he developed into a multi-dimensional baseball talent. From an early age, Seigler trained as both a hitter and a pitcher, becoming a switch hitter and a switch pitcher who could throw and bat from either side of the plate.
His father, who had played college baseball and later taught Spanish at Cartersville High School, played a major role in shaping his athletic development. To support his son’s ambidextrous approach, Seigler’s father purchased both a right-handed and a left-handed glove, encouraging him to become a switch-thrower. He was also named after Major League Baseball player Tony Phillips, a friend of his father who had briefly lived in the Seigler household.
Path to Baseball
Seigler emerged as one of the most intriguing prospects in the 2018 draft class because of his rare versatility. During his senior year at Cartersville High School, he batted .421 with 14 home runs, while also posting a 1.09 earned run average (ERA) with 29 strikeouts in 25 and two-thirds innings on the mound. That performance led him to commit to play college baseball at the University of Florida for the Florida Gators.
Before turning professional, Seigler represented the United States at the 2017 U-18 Baseball World Cup in Thunder Bay, Canada, where he served as a catcher. He batted .182 in seven games as Team USA went undefeated and won the gold medal. Shortly after the tournament, the New York Yankees selected him with the 23rd overall pick in the 2018 MLB Draft. He signed with the team on June 9, 2018, for a slot-valued bonus of $2.8 million, choosing professional baseball over his college commitment.
Anthony Seigler Career
Early Career (2018–2019)
Seigler began his professional career in 2018 with the rookie-level Gulf Coast League Yankees. After 12 games, the Yankees promoted him to the advanced rookie-level Pulaski Yankees, where he played another 12 games. Between the two clubs, he batted .266 with one home run and nine runs batted in (RBI), showing a strong offensive foundation in his debut season.
In 2019, he advanced to the Single-A Charleston RiverDogs but struggled at the plate, batting .175 with six RBI over 30 games. The season was also interrupted by injuries, as a quadriceps strain delayed his start and a knee fracture suffered while catching ended his campaign nearly two months early. He did not appear in a game in 2020 after the minor league season was canceled because of the COVID-19 pandemic.
Yankees System and Position Change (2021–2024)
Seigler returned to action in 2021 with the High-A Hudson Valley Renegades. Limited to 41 games because of injuries, he slashed .219/.324/.391 with four home runs and 24 RBI. During that season, he made his first professional appearance as an outfielder, throwing with his left hand.
In 2022, he split the year between Hudson Valley and the Single-A Tampa Tarpons, playing 97 games and batting .236/.405/.369 with seven home runs, 45 RBI, and 16 stolen bases. The following year, Seigler moved up to the Double-A Somerset Patriots, where he began playing second base in addition to catching. In 67 games, he slashed .166/.333/.263 with five home runs, 27 RBI, and seven stolen bases. Returning to Somerset in 2024, he played exclusively at second base and produced his strongest statistical year in the Yankees system, slashing .234/.350/.398 with 12 home runs, 49 RBI, and a team-leading 29 stolen bases over 118 games. He elected free agency on November 4, 2024.
Milwaukee Brewers Era (2025)
On November 19, 2024, Seigler signed a minor league contract with the Milwaukee Brewers. He opened the 2025 season with the Triple-A Nashville Sounds, playing both catcher and second base. In 63 Triple-A games, he batted .277/.416/.465 with seven home runs, 35 RBI, and 20 stolen bases, marking his best offensive stretch since 2018. During this period, he also began hitting left-handed against left-handed pitchers, choosing to forgo the traditional platoon advantage.
On July 1, 2025, the Brewers added Seigler to their 40-man roster and promoted him to the major leagues. He made his MLB debut the following day, starting at third base for both games of a doubleheader, and recorded his first major league hit in the sixth inning of the second game, a single off Dedniel Núñez of the New York Mets. Across 34 appearances with Milwaukee, he slashed .194/.292/.210 with five RBI and two stolen bases, and he was selected to the 26-man roster for the 2025 National League Division Series against the Chicago Cubs.
Driving Style and Strengths
Seigler’s value comes from his positional versatility, his switch-hitting ability, and his baserunning instincts. He can catch, play second base, third base, and the outfield, and he has even shown the ability to throw left-handed in the field. That flexibility, combined with above-average speed and a patient approach at the plate, makes him a useful utility player for managers looking for roster flexibility.
Notable Events and Milestones
His MLB debut on July 2, 2025, marked the realization of a years-long journey through the minor leagues after being a first-round pick in 2018. He also became the second player of Navajo heritage to play in Major League Baseball, following outfielder Jacoby Ellsbury, a milestone that added historical significance to his first game.

2025 Season Performance
The 2025 season represented a breakthrough for Anthony Seigler, who spent the year with the Milwaukee Brewers organization. He began the campaign at Triple-A Nashville, where his .277/.416/.465 batting line, seven home runs, 35 RBI, and 20 stolen bases over 63 games stood out as the best offensive stretch of his professional career. The Brewers rewarded that production by selecting his contract on July 1.
After his July 2 MLB debut, Seigler appeared in 34 games for Milwaukee, providing depth at catcher, second base, and third base while adjusting to major league pitching. He finished his rookie regular season slashing .194/.292/.210 with five RBI and two stolen bases, and he was later included on the Brewers’ 26-man roster for the 2025 National League Division Series against the Chicago Cubs.
