  • Roman Anthony is the youngest player during the 2025 season.
  • Anthony is 21 years old in his rookie campaign.

MLB teams continue to call up their prospects much earlier, so it’s important to keep track of the sport’s promising young players.

The youngest player in MLB history was Joe Nuxhall, who debuted in the MLB for the Cincinnati Reds on June 10, 1944, at 15 years of age. Nuxhallโ€™s extremely early major league selection was the exception rather than the rule, but there are still plenty of players proving that sometimes career success comes sooner rather than later.

*Note: all ages are as of June 30, which is the date MLB uses to determine a season age.

Who is the Youngest MLB Player in 2025?

Boston Red Sox outfielder Roman Anthony became the youngest MLB player during the 2025 season when he made his debut on June 9.

Anthony, who was drafted in the second round of the 2022 MLB draft, is one of the top prospects in baseball. He turned 21 years old on May 13.

Before Anthony’s debut,ย Milwaukee Brewers outfielder Jackson Chourio was considered the youngest player in MLB and even completed an impressive rookie campaign in the majors before being old enough to buy an adult beverage.

Chourio, who turned 21 on March 11, finished third in NL Rookie of the Year voting last year. He hit .275 with 21 home runs, 79 RBIs, and 22 stolen bases during his debut season.
