- 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. Nuxhallโs 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.
