The newest addition to the Team USA World Baseball Classic roster is also its youngest.
Red Sox outfielder Roman Anthony was officially named to the roster on Tuesday, Feb. 16. He replaces the Diamondbacks’ Corbin Carroll, Team USA announced after it had been reported last week. Anthony, who debuted with 71 games in 2025 and finished third in Rookie of the Year voting, batted .292 in Boston with eight home runs and an OPS+ of 140.
While Anthony may be a bit of a downgrade in terms of outfield coverage from Carroll, he will bring a stronger arm and he can make up for the difference in bat pop. Anthony joins teammate Garrett Whitlock, one of the best aces in baseball, on the WBC roster.
Anthony signed an eight-year contract worth $130 million with the Red Sox last August, and the deal has escalators up to $230 million. Though he missed out on $1 million for not finishing top two in Rookie of the Year voting, he can make $2 million for winning MVP, $1 million for finishing second or third in MVP voting, with descending numbers down to top-10 in voting.
The USA outfield will now have Anthony, Byron Buxton, Pete Crow-Armstrong, and captain Aaron Judge.
How old is Roman Anthony?
Born May 13, 2004, Anthony is 21 years old and will be 22 in May. He is the youngest player on the Team USA roster.
Anthony became the youngest Red Sox player to make his debut since Rafael Devers at 21 years and 27 days on June 9 against the Tampa Bay Rays.
