Roman Anthony’s time has finally come.

The Red Sox are calling up the 21-year-old outfielder, who is widely considered to be the No. 1 prospect in baseball, The Post’s Jon Heyman confirmed.

He is expected to start Monday night against the Rays.

Anthony, a second-round pick in the 2022 draft, is hitting .288 with 10 home runs, 29 RBIs and a .913 OPS in 58 games this season for Triple-A Worcester.

He crushed a 497-foot grand slam on Saturday, which seemed to make his big-league readiness undeniable.

The Red Sox (32-35) have disappointed thus far, though they just took two of three games from the Yankees in The Bronx over the weekend.
