BOSTON — Roman Anthony, Baseball America’s No. 1 prospect, has been in the major leagues for less than a week but Red Sox star Alex Bregman has seen enough. “I think he’s gonna be one of the best hitters in all of baseball,” Bregman said before Boston’s 2-1 walkoff win in 10 innings over the Yankees on Saturday.

The Boston Red Sox promoted outfielder Roman Anthony to the majors, the team announced Monday. Anthony was in the starting lineup against the Tampa Bay Rays, batting fifth and manning right field. Wilyer Abreu landed on the injured list with an oblique strain.

Boston Red Sox manager Alex Cora has been sitting Mayer and Anthony against left-handed pitchers, but some are arguing that needs to change.
