Red Sox prospect Roman Anthony made his MLB debut at Fenway Park while his sister Lia went viral, gaining thousands of Instagram followers and receiving numerous DMs.

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.

Roman Anthony's sister has spoken out after going viral during his debut and gaining thousands of followers overnight.

The Boston Red Sox called up Roman Anthony, baseball's consensus No. 1 prospect, Monday before beginning a six-game homestand.

Left-handed hitting rookie Roman Anthony will start in right field vs. Yankees left-handed starting pitcher Ryan Yarbrough. The Red Sox and Yankees will play the first game of a three-game series at 7:10 p.m. here at Fenway Park. With Duran sitting, Rob Refsnyder will play left field and lead off.

Roman Anthony gets a positive sign he'll remain in the Major Leagues once Wilyer Abreu is called up, based on the Boston Red Sox moving his locker to a more permanent spot.

Alex Bregman praises top prospect and Red Sox rookie Roman Anthony for reaching a milestone he never has, even with years in the big leagues.

Those behind the camera zoomed in on the stunning brunette, who wore a red tube top and matching lipstick, multiple times.

The Red Sox hope to spark their offense with a player who hit a 497-foot home run on Saturday for Triple-A Worcester.

Anthony received the biggest cheer of all during pregame introductions and then a standing ovation when he came to bat in the second inning.

For some, it might seem that Kristian Campbell, Marcelo Mayer and Roman Anthony have cleared the highest hurdle in their baseball journeys — making the leap between Worcester and the parent club in Boston.
