Another big-time prospect was called up to the MLB on Monday.

They can't get any bigger than this one though, as No. 1 prospect Roman Anthony was called up by the Boston Red Sox.

Let's discuss Anthony's fantasy outlook as he gets set to make his MLB debut.

Anthony Grades and Minor League Stats

As already mentioned, Anthony is the top prospect in all of baseball.

He is just 21 years old, stands 6-foot-3 and weighs 200 pounds. Anthony is a left-handed hitter, but throws right-handed. He was drafted in 2022 by the Red Sox, going 79th overall.

He's graded as a 65 overall player. Anthony is the only player over a 60 overall.

Anthony has 60 marks for his hitting and power. He has 50 marks for his running, arm and fielding.

He's been great in his four minor league seasons so far. Anthony has a career .285 average and .402 on-base percentage across 303 games. Anthony also has 323 total hits, including 72 doubles, 10 triples and 42 home runs. He has tacked on 170 RBIs, 223 runs scored, 41 stolen bases, 225 walks and 310 strikeouts to his numbers over the years.

Anthony has played all 58 of his minor league games this season in Triple-A. He sports a .288 average and .423 OBP. He has 10 homers, nine doubles and two triples among his 61 total hits, along with 29 RBIs, three stolen bases, 45 runs scored, 51 walks and 56 strikeouts.

You can see by his numbers that he's a very well-rounded player. 

In the minor leagues, Anthony has played all three outfield positions and also been utilized as the designated hitter. He's played 170 games in center field, 52 in left field and 31 in right field.

Anthony's Fantasy Outlook

Anthony will join a Red Sox team that has plenty of talent on it, but which has underperformed so far in 2025.

Ceddanne Rafaela has been the team's center fielder most days. He's got solid numbers overall, and I don't think the team is giving up on him as he's just 24 years old.

Jarren Duran has played left field most often. He's taken a step back from his numbers in 2024, but there's no chance the Red Sox are moving on from him either.

Wilyer Abreu has been the team's right fielder most games this year. He has pretty solid numbers this season as well.

There doesn't seem to be a spot for Anthony everyday in the outfield, but Boston isn't going to call him up to have him ride the bench.

UPDATE: Abreu was placed on the 10-day injured list, so Anthony is likely to start in right field most days.

I'd say he could be the team's designated hitter, but we all know Rafael Devers isn't going to give that role up anytime soon. 

In his first big league game on Monday against the Rays, Anthony is going to start in right field and bat fifth. It remains to be seen how he will get in the lineup daily otherwise, but again, Boston is going to find a way to get the No. 1 prospect in there every game.

It might take a little time to figure out who exactly sees less playing time as a result of Anthony being called up. 

We'll keep an eye on both Anthony and other Red Sox hitters and let you know how to react in the days, weeks and months to come.

Should You Add Anthony to Your Fantasy Team?

At the time this article was published, Anthony was rostered in 49% of fantasy leagues. You can expect that number to rise before tonight's game gets going, and by tomorrow morning.

I fully expect Anthony to be one of the most-added waiver wire options, and I'll cover him in the morning as well.

Being the top-ranked prospect who was near a big league call up, that explains why Anthony was already rostered in so many leagues. It also means that he should instantly be added in all fantasy leagues.

Anthony should be rostered in all deeper redraft leagues by the end of the night, then be added in most standard redraft leagues by the end of tomorrow.

If you aren't comfortable adding and playing Anthony right away, just stash him on your bench. He could be a fantasy difference maker, and be one of the better fantasy hitters the rest of the season.

Those are high expectations for a guy getting his first taste of the big leagues, but that's what comes with being the No. 1 prospect.

I'd add Anthony if he was available in my league, then roster him for a week at minimum. You can assess how he's performed at that point and react accordingly. There's a good chance he sticks in the big leagues all season, and is a daily fantasy starter in short order.

You don't want to miss out on that, so add and stash Anthony on your fantasy team at the very least.
