When a massive prospect is called up to the big leagues, the fantasy baseball world tends to lose its collective minds. We likely have another case because on Monday morning, Boston Red Sox prospect Roman Anthony got the call that he would be coming to the majors. In leagues that have not run their FAAB yet, or have prospects available after their arrival, Anthony will surely go for a massive haul.
Do these types of investments always work out, specifically in redraft leagues? Of course not. We should always learn the lesson from Jackson Holliday in 2024. Massive minor league success doesn’t always translate into big league production. Now that he is up, who deserves their time in the big leagues and who needs some more seasoning? This prospect report will provide a quick, weekly glance at MLB’s top hitter and pitcher prospects and how they are performing in the minors or their first few games with the big club.
As players graduate to the Major Leagues, new names will always take their place as the season goes along, but for now, some prospects are just starting to get their first shots. All stats are as of games completed on June 8th. Today’s piece will focus on the most relevant prospect news from around the minor leagues, focusing on the biggest names in the 2025 Top 100 list.
Fantasy Baseball Prospect Report
Jac Caglianone, KCR, 1B
Jac Caglianone’s first 25 plate appearances have not been very eventful to start his big league career. He is hitting .240/.240/.320 with no walks, no runs, and one RBI. While the results may not be there quite yet, Caglianone is hitting the ball very hard (57% hard-hit rate, 14% barrel rate) and has had some bad luck on what would have been several extra base hits.
Kyle Teel, CHW, C
Kyle Teel was another major hitting prospect who was called up this week, and flew somewhat under the radar after the news of Jac Caglianone and Roman Anthony. Teel has had more success than either of them, with a .375/.500/.375 line through his first three games. He also has an incredible 20% walk rate and speed that will eventually arrive. Teel had seven steals in 50 minor league games this season before being brought up to the White Sox.
Roman Anthony, BOS, RF
After much anticipation, Roman Anthony officially got the call-up to the majors on Monday while the Red Sox put Wilyer Abreu on the IL. His debut was an uneventful one, going 0-for-4 with a walk and an RBI. But his final AAA line this year landed at .288/.423/.491 with 10 home runs, three steals, and a 19% walk rate. The big games are certainly coming down the road, but some patience will be required as Anthony – baseball’s top hitting prospect – adjusts to Major League pitching.
Samuel Basallo, BAL, C
Samuel Basallo continues to absolutely rake for Baltimore’s AAA affiliate and is pushing the question of whether or not Baltimore will take a chance on calling up a 20-year-old if the team makes a playoff push. Basallo now has 13 home runs and 26 RBI, plus a .252/.365/.595 line. Like Jac Caglianone, he also has a 57% hard-hit rate and a 94 miles per hour exit velocity. Will he see the majors this year? If the injuries for Baltimore continue to mount up, it may force their hand.
Ronny Mauricio, NYM, 2B
Of all the recent hitting prospects to get a call-up, Ronny Mauricio might be off to the best start of any of them. Through five games, Mauricio is hitting .263/.333/.474 with a home run, two steals, and four runs. This is all after hitting .323/.384/.508 in the minor leagues to start the year after missing all of 2024 with a knee injury. With Mark Vientos on the IL and Brett Baty and Jeff McNeil doing nothing to impress the Mets this season, Maurico has a chance to stick with the team all season
Mick Abel, PHI, SP
After defeating Paul Skenes in his first start of his MLB career in May, Mick Abel was brought back to the Phillies with the Aaron Nola injury, and faced his second test against Toronto. After six innings, no runs, and nine strikeouts in his debut, Abel pitched another 5.1 innings and allowed just one earned run. Overall, that’s now a 0.79 ERA and a 0.706 WHIP through 11.1 innings.
Marcelo Mayer, BOS, 3B/SS
Roman Anthony isn’t the only rookie who’s been recently called up for the Boston Red Sox. Recently, they called up infielder Marcelo Mayer, and he has played 12 games so far, totaling 39 plate appearances. He hit one monster home run against the New York Yankees this weekend, but has otherwise struggled with a .222 average and a 26% strikeout rate. However, with the injuries to Alex Bregman and Triston Casas, Mayer is likely to get a very long look in Boston as he fills in all over the diamond.
Michael McGreevy, STL, SP
Twenty-four-year-old Michael McGreevy was called up for his first start of the season this weekend, but he just happened to run into the Los Angeles Dodgers. Fortunately, McGreevy was able to come away not terribly damaged, allowing four earned runs in six innings while striking out five. Put together with his early May outing against the Mets. McGreevy now has a 3.09 ERA with 10 strikeouts and a 0.857 WHIP.
Nick Kurtz, ATH, 1B
Nick Kurtz was officially activated off the IL on Monday afternoon after 10 days away. He immediately found a spot as the DH in the lineup Monday night, but went 0-for-4 in his first game back from a strained hip flexor. The timing was incredibly disappointing because Kurtz was just finding his groove before he got hurt, and had hit five home runs with 15 RBI just shortly before he was hurt and forced to the IL. He should continue to have strong power upside this year as he gets back into the MLB groove again.
Trey Yesavage, TOR, SP
Starting pitcher Trey Yesavage makes the list for the first time this year. Twenty-one-year-old Yesavage was the 20th overall pick last year and was recently promoted to AA after dominating the rookie leagues and other minor league affiliates. In his starts prior to AA, Yesavage put up a 2.13 ERA, 0.85 WHIP, and 88 strikeouts in 50 innings this season. If Yesavage continues to pitch like this in AA, the Blue Jays will have no choice but to call him up at some point for a cup of coffee in 2025.
