Big news came last week for a number of the best Major League Baseball prospects. Due to a series of combinations of injuries, poor performances by big league players, or other opportunities, many minor league prospects got their first real shot at the big leagues. Other prospects have been dominating the level they were at, so several names inched even closer to their Major League clubs. This is the time of year when prospect news comes fast, and we will do our best to keep you up to date so your fantasy rosters can react.
With about four months left in the 2025 season, we are bound to see many more players graduate from the minor league level to their shot at the majors. 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 prospects and how they are performing in the minors.
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 May 25. Today’s piece will focus on the most relevant prospect news from around the minor leagues, focusing on the biggest names in the Top 100 list.
Fantasy Baseball Prospect Report
Alejandro Osuna, TEX, OF
After hitting .279/.386/.416 with nine steals in 39 minor league games this season, the Texas Rangers called up prospect Alejandro Osuna after the news that Joc Pederson broke his hand. Osuna went hitless in his debut on Sunday, but had two hits in three at-bats against Toronto on Monday. Osuna has very little power (no minor league stop with 10 home runs), but his on-base ability and speed should keep him in the lineup most days while the Rangers deal with injuries and poor hitting up and down their lineup.
Roman Anthony, BOS, RF
Roman Anthony is proving he really deserves a call-up to the Major League club at some point this summer. And with every passing day, he is making the case that it should be soon. With AAA Worcester, he is now hitting .321/.453/.518 with seven home runs and three stolen bases. Right now, there is no talk of bringing Roman Anthony up to Boston after the Marcelo Mayer promotion. The Red Sox have also been adamant that they do not want Anthony to learn first base and practice there in AAA, even in the wake of the season-ending injury suffered by Triston Casas.
Samuel Basallo, BAL, C
Samuel Basallo has started crushing the ball in AAA Norfolk over the last two weeks. In that span, he has four home runs and a .282/.391/.667 slash line. Overall, he now has seven home runs on the season and would appear to be a nice bat the Orioles could add to help jumpstart their struggling offense. However, the problem is that all of Basallo’s positions (catcher and outfield) are taken by incumbents. Some thought the Tyler O’Neill injury would force Baltimore to call up Basallo, but they instead went with Dylan Carlson, who is hitless in 17 plate appearances with a 47% strikeout rate.
Dalton Rushing, LAD, C
Since his promotion to the Dodgers, Dalton Rushing has played in five games and seen extremely mixed results. He has a .250 average, but only a .313 slugging percentage as he has yet to record a home run or a steal. But most disturbingly, Rushing has a 47% strikeout rate in his first stint in the Major Leagues. This is a far cry from his .308/.424/.514 line from AAA this season, but he will continue to need an adjustment period. Rushing is playing in the big leagues for the first time and is also adapting to playing on a backup catcher schedule, where he likely has been a starting player at every stop since high school. His bat should turn it around very soon.
Logan Henderson, MIL, SP
Starting pitcher Logan Henderson has gotten off to one of the best rookie starts of the season, perhaps of the last several seasons. In his first four big league starts, Henderson went 3-0 with a 1.71 ERA and 0.95 WHIP. However, with injuries on the roster and different needs pressing Milwaukee right now, the Brewers demoted Henderson back to AAA Nashville on Monday. Henderson is still young at just 23 years of age, but his performance over the last two weeks proves he is likely to be back again soon, considering the state of Milwaukee’s pitching rotation.
Marcelo Mayer, BOS, SS
With Alex Bregman suffering a serious quadriceps injury, the Red Sox turned to one of their best prospects, Marcelo Mayer, to help with their issues at third base and first base. Mayer projects to play all over the infield and should see playing time almost every day, although the majority will be at third base. After not getting a hit in his first game, Mayer with 2-for-4 with a run scored on Sunday against Baltimore. Mayer was hitting .271/.347/.471 in AAA with nine home runs and two steals, so he has some pop in his bat and speed at his disposal. Perhaps most encouraging, Mayer hit sixth in both of his first two games, and the Red Sox don’t seem interested in burying him in the lineup.
Jac Caglianone, KCR, 1B
If the Kansas City Royals thought first base prospect Jac Caglianone would go to AAA from AA for a long period of time and learn the adjustments, then Caglianone has set out to prove them wrong. Since being promoted to AAA Omaha, Caglianone is hitting .346 with five home runs and 10 RBI. He is destroying that level just like he did at the AA level earlier this year. The Royals’ offense ranks 27th in both runs and wRC+ and is in the bottom five in slugging percentage this year. Caglianone would be an instant boost to this offense, and the path might have been made clearer by the release of corner outfielder Hunter Renfroe. If the Royals can find a place for Caglianone at either DH or first base, I imagine he would have a long leash.
Noah Cameron, KCF, SP
Another Royals prospect! When the Kansas City Royals called up pitching prospect Noah Cameron ahead of a start he would make on April 30, in their wildest dreams, they did not expect what Cameron has produced so far this season. In three starts, Cameron has pitched 19.1 innings, allowed a 0.93 ERA, and a 0.67 WHIP. Somehow, he has just a 1-1 record, but his stuff has been electric since he came up to the big club. With Seth Lugo, Cole Ragans, and Kyle Wright all out with injuries, Cameron is likely to stick around for a bit, where he can continue his amazing start.
Travis Bazzana, CLE, 2B
Just when 2024 top pick Travis Bazzana was starting to play well, he suffered an injury to his right side, which might cause him to miss some time. Overall, he has four home runs and eight steals on the season in AA, but he was hitting .333/.471/.556 over the last two weeks and was really pushing for a promotion to AAA before the injury. The latest prognosis from the Guardians is that Bazzana will miss 8-10 weeks with an oblique injury. The number one pick may now see his debut for 2025 in MLB in jeopardy. If he is out through July and needs time to rehab before going back to AA, it may be too much to push him to the majors before the end of the season.
