No. 9: Outfielder Miguel Bleis
Miguel Bleis is one of the more frustrating prospects I’ve ever watched. He so clearly has all the tools to be great. It’s a simple matter of his not putting them all together for extended periods of time. The 21-year-old will look like the best prospect you’ve ever watched in one series, then look lost the next. Injuries have also stopped him in his tracks multiple times.
Bleis slashed .222/.300/.385 with 21 doubles, one triple, and 14 home runs between High-A and Double-A. The right-handed hitter drove in 51 runs, scored 58 more, and stole 27 bases. His doubles total, home run total, RBI total, and run total were all career-highs. Bleis also struck out 23.9% of the time while only drawing a walk 9.3%. There’s also plenty of weak contact due to Bleis having poor swing decisions.
That being said, there’s legitimate power in his bat. If 2025 was the last time he hit under 15 home runs for the next 15 years, I wouldn’t be shocked.
Bleis has elite speed, an elite glove, and a fantastic arm. That combination should buy him some time as he tries to find some consistency with the bat. It also makes things a bit more frustrating, though, when you think about it. If Bleis could draw more walks and get his OBP higher, he’d steal 50-plus bases.
Bleis still has the potential to be a superstar outfielder. His bust potential grows a bit with each year, though. All the tools are 100% still there.

No. 8: Right-handed pitcher David Sandlin
David Sandlin had a strange 2025 season. Things start off rough, then he dominated for a stretch, then he lost it out of the bullpen. The Red Sox moving Sandlin to the bullpen to try to get him in position to help the major league roster in their postseason push should tell you how happy they were with what they saw, though.
The right-handed pitcher posted a 4.50 ERA, .254 BAA, and 1.37 WHIP in 32 appearances (14 starts) between Double-A and Triple-A. He struck out 107 batters compared to 40 walks in 106 innings.
Sandlin allowed one run on four hits over five innings in his lone Triple-A start. In his other 14 appearances at the level, he allowed 21 runs (19 earned) in 18 2/3 innings. That’s a 1.80 ERA in his Triple-A start and a 9.16 ERA as a reliever with Worcester.
It was an adjustment period, but Sandlin could be a dominant reliever. He should be back as a starter in 2026 (part of a potentially ridiculously loaded Worcester rotation).
The 24-year-old has a fastball that can reach 100 MPH with fantastic life to it. He loses command sometimes, but a big positive in 2025 was Sandlin’s ability to keep his velocity up (sitting in the mid-90s) later into games.
His slider works in the low-90s with a sharp (shorter) break to it. He leaves it flat on occasion, which leads to it getting hit around. However, when this pitch is working, it’s elite and will generate a lot of ugly whiffs.
Next is a splitter that sits around 90 MPH with a good drop to it. You’ll notice this a lot, it’s inconsistent. At times, Sandlin can get bad swings. Then there are times when he leaves it flat, and it gets hit around.
Finally, a mid-80s sweeper. Another pitch with a good break to it that can get Sandlin some strikes, but he doesn’t have 100% command of it at all times. It is his most “work-in-progress” pitch, so it’s the one I feel the most confident in saying could get better.
Still, Sandlin has two elite pitches. He just needs to work on getting more consistent with his repertoire (mainly his secondaries). When he’s in a hot stretch, he’s fun to watch, but the wheels have come off at times. He’ll make an impact in the majors soon.

No. 7: Catcher Johanfran Garcia
Johanfran Garcia could’ve let that devastating knee injury early in the 2024 season derail his career. There was immediate speculation that it would, at the very least, seriously jeopardize his ability to be a catcher.
Garcia rehabbed in the FCL from May 20 to June 7. He was promoted to High-A on June 10. In 46 games at the level, the right-handed hitter slashed .249/.327/.428 with four doubles and nine home runs. He drove in 28 runs, scored 27 more, and stole one base. Garcia caught 35 of the 46 games he appeared in (was the designated hitter for the other 11 games). The Red Sox made it pretty clear that they still view Garcia as a catcher long-term.
Jhostyxnon’s younger brother struck out a ton in High-A (30.6% K rate). However, he had never played at the level, barely played in Single-A, and was playing after a more than year-long hiatus.
Garcia’s good at taking what the pitcher gives him, but also has phenomenal power (which plays even better as a catcher). He also showed a propensity for clutch moments, with three walk-offs in 2025.
Garcia was already a below-average runner. After a serious knee injury, he looked even slower. Speed will never be a part of his game, and it doesn’t need to be.
Garica looked really good behind the plate, which was encouraging. He has a strong arm and could control the run game.
Garcia is still the best catching prospect in the system, even after a serious injury. At just 20, there’s plenty of time for him to grow and continue to polish his game. Don’t be shocked if he is hitting 25-plus home runs in the majors in a few seasons.

No. 6: Infielder Mikey Romero
Mikey Romero had his second straight big year in the minor leagues. The left-handed hitting infielder slashed .245/.300/.452 with 33 doubles, four triples, and 17 home runs. He drove in 76 runs, scored 61 more, and stole five bases.
Romero drew more walks in 2025, but he also struck out plenty. He made a point to work on that last offseason, and knowing his work ethic, he’s probably in the lab again.
What really stood out was his power. Romero has a gorgeous swing, and it’s starting to produce a lot of hard-hit balls. He was always someone who had the potential to rack up doubles. Now he’s looking like a serious 25-plus home run threat from the middle infield.
Speaking of the middle infield, he was fine defensively at second base, shortstop, and third base. His arm plays fine at third base and shortstop, and is above-average at second base.
While he’s not a speedster and won’t steal many bags, Romero is an athlete and has no problem taking extra bases. His range looked fine in 2025 as well.
The 21-year-old has been healthy for the most part over the last two seasons, and we’re seeing rapid growth out of him. He could end up having a long career as a power-hitting second baseman.
