Prospects1500 Tiers:
Tier 1: Players with high expectations of both making the majors and playing at an All-Star level for a number of years
Tier 2: Players with an above-average expectation of making the majors and being a solid contributor
Tier 3: Players with an average expectation of making the majors and being a solid contributor
Tier 4: Players who have the potential to make the majors; possible sleeper candidates for sustained MLB success
Tier 5: Players of interest, worth keeping an eye on, who may make (or have made) the majors but provide minimal impact
Levels listed for each player are the highest levels player reached in 2024
Tier 1
1. Roman Anthony, OF, 20, Triple-A
Anthony rounded out 2024 slashing .335/.463/.519 in Triple-A, solidifying his status as one of, if not the best, prospects in baseball. Despite being in an organization with Rafael Devers and Triston Casas, it may have come as a surprise to learn that Anthony had the hardest-hit ball in the entire system. His elite bat speed and immense power were on full display throughout the 2024 season, and his OPS consistently improved month by month. With his impressive profile, he projects to be a major impact player for the Red Sox in the near future. After being named the MLB Pipeline No. 1 hitting prospect, that impact could come as early as Opening Day. (@aj_greene1015)
2. Kristian Campbell, 2B/OF, 22, Triple-A
To call Campbell’s 2024 ascent as meteoric would almost be an understatement. He began making a name for himself during Spring Training where he was posting head-turning exit velocities, which maxed at 111.2 mph during the year. He went on to have an incredible season, being promoted to both Double-A and Triple-A, leading MiLB in wRC+ (180) and finishing second in OPS (.997). Campbell slotted in at No. 45 on the Red Sox top 50 last January; jumping 43 spots (and into the top five on Baseball America’s overall prospect rankings) and winning MiLB Hitter of the Year capped off a year where he took the prospect world by storm.

3. Marcelo Mayer, SS, 22, Double-A
In an unprecedented move in mid-August, the Red Sox promoted all three of their top prospects, Mayer, Anthony, and Kyle Teel, to Triple-A Worcester together. Unfortunately, Mayer’s season was cut short due to a lumbar injury before he could make his debut. Despite this setback, Mayer has a strong arm at shortstop along with one of the smoothest swings in the system and he has the potential to become a All-Star caliber Major League player. For the first half of the 2024 season, Mayer was one of the top hitters in Double-A, showcasing his ability to hit for both average and power. 2025 is tracking to be the year Mayer finally breaks through and starts games at Fenway.

Tier 2
4. Franklin Arias, SS, 19, Single-A
The 2024 Florida Complex League Top Prospect and MVP, Arias has shot up the system ranks into Boston’s top 5. Similar to the meteoric ascension of Campbell last year, the 19-year-old was 42nd on our Sox Top 50 last year at this time, but came in 9th on our midseason list in August. He’s now cemented himself as an overall top 100 prospect (No. 76 on both MLB Pipeline and Baseball America), and could find himself splitting time between High/Double-A this year. We can never put too much stock into Rookie ball numbers, but across both FCL and Single-A as an 18-year-old, Arias slashed .309/.409/.487/.896, with 25 doubles, 2 triples, 9 HR and 35 SB. (@Scotty_Ballgame)
5. Luis Perales, RHP, 21, Double-A
Expectations were high for Perales entering 2024. He had debuted as a top 100 prospect last offseason, and was coming off a strong 2023 so it was encouraging to see him earn a quick promotion to Portland after seven successful starts in Greenville. He went down with a UCL injury which cost him the year, and may cost him all of 2025. While developing his sweeper, he had improved his BB% from 12.7% in 2023 to 8.3% in his initial nine starts. It’s worth noting his durability concerns, but as a power-throwing 21-year-old, Perales continues to progress as the current top arm in the system despite the injury. (@aj_greene1015)
Tier 3
6. Miguel Bleis, OF, 20, High-A
There’s plenty to dream on with Bleis, particularly his speed and raw power, but unfortunately things haven’t fully clicked since he was signed in 2021. Bleis was promoted to High-A last June and struggled mightily with a slash line of .190/.265/.319/.584 over 52 games. However, it was only his age 20 season and he was coming off a significant injury from the prior year. If you include his time at Single-A to begin 2024, he swiped 38 bags, clubbed 11 homers, and had a tolerable strikeout rate of 21.4%. Bleis still has time to develop into his 5-tool potential, but 2025 will be a pivotal season for the BoSox and dynasty owners. (@BBoxscore)
7. Yoeilin Cespedes, SS, 19, Rookie (FCL)
A fracture to the hamate bone in his left hand cut his 2024 season short which is a shame because he was tearing the Complex League up. At the time of his injury, he had a 1.015 OPS and .297 ISO good for a 163 wRC+. He is not a big guy but his short compact swing packs more punch than one would expect. If not for the injury he would likely have seen some at bats in Single-A but that will have to wait for 2025. (@JMahyfam)
8. Jhostynxon Garcia, OF, 22, Double-A
Jhostynxon, pronounced Yos-Tin-Son (yes, I had to look that up), had a breakout 2024 season. Across three levels (Single through Double-A), he slashed .286/.356/.536 with 23 home runs and 17 stolen bases good for a 151 wRC+. Some scouts are down on his hit tool, but he has cut his strikeout rate every year. He is not very patient at the plate but if he can keep the K rate around 21%, I think it could work. I really like the prospect and think he should be the radar of dynasty owners. (@JMahyfam)
9. David Sandlin, RHP, 23, Double-A
Boston’s return in the John Schreiber trade to Kansas City last February, Sandlin brings some dominant stuff to the Sox pitching pipeline. Hitting triple digits in some offseason bullpens, look for the 6’4” righty to open 2025 in the Portland Sea Dogs’ rotation, although he could potentially move to the bullpen, depending on where the organization sees him flourishing. Sandlin participated in the Red Sox Rookie Development Program last month, and there’s a good amount of upside here. Don’t be too concerned about his 2024 5.34 ERA across High/Double-A, but definitely keep an eye on his WHIP (1.38), which needs to come down if he wants to move to Triple-A and eventually Boston. (@Scotty_Ballgame)
10. Richard Fitts, RHP, 25, MLB
The 6’3” 230lb Fitts had a successful MLB debut in September, starting four games for the Red Sox, tossing 20.1 innings and giving up only four earned runs (1.74 ERA), and all of them came in his final start. He wasn’t close to his career Minor League 9.6 K/9 in those first MLB appearances (only 9 Ks, 3.9 K/9), but he was effective and kept the team in three of those four outings. Roster Resource projects him to be atop the WooSox rotation to start 2025, and depending on how the Major League squad’s starters perform over the first month or two of the season, Fitts could be back in Boston sooner than later. (@Scotty_Ballgame)
11. Hunter Dobbins, RHP, 25, Triple-A
In November, the Red Sox added Dobbins to the 40-man roster along with Jhostynxon Garcia to protect him from the Rule 5 Draft. After a 120 strikeout season with a 3.08 ERA (3.04 FIP), it seemed like an easy decision. Dobbins has one of the most extensive arsenals in Boston’s system, including a new sweeper and a modified splitter now known as the infamous “splinker.” Impressively, Dobbins allowed only two home runs in all of 2024, demonstrating his ability to keep the ball in the park over his 125.2 innings pitched.

12. Mikey Romero, SS, 21, Double-A
13. Jedixson Paez, RHP, 21, High-A
14. Payton Tolle, LHP, 22, College
15. Allan Castro, OF, 21, Double-A
16. Connelly Early, LHP, 22, Double-A
17. Yordanny Monegro, RHP, 22, High-A
18. Conrad Cason, RHP/SS, 18, High school
19. Blaze Jordan, 3B/1B, 22, Double-A
20. Isaac Coffey, RHP, 24, Double-A
21. Zach Penrod, LHP, 27, MLB
22. Juan Valera, RHP, 18, Single-A
23. Luis Guerrero, RHP, 24, MLB
After a lackluster 2023, Romero bounced back in 2024. He hit six home runs in his first 11 games in Double-A. Tolle was their 2024 2nd round pick, and is 6’6’’ 250 lb lefty starter. He won Big 12 Pitcher of the Year with TCU. Monegro went on a dominant stretch to close out the year in Greenville where he didn’t give up an earned run in 39 IP between July 14 and September 1. Cason, Georgia’s 2024 Gatorade High School Player of the Year as a two-way player, posted a 0.48 ERA and a 1.064 OPS. His pro debut will be one of the major focus points for the Red Sox farm in 2025. Penrod pitched his way into a relief role with the MLB squad after his velocity took a huge leap after moving to the bullpen. Among qualified Red Sox MiLB pitchers in 2024, Valera allowed the lowest AVG (.125), OPS (.411) and WHIP (0.85). Guerrero can hit triple digits on the radar gun, and in a late season promotion to Boston, didn’t give up an earned run in ten innings out of their bullpen. (@aj_greene1015)

48. Max Carlson, RHP, 23, High-A
49. Tyler Uberstine, RHP, 25, High-A
50. Anderson Fermin, OF, 18, Rookie (DSL)
Johanfran Garcia was hitting equally as well as his brother, Jhostynxon, to begin the season but missed most of 2024 after he tore his ACL. After trading Kyle Teel, catching depth is of even greater importance so his defense will be greatly anticipated once healthy. Brannon went to the Arizona Fall League and hit well, slashing .309/.347/.803 and was named an AFL All-Star. Gonzales signed out of the Dominican for $250K last January, and had an excellent debut in the DSL and displayed plus power. He’ll be stateside for the 2025 season. In his first year in the system, Wehunt made 22 starts between Single-A to Double-A and struck out 110 while developing a new cutter. Narváez was acquired via trade from the Yankees, and could earn the second catching spot on the 26-man roster out of camp. Fajardo was also acquired via trade, and was a DSL All-Star with the White Sox in 2024. Uberstine returned in August with a 1.93 ERA in three appearances as an opener after having Tommy John in June 2023. (@aj_greene1015)
