Miami’s system looks completely different now than it did at this point last year. Following a disappointing start to the season, the Marlins once again tore things down to the studs and have continued to do so this off-season. Five of the top seven prospects on this list have been acquired from different teams. The influx of talent into the system adds depth behind their two top pitching prospects, Noble Meyer and Thomas White. The Marlins now have several hitting prospects knocking on the door of the major leagues.
This article is part of a series focusing on each MLB team’s top 20 prospects for fantasy baseball heading into the 2025 season. Stay tuned for prospect breakdowns for all 30 teams throughout January here at Pitcher List, and be sure to check out all our published pieces in the series.
Top Marlins Prospects
The Top Tier
1) Thomas White – SP, 20 YO
2024 Stats (A/A+): 96.0 IP | 2.81 ERA | 29.2 K% | 9.2 BB%
The Marlins have seen several pitching prospects come up and make an impact at the major league level. They started to replenish their backlog of pitchers in the 2023 draft, spending their first-round pick on Noble Meyer, but the real prize from the draft seems to be Thomas White who they grabbed 35th overall. Coming out of a Massachusetts high school, the harsh winters of the Northeast limited the amount of scouting that teams could perform on him. White made his debut in 2023, throwing 4.1 innings and ultimately pitching in last year’s Spring Breakout game. His comfort on a professional mound grew as the season moved along. White showed off big strikeout potential while improving his control as the season moved along.
White’s arsenal is comprised of three pitches. His fastball is a plus offering and is the one he is most comfortable throwing at this point in his career. The pitch sits in the mid-90s and generates over 16 inches of vertical break. His go-to strikeout pitch is a slurve that generates whiffs at a high rate. Against lefties, White really only throws his fastball and slurve. When facing righties, White mixes in a changeup as well, which is a distant third pitch. The development of this pitch and his ability to mix up his arsenal against lefties could be the key to White reaching his potential. White’s performance on the mound in his first professional season should make dynasty managers excited about what is to come.
2) Noble Meyer – SP, 19 YO
2024 Stats (A/A+): 74.0 IP | 4.01 ERA | 26.6 K% | 17.2 BB%
While White has generated the most buzz from a dynasty perspective, their first-round pick from last year is no slouch either. Noble Meyer was considered one of the top prep arms in last year’s draft and was grabbed by the Marlins 10th overall. The 6’5″ righty has an athletic build and the hope is he can continue adding velocity as he develops. Right now, he relies heavily on a sinker, sitting 92-95 mph on the gun. The pitch gets over 14″ of arm side run helping to generate more whiffs than a traditional sinker. Going with his sinker is a plus-plus slider. The slider is Meyer’s go-to strikeout pitch. Meyer also has an excellent changeup that generates whiffs against lefties.
With two plus secondary offerings and a strong fastball, there is a lot to like in Meyer’s profile. The plus strikeout potential is important for dynasty managers long-term. The issue early on in his career has been control. In Meyer’s first season, he walked over 17% of the batters he faced. Meyer did not show any improvements in this area as the season moved along. There is a lot of development left, but Meyer will be 20 for the entire 2025 season. He has the potential to develop into a significant fantasy asset in an organization with a strong pitching development track record.
3) Robby Snelling – SP, 21 YO
2024 Stats (AA/AAA): 115.1 IP | 5.15 ERA | 22.6 K% | 8.9 BB%
After being drafted 39th overall in 2022 by the Padres, Robby Snelling’s success was instantaneous. Snelling made the move to professional baseball look easy. Snelling dominated three different levels in his first season, shooting his name up dynasty boards. Snelling’s fastball/slider combination makes his profile so enticing. What he lacks in velocity on the four-seam, he more than makes up for in movement. Snelling’s fastball gets over 17″ of vertical break on it to go with the seven inches of arm side run. The pitch plays well at the top of the zone and Snelling commands it well. His slider pairs nicely with it as well, diving away from left-handed batters. This is Snelling’s go-to pitch when he needs a strikeout and it profiles to be a plus offering.
While the hype around Snelling was significant, the concern in his profile entering 2024 was the lack of a true third pitch. With the Padres, Snelling’s 2024 season got off to a rocky start, but he settled in nicely following the midseason trade to Miami. More importantly, Snelling’s changeup looked much improved. If this pitch can even just turn into an average offering, Snelling’s profile improves drastically. He just turned 21 in December and is already knocking on the door of the major leagues. Snelling ranks behind Meyer and White but is still a very fantasy-relevant prospect to keep an eye on.
4) Agustín Ramírez – C/1B, 23 YO
2024 Stats (AA/AAA): .267 AVG | .358 OBP | .487 SLG | 25 HR | 22 SB | 18.6 K% | 11.1 BB%
The transformation of Miami’s farm system continued with a midseason trade with the Yankees. Ramirez headlined the return for Jazz Chisholm Jr. and is likely to make an impact as early as 2025. Ramirez originally signed with the Yankees out of the Dominican Republic back in 2018. His ascent through the minor leagues started slow, but he has put things together over the past year. The big-bodied backstop has a powerful swing. His arms explode through the zone with a big one-handed finish that makes his home runs feel even more emphatic. Ramirez finished 2024 with 25 home runs despite a relatively low launch angle. When Ramirez gets the ball in the air, there is a good chance it is going to go for a home run. He has excellent pull-side pop and is a threat for 30+ homers at the major league level.
Despite stealing 22 bases last season, Ramirez does not project as much of a speed threat at the major league level. Scouts have given Ramirez 30-grade speed but expecting more than 5-10 would be a mistake. The biggest question many have is how his defense will play. He is below-average behind the plate and a move to first base is not out of the question. For fantasy, this puts more pressure on Ramirez’s bat to play up.
5) Jakob Marsee – OF, 23 YO
2024 Stats (AA/AAA): .200 AVG | .345 OBP | .315 SLG | 10 HR | 51 SB | 22.4 K% | 15.3 BB%
There was a lot of excitement around the dynasty industry (including myself) for Jakob Marsee in 2024. Coming off a 2023 season in which he hit 16 home runs and stole 46 bases, Marsee looked equally as dominant in the Arizona Fall League. Speed, plate discipline, and contact skills seemed to all be part of the package for Marsee. Marsee struggled out of the gates at Double-A before being traded to Miami in the Luis Arraez trade. Marsee’s season did not get much better with Miami as he slashed just .205/.347/.315 between Double-A and Triple-A. His dynasty value has certainly taken a hit, but what went wrong?
Digging into his profile, there is reason for optimism. Marsee still has excellent plate discipline, giving his dynasty value a boost in OBP leagues. His speed also looked as good as ever. Despite his deflated numbers, Marsee stole 51 bases last year. He projects as a 40+ base stealer at the major league level. Marsee’s contact skills and batted-ball distribution also continued to look excellent. He continued to hit a lot of line drives and spray the ball all over the field. He should see better luck in the BABIP department moving forward. The issue in Marsee’s profile is a lack of power. His 16-home run outburst in 2023 seems like an outlier and he fails to offer much in terms of physical projection. Miami is not a great home ballpark for him and dynasty managers should not expect more than eight to 10 home runs a season.
6) Starlyn Caba – SS, 19 YO
2024 Stats (CPX/A): .228 AVG | .385 OBP | .284 SLG | 2 HR | 50 SB | 14.4 K% | 19.7 BB%
Starlyn Caba was the Phillies’ prized IFA signing from the 2023 period and was recently acquired by the Marlins in the Jesús Luzardo trade. Coming out of the Dominican Republic, Caba’s transition to professional baseball has looked, at times, too easy. Although dynasty managers do not pay much attention to defense, that is what scouts are enamored by with Caba. His fluency at shortstop is impressive and could allow him to move quickly through the minor leagues. For fantasy purposes, Caba’s hit tool is really impressive. Despite being just 18 years old in full-season ball, Caba posted a swinging strike rate below five percent. His contact skills are incredible and his patience at the plate is years beyond his age. Caba’s batting average dipped he was promoted to Low-A, but a .207 BABIP can explain most of those struggles.
Once on base, Caba has great speed. He stole 50 bases last season and his 600 PA pace was 88. Is Caba going to lead the league in stolen bases? Probably not, as his speed will likely slow down a bit as he matures. However, there is 40+ stolen base potential here. Caba’s hit tool and speed figure to carry his future dynasty value. At 5’9″, Caba lacks the physical size and projection to hit many home runs. His ceiling home run projection is likely in the 10-15 range. Nico Hoerner is a great future comp based on skillset. Still only 19, there is plenty of development left keeping Caba down at sixth on this list.
7) Deyvison De Los Santos – 1B/3B, 21 YO
2024 Stats (AA/AAA): .294 AVG | .343 OBP | .571 SLG | 40 HR | 1 SB | 24.7 K% | 5.8 BB%
The rebuild of Miami’s farm system continued with the addition of Deyvison De Los Santos. De Los Santos had a hectic 2024, to say the least. He was taken by Cleveland in the Rule-5 draft, returned to Arizona, hit 28 home runs, was traded to Miami, and then hit another 12 home runs. De Los Santos has effortless power that will play in any major league park. 40 home runs is incredible and it could be even higher if he would hit the ball in the air more. High ground ball rates have “limited” him from reaching his power potential. As crazy as it sounds, there is 50-home run power in his bat.
Why does a 50+ home run bat only rank seventh? Well, there are a lot of red flags in De Los Santos’ profile. In addition to the ground ball rate issue, De Los Santos has major hit tool concerns. He has an extremely aggressive approach at the plate trying to punish any mistake a pitcher makes. He chases a lot and whiffs a lot. De Los Santos whiffed over 35% of the time in Triple-A last season and that rate does not usually improve against major league competition. There is also the high likelihood that he will find his future home at first base or DH and not at third base. This makes it imperative that his bat play up to its potential. De Los Santos is going to hit home runs, but dynasty managers should expect batting averages in the low .200s.
Prospects Dynasty Managers Should Know
8) Carter Johnson – SS, 18 YO
2024 Stats (A): .221 AVG | .373 OBP | .292 SLG | 1 HR | 2 SB | 33.1 K% | 5.8 BB%
Carter Johnson has one of the prettiest left-handed swings to come out of the 2024 draft. The 6’2″ lefty from Alabama landed in Miami with the 56th pick in last year’s draft class. Johnson utilizes a small leg kick with an uppercut swing designed to pull the baseball. When he connects, it is easy to see the raw power in his bat. Johnson’s approach at the plate needs refinement and could lead to high strikeout rates. At just 18, there is a lot to like with Johnson’s pure athleticism.
9) Echedry Vargas – 2B/SS, 19 YO
2024 Stats (A): .276 AVG | .321 OBP | .454 SLG | 14 HR | 29 SB | 21.1 K% | 5.0 BB%
The Marlins traded away Jake Burger to the Rangers in one of the more surprising moves from this year’s winter meetings. The main piece coming back to Miami in that deal was Echedry Vargas. The 19-year-old middle infielder from the Dominican Republic put up solid numbers in Low-A this season. Vargas has a quick bat that leads to high pull rates and allows him to tap into significant raw power. He also has plus speed giving him a high fantasy ceiling. The issue is his hit tool. Vargas ran a swinging strike rate of 17% last year and is extremely aggressive at the plate. This could get him into trouble against tougher competition.
10) PJ Morlando – OF, 19 YO
2024 Stats (A): .000 AVG | .000 OBP | .000 SLG | 0 HR | 0 SB | 0.0 K% | 0.0 BB%
The Marlins first-round pick from this past year appeared in just one game before suffering a season-ending back injury. The projectable 6’3″ outfielder was a surprise selection at 16th overall with many doubting if he can hit enough and whether or not he can stick in the outfield. If he does, his left-handed swing is pretty and packs plenty of power. Morlando is a development project for Miami with big-time upside.
11) Nathan Martorella – 1B, 23 YO
2024 Stats (AA): .229 AVG | .306 OBP | .385 SLG | 18 HR | 8 SB | 18.2 K% | 9.3 BB%
Nathan Martorella’s numbers took a nose-dive after being acquired by the Marlins this past year. The main reason for the dip in numbers was a .226 batting average despite a line drive rate that remained over 20%. Martorella has an average hit tool, slightly above-average power, and good plate discipline. He profiles as a high-floor low-ceiling option at first base.
12) Abrahan Ramirez – 2B, 20 YO
2024 Stats (CPX): .348 AVG | .447 OBP | .513 SLG | 2 HR | 6 SB | 15.9 K% | 15.3 BB%
Coming over to Miami at this year’s trade deadline from the Yankees was Abrahan Ramirez. Ramirez was signed by New York out of Venezuela and has put up intriguing numbers in his brief professional career. Despite his age, Ramirez has a mature understanding of the strike zone which helps him to work walks, get on base, and utilize his speed which is his best tool. There is still a long way to go for Ramirez who has yet to play a game above the Complex League, but a 161 wRC+ there makes him a prospect to keep your eye on.
13) Andres Valor – OF, 19 YO
2024 Stats (CPX): .289 AVG | .374 OBP | .421 SLG | 2 HR | 35 SB | 25.1 K% | 8.8 BB%
If you are looking for athletic upside, add Andres Valor to your list. Valor was signed out of Venezuela back in 2023 and stands at 6’3″. The super athletic outfielder put together a strong showing in the DSL in 2023 and carried that over to the Complex League in 2024. Right now, Valor’s best tool is his speed. He stole 35 bases in just 227 plate appearances but has the bat speed, pull-side awareness, and physicality to turn into a significant dynasty prospect.
14) Adam Mazur – SP, 23 YO
2024 MiLB Stats (AA/AAA): 93.1 IP | 4.73 ERA | 24.0 K% | 4.7 BB%
2024 MLB Stats: 33.2 IP | 7.49 ERA | 13.9 K% | 13.3 BB%
Prior to being traded to Miami, Adam Mazur had fallen flat on his face in his major league debut. Excellent control and a deep arsenal carried Mazur through the minor leagues but that all disappeared in the major leagues. Every pitch in Mazur’s arsenal graded out as below-average in terms of stuff, limiting his future dynasty potential. Still, Mazur projects as a back-end starter who could be worthy of a stream in the right matchup for fantasy managers.
15) Joe Mack – C, 22 YO
2024 Stats (A+/AA): .252 AVG | .338 OBP | .468 SLG | 24 HR | 3 SB | 24.9 K% | 10.7 BB%
Since being drafted 31st overall, Joe Mack had largely failed to live up to the lofty expectations. However, catching prospects notoriously take longer to develop offensively due to the rigors of their defensive responsibilities. Mack finally seemed to put it all together in 2024. He hit a career-high 22 home runs and projects to have above-average power. He is unlikely to ever hit much higher than .240 in the major leagues but the Marlins lack depth at catcher and Mack could be the team’s best option in 2025 and beyond.
The Next Five
Although these prospects do not crack the top 15, dynasty managers should keep their eye on these five players:
Jared Serna – 22 YO – An undersized middle infielder with average speed and a fine hit tool who should debut in 2025.
Dillon Head – 20 YO – A 2023 first-round pick who struggled with injuries this season and is best known for his speed.
Graham Pauley – 24 YO – An infielder who has put up solid minor-league numbers but has a suspect hit tool and major platoon concerns.
Dax Fulton – 23 YO – Lefty with good stuff, spotty control, and who has not pitched since 2023 after undergoing his second Tommy John surgery.
Victor Mesa Jr. – 23 YO – An athletic outfielder with hit tool concerns whose speed has slowed down as his power has developed.
