The Marlins have one of the more exciting dynasty managers to follow. At the top, they have two of (if not the) best left-handed pitching prospects in all of baseball. With Robby Snelling and Thomas White leading the way, they have multiple hitting prospects who are ready to make an impact as early as 2026. This system is deep for both hitting and pitching prospects with plenty of upside. Keep reading for the full list of Miami’s top 20 dynasty prospects.
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 here.
Top Marlins Prospects
The Top Tier
1) Robby Snelling – SP, 21 YO
2025 Stats (AA/AAA): 136.0 IP | 2.51 ERA | 30.3% K% | 7.1% BB%
Robby Snelling’s dynasty value has bounced around over the course of his professional career. Taken 39th overall by San Diego, Snelling’s professional career got off to a fast start. The early concern was that he lacked a third offering to keep righties at bay. Then, Snelling lost some of his fastball velocity and struggled before being traded to Miami. Miami’s pitching development is some of the best in baseball, and not only did they fix his velocity issues, but they also helped him develop more feel and consistency on his changeup. Snelling looked like a more complete pitcher than he even did early in his career, and the results speak for themselves. Snelling’s numbers look even if you only look at his 11 Triple-A starts. There, he posted a 1.27 ERA with a 32.9% strikeout rate.
Snelling is on the verge of a major league debut. This should come early in 2026, and all fantasy managers should be prepared. Snelling’s four-seamer sits in the mid-90s but gets excellent run up in the zone. His command and feel for his curveball are excellent. The pitch is not only a plus strikeout offering, but also a pitch Snelling will throw in any count. He places a heavy reliance on his changeup against righties. In Triple-A, righties hit just .167 off the pitch with a 35% whiff rate. Snelling’s plus command and control give him a stable floor, while the continued development of his arsenal has turned him into a premier pitching prospect for dynasty managers.
2) Thomas White – SP, 21 YO
2025 Stats (A+/AA/AAA): 89.2 IP | 2.31 ERA | 38.6% K% | 13.6% BB%
The Marlins went pitcher-heavy with their first two picks in the 2023 draft. Noble Meyer was taken first, and then the team selected Thomas White with the 37th overall pick. The 6’5″ hurler has quickly established himself as one of the premier left-handed pitching prospects in all of baseball. After striking out 29.2% of batters in his first full professional season, White increased his strikeout rate to 38.6% last year. This spike in strikeout rate is on the back of a few excellent pitches. White’s fastball sits in the mid-90s and gets good ride with late life. The pitch generates plenty of whiffs and projects to be a plus offering. Where White really makes his money is with his sweeper/slider combination. The softer sweeper sets up his harder gyro slider, which is the best pitch in his arsenal. The combination of both gives him significant strikeout upside.
Based on pure upside, White would rank above Snelling on this list. His low-effort wind-up combined with big-time stuff is a dynasty manager’s dream. However, White’s consistency is still a work in progress. His 3/4 release point can get a bit inconsistent at times and varies from pitch to pitch. This has led to high walk rates throughout his professional career. White will need to improve upon his 13.6% walk rate from last season to reach his true ceiling. If he does, White has SP1 potential and will be a dynamic fantasy asset.
3) Aiva Arquette – SS, 22 YO
2025 Stats (A+): .242 AVG | .350 OBP | .323 SLG | 1 HR | 7 SB | 23.1% K% | 14.5% BB%
After playing two years at Washington, Aiva Arquette transferred to Oregon State for his final collegiate season. With the Beavers, Arquette hit .354 with 19 home runs en route to being selected seventh overall by Miami in last year’s draft. The tall 6’5″ shortstop has incredible raw tools and projection. Despite his size, Arquette moves well with above-average speed and instincts. There is a chance he could slide over to third base long term, but his bat will play for fantasy managers regardless of where he ultimately winds up.
The first note that I wrote down while watching Arquette’s film was “he looks like the real deal”. Sometimes, it can really be simple enough to leave it at that. Arquette has a smooth and easy swing with lightning-quick hands. He controls both the barrel and the strike zone well with great plate coverage to all fields. His power projection is what should have dynasty managers excited. Getting Arquette to tap into his pull side more could unlock 35+ home run game power. There is significant upside here for dynasty managers and Marlins fans to get excited about.
4) Kemp Alderman – OF, 23 YO
2025 Stats (AA/AAA): .285AVG | .338 OBP | .482 SLG | 22 HR | 22 SB | 23.1% K% | 7.3% BB%
Looking at Kemp Alderman’s stat line from last season, you would not guess that FanGraphs gives him a 30 grade for both his hit tool and speed. The former second-round pick put together a breakout season in 2025. The raw power that Alderman flashed during his time at Ole Miss showed up in a big way last season. The 6’2″ outfielder has effortless power. His stance is simple. A small leg kick and quick hands are all Alderman needs to drive the ball out to any part of the ballpark. Ten of Alderman’s home runs came in his final 128 plate appearances. That is a 47-homer pace for those tracking at home. His power and proximity to the major leagues give Alderman significant fantasy and dynasty appeal moving forward.
Back to his hit tool and speed, Alderman is still far from a perfect dynasty prospect. Yes, he stole 22 bases last season, but he does not project to be a prolific base stealer at the major league level. Alderman was caught 10 times last year and should settle into the 10-15 steal category moving forward. As for his hit tool, there is some risk here. Alderman is an aggressive swinger who lacks great pitch recognition. Alderman punishes mistakes, especially fastballs, but also posted concerning whiff rates against breaking balls last season. His .285 batting average was largely driven by a .336 BABIP, which is likely to regress at the major league level. His full-time projection falls into the realm of a .240 hitter with 25-30 home runs and 10-12 stolen bases.
5) Noble Meyer – SP, 20 YO
2025 Stats (A+): 65.1 IP | 4.41 ERA | 24.3% K% | 12.8% BB%
While fellow 2023 draftee Thomas White has risen to become one of the game’s top pitching prospects, the progression for the team’s first pick from 2023 has not been as successful. Noble Meyer has struggled to find consistency throughout his first two seasons of professional baseball. The 6’5″ righty has posted strong strikeout rates, but high walk rates have prevented him from making it past High-A up to this point. The timing and consistency in his delivery can be off at times, which has led to erratic control. Developing more consistency will be necessary for Meyer to live up to the expectations of being the 10th overall pick.
Despite his high walk rate, Meyer still ranks as Miami’s fifth-best prospect. Progression is not always linear, and Meyer has the pure stuff to turn things around. His fastball is more of a sinker than a true four-seamer, but the pitch sits in the mid-90s and gets good arm-side run. Where Meyer really excels is with his breaking stuff. Both Meyer’s slider and changeup project as plus offerings. His slider generates elite spin rates and has big-time sweep and dive away from righties. The upside and draft pedigree are still present for Meyer. He remains a prospect that dynasty managers should have on their radar.
6) Andrew Salas – 2B/OF, 17 YO
2025 Stats (A): .186 AVG | .319 OBP | .245 SLG | 3 HR | 39 SB | 24.3% K% | 15.9% BB%
Andrew Salas is extremely raw still. The 17-year-old is the younger brother of Ethan and Jose Salas and signed with the Marlins last January out of Venezuela. Salas is a lanky 6’2″ with plenty of room to add muscle and bulk up. Right now, his power is well below average, but at 17, there is plenty of time for this to change. The development of his power will ultimately determine his long-term dynasty outlook.
Despite the significant physical development required, Salas still ranks sixth thanks to his innate baseball instincts. Having skipped the DSL and Complex League, Salas was thrown right into the fire of full-season ball. While the batting average does not look good, his contact skills and strike zone understanding proved to be years beyond his age. Salas hits a lot of line drives and gets to his pull side well already. His hit tool projects to be a plus attribute (once his .253 BABIP improves), and he is a plus runner with great speed. Even if Salas adds more muscle to improve power, he still will have 25+ stolen base upside. Salas’ ranking is about projectability. He is far from a finished product, but he has the raw skills to skyrocket up lists next season.
7) Joe Mack – C, 23 YO
2025 Stats (AA/AAA): .257 AVG | .338 OBP | .475 SLG | 21 HR | 9 SB | 27.1% K% | 9.6% BB%
At some point in 2026, it is likely that Joe Mack will take over as Miami’s everyday catcher. Taken 31st overall back in 2021, the path to Triple-A has been slow and steady for Mack. As is the case with most prep catchers, development is slower than at other positions due to the demanding nature of the defensive position. Defensively, Mack is an excellent backstop. His defensive skills are likely to get him to the major leagues, but his offensive production in 2025 is what has dynasty managers excited. Over the past two seasons, Mack has emphasized tapping into his pull-side pop, which has increased his home run projections moving forward.
Mack’s power production primarily comes off of fastballs. He does a great job of getting around on them and driving them out to left field. The concern is how Mack will fare against other pitches. During his time in Triple-A last season, Mack whiffed at least 40% of the time on all breaking/off-speed pitches. Mack is a free swinger with below-average plate discipline and contact skills. This is likely to get him in trouble against major league pitchers and could limit his future fantasy production.
Prospects Dynasty Managers Should Know
8) Cam Cannarella – OF, 22 YO
2025 Stats (A+): .284 AVG | .337 OBP | .375 SLG | 0 HR | 1 SB | 18.9% K% | 7.4% BB%
The left-handed hitting outfielder was viewed as one of the better defensive outfield prospects in the 2025 draft. Cannarella hit well in all three seasons at Clemson, although the power and stolen base numbers do not do much in terms of excitement for dynasty managers. Despite the lackluster home run and stolen base outputs, Cannarella has an intriguing skillset for dynasty managers to consider. Cannarella is a great athlete with good speed, which could translate to more stolen base totals than he has shown. He also has excellent bat control. He will never hit 30+ homers, but he projects to be a doubles monster and solid real-life player for the Marlins.
9) Kevin DeFrank – SP, 17 YO
2025 Stats (DSL): 31.0 IP | 3.19 ERA | 24.1 K% | 7.1 BB%
Kevin DeFrank does not look like he is 17 years old. Standing tall at 6’5″, DeFrank is already relatively filled out. DeFrank signed with Miami out of the Dominican Republic last January. In the limited film on DeFrank, there are aspects of his game that resemble those of a 17-year-old. DeFrank’s windup is a bit all over the place and lacks consistency. He bends back throughout his motion, which projects to lead to some control issues. Even with areas for development, DeFrank’s pure stuff lands him at ninth overall. According to reports, DeFrank’s fastball velocity already sits in the mid-90s. His sweeper gets really good movement away from righties. DeFrank’s changeup is also praised as a plus offering. There is plenty of time for DeFrank to develop into a significant dynasty prospect. Still years away from the major leagues, he is a player to keep close tabs on in 2026.
10) Drew Faurot – 2B, 22 YO
2025 Stats (A): .341 AVG | .392 OBP | .477 SLG | 0 HR | 5 SB | 19.6% K% | 8.2% BB%
The Marlins selected Drew Faurot in the fourth round of the 2025 draft. The 6’3″ Florida State product saw time at short, third, and second in his professional debut season, although his most likely home is at second base. Faurot handles the bat well from both sides with plus power upside. His swing can get long at times, and he is susceptible to velocity up (especially from the left side), but Faurot’s hit tool has improved a lot since his freshman year of college. The Marlins would be wise to adjust his swing to get more lift to help unlock his power. If they can do that, his dynasty ceiling will rise significantly.
11) Karson Milbrandt – SP, 21 YO
2025 Stats (A/A+/AA): 90.0 IP | 3.00 ERA | 29.0% K% | 12.3% BB%
Drafted in the third round back in 2022, Karson Milbrandt has shown significant flashes of relevance over the past few seasons. His arsenal is headlined by an explosive fastball. The pitch sits in the mid-to-upper 90s, has great late ride, and has significant arm-side run. His violent arm action, paired with the velocity, makes the deception of his off-speed pitches even greater. The issue thus far in Milbrandt’s career has been control. He has posted high walk rates throughout his professional career and fails to generate the chase rates his stuff suggests. He has the pure stuff to rank higher on this list, but settles in at 11 now based on the significant risk still apparent.
12) Liomar Martinez – SP, 20 YO
2025 Stats (A): 101.0 IP | 3.30 ERA | 28.1% K% | 9.7% BB%
One of the nastiest curveballs in Minor League Baseball belongs to Liomar Martinez. The big 12-6 bender generates over 2,700 RPMs of spin on it. He generates whiffs at a high rate and showed improved command over the pitch in 2025. Improved control was the story of 2025 for Martinez, who lowered his walk rate from 16.6% in 2024 down to 9.6% in 2025. Martinez also mixes in a sharp gyro slider to help generate whiffs. Already one successful season in Low-A, Martinez does not turn 21 until next June. He will need to show more consistency with the location of his sinker down in the zone, but his two secondary offerings give him a promising base in an organization developing pitching prospects at a high rate.
13) PJ Morlando – OF, 20 YO
2025 Stats (CPX/A): .215 AVG | .371 OBP | .332 SLG | 5 HR | 8 SB | 27.4% K% | 17.6% BB%
PJ Morlando really just needs to stay healthy at this point. When the Marlins took Morlando 16th overall, the belief was that with professional development, Morlando had the tools to turn into a star. He is a plus fielder with okay speed, but his power is substantial. Morlando flashed this power with five home runs in 2025, but was once again limited to only 58 games due to injury. He still possesses the tools to turn into a fantasy-relevant dynasty prospect, but he has yet to prove he can handle professional competition. Hopefully, Morlando stays healthy and rises up this list in 2026.
14) Andres Valor – OF, 20 YO
2025 Stats (A): .231 AVG | .335 OBP | .372 SLG | 9 HR | 45 SB | 29.0% K% | 11.0% BB%
The dynasty potential here is tantalizing. Valor has all of the tools you look for in a breakout dynasty prospect. He is young, projectable, and has an exciting set of tools. Valor is blazing fast on the bases and easily projects as a 35+ base stealer. He also has a good feel for getting to his pull side and has the frame projection to turn his size into plus raw power. Valor has shown flashes of improving his hit tool, while also making adjustments to his swing and stance, but has failed to find consistency up to this point. His ceiling earns him a ranking of 14th, even if the stats do not back it up quite yet.
15) Diwarys Encarnación – 3B, 20 YO
2025 Stats (DSL): .291 AVG | .398 OBP | .484 SLG |8 HR | 25 SB | 13.9% K% | 12.5% BB%
Diwarys Encarnacion is not going to generate much fantasy attention because he just turned 20 years old and has not advanced past the DSL. However, in his second DSL season, Encarnacion showed major improvements while flashing intriguing dynasty potential. The 6’2″ third baseman showed off great plate discipline, improved contact skills, plus speed, and a feel for pulling the ball in the air. Encarnacion needs to show he can handle full-season competition, but his skillset is worth dynasty managers keeping an eye on next season.
The Next Five
Although these prospects do not crack the top 15, dynasty managers should keep their eyes on these five players:
Starlyn Caba – 20 YO – An undersized shortstop with good contact skills, plus speed, and an excellent glove, but little to no power projection.
Deyvison De Los Santos – 22 YO – The slugging corner infielder has stalled out in Triple-A due to the inability to improve his hit tool—projects as a AAAA player.
Dax Fulton – 24 YO – A left-handed pitching prospect with a plus curveball and a mediocre fastball, Fulton has struggled with control since reaching Double-A and projects as a back-end swing starter.
Luis Cova – 18 YO – A toolsy outfield prospect who performed much better in his second stint in the DSL, showing off plus plate discipline, good speed, and subtle power upside.
Max Williams – 21 YO – The team’s third-round pick from 2025 has plus raw power, but a unique stance could hinder his ability to hit professional pitching.
