In addition to encouraging developments at the big league level, Marlins players are showing up more than they have in a long time down on the farm. With results and projection galore to marvel at, there is a lot to pick from in terms of who has stood out the most during the first half of the 2025 season.
After much deliberation, we have highlighted players at each position below, including several honorable mentions at the bottom. Some are still several years away from maturity, while others should be debuting in Miami before season’s end.
C Joe Mack
Current affiliate: Triple-A Jacksonville
Mack, pick 31 overall in the 2021 draft, came into pro ball from the high school ranks lauded for his defense with a bit to figure out on the offensive side of the ball. The glove allowed him to matriculate through a level a season through 2023, but he entered 2024 with a .217/.324/.303 slash line. This past season, amidst making the jump to Double-A where he was playing against average competition nearly three years his elder, Mack broke out with the bat. In 125 games, 112 with Pensacola, he slashed .252/.338/.468 with 24 home runs, fifth most amongst all MiLB catchers and one less than his future teammate Agustín Ramírez.
This season so far, not only has Mack proven 2024 was no fluke, he’s hitting even better. Through 73 games, the 22-year-old owns a .268/.344/.454 slash line. Currently, Mack is on a ridiculous 15-game run in which he has a 1.186 OPS. Almost all of this has happened at the highest level of MiLB with the Jumbo Shrimp. Seemingly the only potential knock on Mack’s performance is that most of his success has come at home in Jacksonville where the conditions vastly favor bats. Mack will have the rest of the season to even that out.

As he has his entire career, Mack is once again playing well under his average competition’s age this season—he’s nearly five years younger than the average AAA player. With continued success, Mack is on pace to take over as Miami’s everyday catcher in short order, possibly at the start of 2026. He will be 23 for all of next season.
1B Michael Snyder
Current affiliate: Double-A Pensacola
Snyder, who was drafted in the tenth round of the 2024 MLB Draft, has gotten off to a great start, slashing .247/.401/.388/.790 with six home runs, 47 RBI and a 133 wRC+. After spending most of the 2025 season in High-A, he received the promotion to AA, where in 18 games, he’s posted a 139 wRC+.
Snyder is one of the few qualified hitters in the system with more walks (57) than strikeouts (56).
2B Yoffry Solano
Current affiliate: FCL Marlins
Miami’s highest-priced international signing from the 2022 class ($750k bonus), Solano had a fine initial showing in the DSL, allowing him to make it stateside this past season. A minor injury in 2023 limited him to just 17 games that season, likely contributing to a slow start last year amidst the aforementioned stateside move. Solano finished that season well though, slashing .345/.400/.483 in the month of July, proving the rust was off and that he had begun adjusting to baseball in America. He also did it amidst making the full-time transition to second base where he fared well.
Solano is back in the FCL this season, building off of that late season success. Through 36 games, he’s slashing .270/.374/.357. He’s struck out just 24 times and walked 17 times. The glaring hole in Solano’s game is the lack of present power. Of his 34 hits this season, 27 are singles. His potential 60 grade hit tool, which he’s played into well this year, will be what carries him in his career, but he will need to at least start to find higher exit velocities and gaps to play towards a higher floor. Also, it would be encouraging to see him his use his 50-grade speed more. There’s still time for both of those things to happen. He probably won’t ever be a menacing physical presence in any sense of the word, but there’s still room for Solano to grow. He is still just 20 years old. It is very likely he will be moved to Jupiter to continue playing when the FCL season wraps up.
3B Diwarys Encarnación
Current affiliate: FCL Marlins
Encarnación, a signing from last year’s class, inked an undisclosed deal, which usually signifies the bonus was not substantial. In 2024, Encarnación played a full season in the DSL and slashed .227/.317/.301. This season, Encarnación, repeating the DSL, has produced a huge increase in power and exit velocities via physical projection. Through 33 games, the 19-year-old is slashing .305/.399/.534. His seven home runs are tied for second most on the DSL circuit.
“Credit to him and his offseason routine as well as our (player development) staff really getting him a lot stronger. He’s ticked up in a lot of areas and rightfully so has turned himself into one of our better position players in the DSL,” international scouting director David Hernandez told us recently. “He’ll almost turn 20 soon, but he’s performed his way into a promotion and has significantly improved in batted ball data as well as plate discipline from one year to the next.”
Positionally, the Marlins are still figuring things out with Encarnación: he has spent time at six different positions this season. If he sticks on the dirt, it will be at third base but at this point, it is more likely he moves to corner outfield spots. An improving mix of size and strength at 6’2”, 170, Encarnación is a bat-first prospect who should receive a stateside call in short order, likely when the DSL season concludes.
SS Payton Green
Current affiliate: High-A Beloit
Another 2024 draft pick out of Georgia Tech, Green is slashing .290/.364/.440/.804 with four home runs, 29 RBI and a 124 wRC+. Green has primarily played shortstop and should stick at the position moving forward. At 22 years old, a promotion to AA-Pensacola should be arriving shortly.
LF Fenwick Trimble
Current affiliate: Double-A Pensacola
Trimble had been rising quickly through the system. In High-A, he slashed .284/.407/.422/.828 with one home run, 14 RBI, 15 stolen bases and a 138 wRC+. When promoted to AA, Trimble hit one home run, but suffered a hamstring strain that sidelined him for nearly two months. He re-entered the Blue Wahoos lineup on Saturday.
Trimble has been getting occasional reps at each of the three outfield spots.
CF Jakob Marsee
Current affiliate: Triple-A Jacksonville
At this point, it isn’t a matter of if we will see Jakob Marsee don the Marlins uniform; it is a matter of when Marsee will be making his Major League debut. Through 88 games, Marsee is slashing .242/.375/.426/.800 with 12 home runs, 34 RBI, 42 stolen bases and a 122 wRC+. Marsee’s ability to get on base and cause havoc on the basepaths has been impressive. One major improvement has been elevating the ball higher, leading to increased power and the ability to utilize the entire field.
RF Kemp Alderman
Current affiliate: Double-A Pensacola
Alderman had a rough 2024 season, adjusting to a full slate of games in full-season ball. He was assigned to repeat Jupiter to start the season. Two months in, a hamate bone injury landed him on the IL for nearly two months. Alderman’s overall numbers in his second stint with Jupiter were solid and earned him a call to Beloit in August. There, he hit .240/.312/.344 in 33 games. Attempting to lengthen his season and make up for missed reps, the Marlins assigned Alderman to Double-A for the Southern League playoffs and then assigned him to the Arizona Fall League.
Alderman got his swag back in the hitter-friendly Fall League, hitting six home runs in just nine games and earning a Fall-Stars Game selection. Back fully healthy this season, the 22-year-old has been Pensacola’s most consistent offensive performer. Through 76 games, he’s slashing .281/.332/.431 with 9 home runs, already a career high. He’s another bat-first guy, but the onset of loud offensive tools at the upper levels should keep him in the conversation for a debut as early as next year.
DH Troy Johnston
Current affiliate: Triple-A Jacksonville
In true Johnston fashion, it’s been yet another very productive season so far. Seventy-six games in, he’s staring another 20-20 season directly in the face for the playoff-bound Jumbo Shrimp. Other than the time missed away from the team for the birth of his first child, Johnston has been in lineup nearly every single game for Jacksonville. He’s played left field, first base and DH. On most occasions, the veteran minor leaguer has been asked to set the tone for the Jumbo Shrimp lineup. When leading off, Johnston is slashing .262/.333/.536. He has 10 home runs and 28 stolen bases.
Why Johnston, the 2023 MiLB Player of the Year, has yet to be called upon to contribute to the major league team, the world may never know. In his last year of team control before hitting minor league free agency, hope is that step will be taken for a scientific and crafty lefty hitter and tenacious athlete who has given most of his life to the organization for upwards of seven years.
SP Robby Snelling
Current affiliate: Triple-A Jacksonville
The recently promoted Robby Snelling has been great this season, completing seven innings of work twice and in AA, posting a 3.61 ERA, 2.90 FIP, 10.58 K/9 and a 2.74 BB/9. Of note, his fastball velocity has risen compared to 2024, more consistently touching mid 90s when he needs it.
In a pair of AAA starts this season, Snelling has logged nine innings and allowed only two runs.
RP Nigel Belgrave
Current affiliate: Double-A Pensacola
Belgrave has been unhittable this season, posting a 1.58 ERA, 2.53 FIP, 12.60 K/9 and 3.60 BB/9 through 23 appearances. He last surrendered an earned run on June 5.
It was a decision between Josh Ekness and Belgrave to earn the honor, but Belgrave has been far more consistent and should receive the promotion to AAA soon.
HM Anthony Abreu
Current affiliate: DSL Marlins
Abreu is an international signing from this year’s class who has shown immediate results. The 17-year-old has put out six home runs, something pretty rare from a debuting DSL prospect. Overall, Abreu is slashing a robust .235/.395/.500. In addition to the power potential, Abreu is holding down a respectable 45/22 K/BB.
A lefty-hitting, righty-throwing 6’1”, 180 corner outfielder, Abreu appears ahead of the curve already in terms of developed tools. The Marlins think this may be the peak of Abreu’s development physically, and he also owns a defensive profile that will likely move him to a corner outfield spot. That said, the already-loud offensive tools and plenty of time for projection should carry Abreu to a very solid floor. He will very likely come stateside next season.
HM Colby Shade
Current affiliate: High-A Beloit
Shade, 24, is a bit old for his current level which he is repeating after spending 33 games in Beloit last season, but his improvement deserves credit. Drafted in 2024 and moved from Jupiter to Beloit mid season, Shade is slashing .261/.380/.374 so far this season. After stealing 45 bases last year, he is already at 39 with nearly two full months left.
a0REUldfV0ZRVkV3dEdEUT09X0Fna0NVd1lOQTFNQVhWVlJVd0FIVWdjRkFGa05CbGNBQWdBRkJRTlVCRllBVlF0Ug==.mp4
Shade owns a hit-over-power profile, but he’s been able to find some gaps and let his speed go to work for him. He has doubled 12 times and recorded four triples. Shade has also shown good patience against A+ stuff. He owns a 13.2% walk rate.
Defensively, Shade has the plus speed and good-enough arm to stick in center field. He should’ve been called up to Pensacola yesterday to see if his offensive profile can keep pace against upper minors pitching.
HM Thomas White
Current affiliate: Double-A Pensacola
White just keeps shoving. A top prospect in the organization and top 30 prospect league wide, the 6’5”, 240 lefty was a force to start the season at High-A (2.80 ERA and 53/17 K/BB in 35.0 IP) and continues to be amidst his recent call to the upper minors. He’s current holding down an even 3.00 ERA in his first 15 innings with Pensacola. During the All-Star break, White participated in his second straight Futures Game.
The Marlins are, somewhat understandably, taking White’s progression very slowly. This season, he has only been allowed to pitch more than four innings three times. On almost every occasion, he is being limited to 85 pitches. That said, White’s insurmountable stuff has played up well to Double-A hitters. He is sitting 95 and has been as high as 99 with his fastball while intermixing a plus-plus power curve and plus changeup all from a high deceptive arm slot. He masks his smooth release well and garners the ability to make hitters look foolish.
The next step for Thomas is to have the reins taken off and be allowed to go deep into games. As long as the stuff and velo persists into later innings and third time through lineups, he will be on track to make a major league debut next season. He will turn 21 on September 29.
