Fish On First Prospects Report: Pensacola adds another stud outfielder; Gage Miller's breakout year

For the 2026 season, Fish On First will provide weekly reports on the Miami Marlins farm system, covering all levels. Here's the first June edition of our Fish On First Prospects Report, which includes another wave of promotions and releases, plus the start of the Dominican Summer League campaign.

This report covers the games played from May 26-June 1.

Triple-A Jacksonville

As part of all the prospect promotions this past week, infielder Gage Miller was assigned to Triple-A. Selected in the third round of the 2024 MLB Draft out of Alabama, Miller was slashing .275/.368/.440/.807 with four home runs, 22 RBI and a 117 wRC+ in Double-A Pensacola. Through his first four games with Jacksonville, Miller is 6-for-17 with two doubles, one home run and five RBI.

Miller hit his first AAA home run on Saturday in the top of the second inning off Charlotte Knights starting pitcher Jonathan Cannon. The ball left the bat at 100.7 mph.

The 23-year-old has spent most of his career splitting time between second and third base. In releasing Cody Morissette on Tuesday, the Marlins are creating regular playing time for Miller to prove he can sustain this breakout season.

Promoted alongside Miller was Payton Green (Fish On First's No. 28 prospect). In 33 games with Pensacola, he slashed .240/.345/.470/.815 with four home runs, 10 RBI, 10 stolen bases and a 114 wRC+. Green is 3-for-17 with an RBI and five walks through four games.

Just like Miller, Green is 23 years old and has split time between third base and shortstop, with some second base sprinkled in there. He likely won't be called up this season, but he could set himself to be a non-roster invitee next spring and compete for a bench spot at the big league level.

In 17 games since he was optioned down to the minor leagues, Agustin Ramirez s hitting .284/.365/.486/.851 with four home runs and 11 RBI. Defensively he hasn't been showing much improvement, though.

Through his first six games with his new organization, Rece Hinds is slashing .318/.444/.500/.944 with one home run and two RBI. The Marlins acquired Hinds last week in a trade that sent reliever Zach McCambley to the Cincinnati Reds. Between both organizations, Hinds is slashing .308/.427/.607/1.034 with eight home runs, 22 RBI and a 166 wRC+.

The Marlins signed right-handed pitcher Amos Willingham to a minor league deal this week and he officially was activated. Willingham comes from the Houston Astros organization where in 11 appearances, he posted a 3.38 ERA, 5.09 FIP, 6.08 K/9 and 7.43 BB/9. He was released by the Astros on May 6. Willingham made his major league debut during the 2023 season with the Washington Nationals, but has not been back since.

Left-handed pitcher Christian McLeod is another new minor league free agent signing. He was recently promoted to Triple-A where in one appearance, he threw a shutout inning. In his first start with the Jumbo Shrimp, McLeod went three shutout innings, allowing just two hits and two walks while striking out one.

Ryan Gusto will pitch for the Marlins against the Washington Nationals on Tuesday. Through 10 Triple-A games (seven starts), Gusto has a 3.83 ERA, 3.51 FIP, 10.48 K/9 and 3.43 BB/9. The one previous appearance Gusto made at the big league level this season came on April 8 against the Cincinnati Reds, where he threw one inning, striking one out in the process.

Double-A Pensacola

Highlighted by a 23-run explosion in their game at historic Rickwood Field as well as the arrival of multiple top 30 organizational prospects, the Wahoos had a standout week against Birmingham as they split the series three games a piece. Pensacola is 26-25 on the season, two games out of their division lead.

Simply put with Fenwick Trimble, the guy just makes contact and gets on base. That was especially evident for the 23-year-old this past week when he went 10-for-29 with two homers and two doubles. This included a five-hit game during the aforementioned Rickwood Field contest. Not only were the five hits a personal record, it was the first such effort by a Pensacola player since 2023 when Dane Myers accomplished the feat. The performance was served as the exclamation point on an extremely solid month of May in which Trimble slashed .303/.345/.541.

Trimble keeps working counts well and continues to exhibit great barrel control to cover the entire plate and then some. As the season has gotten older, he’s started to force opposing pitchers into the zone by improving his plate discipline. There’s still a bit of improving to do for Trimble when it comes to pulling the trigger on pitches within the zone, but his whiff rate continues to diminish. Additionally, Trimble has also exhibited some surprising pop, particularly to his pull side. He’s gone that way with fly balls a solid 16% of the time. The one thing still absent from Trimble’s game is walks. He’s taken free passes at just a 7.5% clip.

Continuing to put his slow start behind him, Trimble is becoming a tough out and there’s still quite a bit more in the tank, especially if he can find the proper balance between patient and aggressive. He can play all three outfield spots but would be better served as a corner outfielder long term. Because of his solid contact rates, good speed and upside for at least average power, he’s an intriguing prospect trending in the right direction. A promotion to Triple-A could be in the cards for Trimble if this trajectory persists.

Speaking of players who put slow starts behind them in May, enter Cristian Hernández. After slashing just .164/.247/.205 in April, the 22-year-old infielder fully adjusted to life at the Double-A level. This past month, he hit a robust .360/.417/.560 with six doubles and three homers. Hernández's latest export was an 11-for-20 effort against the Barons.

Being humbled by a new league but then being able to adjust fairly quickly into the best version of yourself is no small task, but Hernández accomplished it with flying colors. His skill set is pretty enticing. At 6’2”, 200, Hernández is a good mix of hit and run. Touted highly for his bat speed, Hernández is another guy who can let the ball travel before committing to a swing. This past month, he started to show the ability to do so as well as the ability to be on time more consistently. After posting a 34% K rate in April, he shrunk that figure to 22% in May. The timeliness of his swings is also allowing him to tap into more power. Having entered the season never having topped seven home runs in a season, he’s already hit three.

On the bases, Hernández continues to exhibit plus speed, graded as high as 60 on the 20-80 scale. He’s already up to 13 bags on the year. Defensively, Hernández has the raw skills to stick at shortstop but many evaluators have at times questioned his repetition. That along with the fact that Aiva Arquette has now arrived in Beloit may have Hernández moving off shortstop to second base in both the short and long term. That move may be advantageous to allow Hernández to continue to focus on offensive sustainability. Another guy on an upward offensive trajectory with plenty of time on his side, the 22-year-old’s prospect stock is rising.

High-A Beloit

Riding high after winning five of six last week, it was a tough end to May for the Sky Carp who dropped four of six to Lake County at home. Pitching struggled in the series, allowing 34 runs. Despite only allowing hits at a .220 clip which is second lowest in the Midwest League, Beloit pitching has struggled keeping the ball in the park. Their 55 home runs allowed are third most on the circuit.

It’s been a disconnected season in terms of playing time already for Cam Cannarella due to a wrist injury he suffered in an outfield collision very early in the season. What hasn't been disconnected at any point though is his offensive production. Cannarella continued to absolutely punish High-A pitching in this series, going 11-for-27 with a triple, a home run, and eight RBI to earn our Prospect of the Week honors.

Even from a split lefty stance in which he steps towards the ball, Cannarella owns pretty quiet and smooth mechanics. His bread and butter tool is extremely quick hands which allow the ball to travel before he executes a line-drive swing with a bit of natural upper cut. Cannarella has seem High-A pitching extremely well, exhibiting one of the best whiff rates in the league. The only small downside to his approach has been a zone swing percentage slightly below league average. Cannarella hasn’t walked much, but his penchant for making contact at a well above average clip more than makes up for that. Contact-oriented with the ability to spray the ball to all fields and decent speed, Connarella profiles as a top of the order for-average threat long term with the chance to build into some more power. He can also hold down center field well and shouldn’t have an issue sticking there long term.

The only question is how will Cannarella fare against more advanced competition? We will start to get the answer to that question beginning this week as Fish On First has learned that the 22-year-old has been promoted to Double-A Pensacola. It will be interesting to see how reps are divided between Cannarella and the rest of Pensacola’s outfielders because all of them need and deserve starting reps.

For Cannarella specifically, he would advantageously continue to see reps in center field where his skill set will be of most value. If Cannarella can continue to show plus plate discipline and get on base against Double-A stuff, he will start to play closer to his ceiling of an every day outfielder. At the very least, he has a solid fourth outfielder floor.

After a rough start to the season in cold weather, Liomar Martinez finished off a solid month of May in grand fashion. Pitching into at least the fifth for a fourth time in five starts, the 20-year-old righty nearly completed a quality start, tossing 6 ⅔ frames of two run ball on just two hits and four walks. Martinez’s swing-and-miss stuff was on full display as he racked up a career-high 12 punchouts.

More consistently as the season progresses, we are seeing what Martinez can do when he has control with him. He’s a high-effort tosser, but he comes by good velo which has ticked up more this season. Sitting 93 last season, Liomar is more frequently hitting 94-95 mph and has been clocked as high as 97. He shows great confidence in the four-seamer particularly in elevating it to set up his best secondary, a high-70s/low-80s curveball with good shape and horizontal drop. This past season, Martinez added a sweeper which he’s made good strides with, quickly making it a usable third pitch. As his stuff improves, so too has his whiff rates. Boasting a 31.2% CSW%, he can make the opposition look foolish. Overall, though, it all comes down to repeatability and control. If what Martinez is currently doing can sustain, he has the ceiling of a back-end rotational piece. Because of the historic volatility with control, a future in the bullpen still seems more likely. Even if that is his floor, Martinez could carve out a solid career as a high-leverage arm—he already has the stuff and profile befitting of that role.

Low-A Jupiter

When the Miami Marlins gave nearly half of their entire international bonus pool money to Andrew Salas, they were expecting a player well beyond his years that can move quickly through the minor league system. So far, that has not been the case, slashing .168/.268/.245/.513 with two home runs, 16 RBI and a 50 wRC+. He is also striking out 26.7% of the time.

Only 18 years old, there is obviously still time for Salas to turn things around, but the early returns have not been encouraging at all. On Tuesday, he was demoted to the Florida Complex League.

Abrahan Ramirez has nothing left to prove at the Low-A level. He is now slashing .254/.366/.425/.792 with five home runs, 27 RBI and a 118 wRC+. Acquired in the Jazz Chisholm Jr. trade, Ramirez has always put up good numbers and so far, that continues to be the case.

Victor Ortega has emerged as the primary catcher for the Hammerheads. With multiple hits in five of his last eight games, the 22-year-old left-handed-hitter boosted his slash line to .265/.408/.422/.829. Behind the plate, he has committed only one error with no passed balls while throwing out 22% of base-stealers.

FCL Marlins

A perfect 4-0 week for the FCL Marlins saw the offense come alive, scoring 43 runs across four games. The week was highlighted by a 115 mph home run from one of Miami's offseason acquisitions, while the Dominican Summer League season got underway Monday with one of the organization's biggest international signings homering in his third professional at-bat.

The Marlins acquired Edgardo De Leon from the Cubs this offseason for one specific reason: his raw power. It was on full display last Thursday when he turned on a 97 mph fastball and launched it over the center field wall with an exit velocity of 115 mph.

Through 17 games, De Leon is hitting .267 with two home runs and 13 RBIs. More importantly, he has already drawn nine walks after drawing just 15 in 43 games last season, while striking out only 12 times. The power has never been in question, as he has flashed legitimate 70-grade raw power. If he can continue to improve his approach and keep the swing-and-miss under control, there is a lot to like in his profile.

For the second consecutive week, Luis Cova finds himself in this report, and rightfully so.

Although his 12-game hitting streak came to an end Monday afternoon, he has still reached base safely in every game this season. Last week, it was mentioned that the power production had yet to fully arrive despite the strong overall results. Cova answered those concerns this week, recording a two-double game and launching his second home run of the season.

The combination of consistent contact, on-base ability, and emerging power has just earned him a promotion to Low-A.

This week, Breyias Dean went 8-for-17 (.471) with two home runs and seven RBIs. Both home runs came in back-to-back games. Through 16 games this season, Dean is hitting .354 with a .604 slugging percentage and a 1.033 OPS.

One of the biggest developments in Dean's game has been the steady decrease in his strikeout rate. Since 2023, his strikeout percentage has ticked down little by little each season. Like many hitters in the Marlins system, limiting swing-and-miss will ultimately determine how far he can go. The tools have always been there, and if the improved contact skills continue, Dean could be in for a breakout season.

DSL Marlins & DSL Miami

With the DSL season having just begun on Monday, there is not much to report on yet. However, one of the Marlins' biggest international signings made an excellent first impression.

Signed for $1 million this winter, Ronny Muñoz entered professional baseball with some scouts questioning how his smaller 5-foot-10 frame would impact his game long term.

He wasted little time making a statement.

In the bottom of the sixth inning Monday afternoon, Muñoz launched his first professional home run in just his third career at-bat, giving the Marlins an early return on one of their biggest international investments of the 2026 signing period.
