Fish On First Prospects Report: Eliazar Dishmey emerging as impact arm; dominant DSL hitters

For the 2026 season, Fish On First will provide weekly reports on the Miami Marlins farm system, covering all levels. This is the first check-in that incorporates both new draft picks and prospects acquired by the Fish on trade deadline day.

This report covers the games played from August 4-10.

Triple-A Jacksonville

The Miami Marlins were busy during the trade deadline conducting five trades. Of those trades, Brayden Taylor (Hicks trade), Jonathon Long (Braxton Garrett trade), Jace Beck (Braxton Garrett trade) and Brandan Bidois (Lake Bachar trade) joined the Jacksonville Jumbo Shrimp. The only player who has not played is Brandon Bidois because he is on the seven-day injured list.

Taylor, a first-round pick back in 2023, spent the entire 2026 season at the Double-A level in the Rays organization. In 88 games, he slashed .284/.384/.513/.897 with 17 home runs, 56 RBI, 20 stolen bases and a 136 wRC+. So far, Taylor has played in five games at the Triple-A level, where he has yet to record a hit, but has walked seven times, driven in a run and scored one as well.

Long likely was not going to be called up in the Cubs organization, so instead, he is traded to Miami. With the Cubs Triple-A affiliate, Long played in 99 games where he hit .283/.364/.455/.818 with 12 home runs, 62 RBI and a 108 wRC+. Right before joining the organization, Long was named International League Player of the Month. With the Marlins, he has played in 5 games, where he is 5-for-17 with two RBI. He has split time between the outfield and first base.

Beck is a 26-year-old right-handed pitcher. The Cubs used him primarily in relief, but in his Marlins organizational debut, they had him start Sunday's series finale against Gwinnett. He tossed five no-hit innings, striking out five and not allowing a walk. It was not a perfect game because of an error committed by the Shrimp in the game. Beck was named International League Pitcher of the Week.

As for Bidois, he is the only one with major league experience, appearing in 15 games and posting a 6.32 ERA, allowing 16 runs (11 earned) on 19 hits (five home runs). In 20 innings pitched for the Pirates Triple-A affiliate, he had a 8.10 ERA, 6.09 FIP, 11.70 K/9 and 7.65 BB/9.

When it comes to players who were with the Marlins organization before the trade deadline, Gage Miller continues to succeed in Triple-A, now having played 34 games. He is slashing .314/.454/.589/1.022 with six home runs, 21 RBI and a 172 wRC+. With the recent trades of both Connor Norby (Rockies) and Jacob Berry (Royals) and call-up of Graham Pauley, Miller's reps should be increasing down the stretch.

Double-A Pensacola

The Wahoos kept rolling in the second half, taking four of six against Montgomery, their third straight six-game series win. This included a thrilling extra innings walk-off victory on Friday. Pensacola is 23-16 since the break, pacing their division. They rank near the top of the entire Southern League in many stat categories, including home runs (second) and OPS (third). With the impending returns of Aiva Arquette on Tuesday and Dillon Lewis possibly the week after, the stretch run looks promising.

Another start, another impression made. Eliazar Dishmey kept his roll of extremely positive starts going this week with perhaps his best outing of the campaign, a six-inning shutout performance in which he struck out 10. In his last six starts, the 21-year-old and our Prospect of the Week has a 0.33 ERA.

Dishmey continues to live off of fantastic fastball command and the ability to change eye levels then set up a wide secondary arsenal. He can induce groundouts with his sinker and has gained a good feel for the Marlins’ archetype gyro slider that he added this season. He also throws a plus curveball and a still-improving changeup. Coming into the year, Dishmey lacked pure swing-and-miss stuff and was more of a pitch-to-contact arm pinned for future relief work. His newfound ability to garner whiffs via this widened arsenal has raised his ceiling and made him one of the best righty weapons in the Marlins organization. There’s also still time on his side as he’s pitching at Double-A at age 21, nearly four years younger than league average competition.

Dishmey isn’t spoken about much nationally, making him a very under-the-radar name. But if this current run extends, that should soon change. Currently the owner of a 114/42 K/BB, he’s been one of the best kept secrets in MiLB. Dishmey should receive an invite to big league camp next season.

Speaking of good impressions and great fastball command, Jacob Kisting is another guy who did both on the mound this week. Part of the return from Tampa Bay in the Liam Hicks trade at the deadline, the righty made his organizational and Double-A debut. He showed very well, working five scoreless innings on four hits and eight strikeouts.

New to the pitching craft overall as a converted infielder and especially new to starting having been built up to do it by the Rays this year, this went about as well as Miami could have hoped in Kisting’s first Pensacola start. He sat 93-94 with the fastball which he used very frequently and topped at 97. His offspeed offerings—he throws both a splitter and kick change—sat 85-87, showed great late arm-side fade, played well off of the heat and garnered him three of his eight punchies. Kisting also mixed in a slider, which is still a work in progress.

Overall, Kisting profiles as a zone pounding strike-thrower who is proving he has the ability to be economical with pitches and work multiple innings. His ability to stick as a starter will rely heavily on his ability to continue to refine his breaking ball and keep hitters off balance. At the very least, the Marlins got a future MLB reliever here.

High-A Beloit

A solid week for Sky Carp starting pitching couldn’t be backed by offense as they dropped four of six to Wisconsin. Beloit’s .347 OBP is the second lowest in the Midwest League.

After a very slow start to the season, a trip to the development list has seemed to make all the difference in the world for Jacob Jenkins-Cowart. A sub-Mendoza line .200/.240/.343 bat in the first half, the 2024 eighth-rounder was given a week off at the end of June. Since returning on June 30, he is slashing .272/.326/.568. That includes a 5-for-10, two-homer showing this past week.

Been a solid second half for Jacob Jenkins-Cowart. This is his seventh homer since being activated from the development list on June 30th.#Marlins pic.twitter.com/BSHOsfInK9

Cowart is a large physical specimen with a lot of moving parts which in the past, led to a lot of off balance and long swings. Since his return from the dev list, he has adjusted his stance and upper body to lean out over the plate with his arms further away from his body. This has allowed Jenkins-Cowart to make more contact, particularly on pitches on the outer half.

The strikeout susceptibility is still present for Cowart, who maintains a long uppercut stroke and who shows particularly struggles against plus breaking stuff, but he has started to walk slightly more in July and August. The recent power binge (seven HR in 27 games) is definitely encouraging, but Jenkins-Cowart will need to continue to take positive strides in lengthening at-bats and shortening up his stroke if he hopes to make it, especially in a Marlins system stacked with lefty-hitting outfielders.

A shoulder injury caused 2025 third-rounder Max Williams to miss about half of the minor league season, but in terms of his bat, it's been all gas, no brakes since his launch last month. A jump to Beloit last week also hasn’t slowed Williams: he’s off to an 8-for-29 start with Beloit, including 6-for-22 this past week. In 87 ABs, Williams has already recorded 11 extra-base hits. Still not ready to throw, Williams has been a full-time DH since his return.

At 6’2”, 207, Williams isn’t the largest physical specimen, but he packs a punch with quick wrists and a violent swing. Against Low-A stuff, Williams also showed good selectivity and patience, walking nearly as much as he struck out. If that can maintain as the quality of stuff he’s facing increases, he will be yet another 2025 draftee to follow closely. With a plus arm, he profiles as a future 7 or 9 guy on the outfield grass.

Low-A Jupiter

Jacob Lombard started his professional career with a bang by homering in his Low-A debut last Tuesday. In five games, he is slashing .211/.375/.368/.743 with one home run, two RBI and a 109 wRC+. Lombard has played both shortstop and second base. The only other draftee to have made his pro debut is third-round pick Cam Kozeal, who in five games is slashing .273/.385/.318/.703 with one RBI and a 102 wRC+.

Acquired as one of the pieces in the Jake Burger trade, Echedry Vargas started his first year in the Marlins organization at the High-A level, posting a 66 wRC+ in 82 games at that level in 2025. To begin the 2026 season, he dropped down a level to Low-A, where in 82 games he is slashing .302/.353/.534/.886 with 16 home runs, 62 RBI and a 128 wRC+. Regardless of the player's circumstances, hitting for so much power in the Florida State League is rare. It is now about showing that he can produce at the High-A level.

Andrés Valor is on his way to leading the Marlins system in stolen bases with 47 so far. Despite a high 31.8% strikeout rate, he is slashing .223/.346/.407/.752 with 13 home runs, 43 RBI and a 104 wRC+.

Elier Morillo continues to be a strikeout machine, posting a 16.69 K/9, but the walks continue to rise, now at 7.63 BB/9. In 18 appearances, Morillo has a 4.12 ERA and 4.07 FIP.

DSL Marlins & DSL Miami

After hitting a home run in back-to-back games, including Monday afternoon, Carlos De Los Santos has been promoted to the DSL Marlins, according to the transaction logs. De Los Santos has been on fire from game one and doesn't look like he is slowing down. He is now hitting .375 on the year in 120 at-bats with a .461 OBP.

Jesús Pérez has seen a huge decrease in walks and an increase in strikeouts, but that has not stopped him from putting together a solid season nonetheless. In 100 at-bats, he is hitting .300 with three home runs. He has already hit eight doubles this year, compared to just one double and four home runs last year. Pérez's OPS is 120 points higher than it was last year, and he has also significantly decreased his ground-ball percentage.

Angel Bonilla has primarily been used as a pinch-hitter this season, but he has always been ready when his name is called upon. In a small sample size of 27 at-bats, Bonilla has two home runs, while walking at a 26% clip, helping push his OBP to .412. Bonilla has also shown that he doesn't strike out often, posting a 15 K%, while most of his batted balls have been in the air. It's hard to put two and two together with such a small sample size and limited data, but those two things sticking out certainly make Bonilla an intriguing player to keep an eye on.

Diego Martinez has shown a very good power surge in his first professional season. In just 63 at-bats, he has four home runs, including one on Monday afternoon. On top of that, he has shown flashes of speed with eight stolen bases. Martinez has primarily been used at catcher and first base, and in 98⅓ combined innings, he has made zero errors this season.

If the DSL had a Most Improved Player award, Johan Machado would be the favorite to win it. On top of that, he could be in consideration for DSL MVP.

Machado was selected to participate in the league's All-Star Game on July 19, but his production actually spiked after receiving that recognition. After hitting .237 in June, Machado followed that up by hitting .342 in July and is now hitting .440 so far in August, bringing his season average to .319. He hit two more home runs Monday afternoon, bringing his season total to nine.

Raunny Figueredo was just added to Fish On First's Top 30 prospects, slotting in at #29, and no one deserved it more than Figueredo. After finishing July scorching hot, he has not slowed down. He is hitting .381 this month with a home run and eight RBI, and in 21 at-bats, he has yet to strike out. His average is now up to .299, to go along with five home runs, 39 RBI and 15 stolen bases. He also has five assists in 43 games as a right fielder.

Santiago Solarte slotted in at #16 in the FOF Top 30, and it won't take long until he continues climbing the rankings. Despite being hitless in his last three games, Solarte recorded a multi-home run game earlier this week, bringing his season total to nine. His average is now .315, with an elite .428 OBP and .990 OPS. The stolen base number continues to increase by the day as well, and it is now up to 37.
