Marlins Prospect Weekly: Compton's AA Demolition Rolls On, Dishmey Keeps Rewriting His Ceiling
By Eric Simmons ·
Marlins Prospect Weekly covers the last 7 days of action for the Marlins farm system.
No Signs of Slowing: Brandon Compton Is Breaking Double-A
Brandon Compton (AA, OF, Rank: 23) arrived at Pensacola with a .223 batting average from A+ Beloit and a profile centered on patience and left-handed power that scouts had flagged as real but unproven against upper-level pitching. What has followed is a month-long offensive outburst that has made those Beloit questions feel irrelevant. Over his last 30 days at Double-A, he is slashing .354/.456/.781 with nine home runs, 12 doubles, and 26 RBI across 26 games. This week he went 8-for-22 with six doubles, two home runs, and eight RBI, pushing his Double-A season line to .351/.435/.799 in 41 games. Combined across both levels, he owns 30 home runs, 86 RBI, and a .595 slugging mark in 101 games. The power grade is 55 and the raw has always been there; what Pensacola has revealed is that it translates against real arms.
The concerns on Compton are documented and fair. He is a 40 hit tool with 151 combined strikeouts on the season, a 58.2 percent contact rate, and a swing length that pitchers can exploit when they work up in the zone or attack with tight spin. None of that has gone away. But his 40-percent swing rate puts him firmly in disciplined territory, and the walk totals at both levels confirm the zone approach is not eroding under the weight of the swing-and-miss. He is a corner-only bat who will carry a left-field profile into the upper levels, which means the offensive bar is steep, and right now he is sprinting over it. A Triple-A assignment feels less like a question of whether and more like a question of when.
Back-End Tag, Front-End Results: Eliazar Dishmey Forces a Re-Evaluation
Eliazar Dishmey (AA, RHP, Rank: 44) entered the week with a combined 2.75 ERA and 0.99 WHIP across 20 starts at A+ and Double-A, and then went out and posted six innings of two-hit, one-run ball with eight strikeouts against a Double-A lineup. That outing fits neatly into what has been a dominant last 30 days: 23.1 innings, a 1.93 ERA, a 0.94 WHIP, and 37 punchouts at Pensacola, with a 36 percent whiff rate backing up the strikeout totals. For the season combined, he has 129 strikeouts in 95 innings with a sub-1.00 WHIP. The projection attached to his name is a long reliever or up-down arm, and he has been outrunning it for months.
The scouting picture has not changed dramatically: a two-seam/sinker package sitting 93-97 mph, two breaking balls that both flash average, a changeup that has developed enough to keep left-handers honest, and a command grade of 45 that reflects real walk totals. His season-long 44 walks are the part of the ledger that keeps the skeptics honest, because better lineups will eventually tax a pitcher who has to work from behind. His delivery is increasingly repeatable and the whiff rate at 35.1 percent is not a fluke, but the question of whether the secondaries have a true plus offering in the mix remains open. Back-end starter is very much alive as an outcome at this point, and I would take the over on that long-reliever projection given what the last month has looked like. He is 21 years old pitching well in Double-A; that demands a reassessment.
Quick Hits
- Deyvison De Los Santos (AAA, 3B, Rank: 34) · drove in five runs on seven hits, including two home runs and a double, across 23 plate appearances with four walks mixed in. His 60-grade raw power has been loudest over the last month: a .333/.413/.697 slash in 75 Triple-A plate appearances with seven home runs and an .697 slugging mark in that span. He has 18 home runs on the season at Jacksonville, up from 12 at Triple-A all of last year, and the improvement is real even if the swing-and-miss and defensive limitations keep the floor conversation alive. First base or DH is the realistic destination, and the bat is making that case.
- Liomar Martinez (A+, RHP, Rank: 46) · was the most dominant arm in the system this week: six innings, one hit, zero runs, zero walks, nine strikeouts. That outing brings his four-game last-30-day ERA to 4.05, but the WHIP of 1.05 and 28 punchouts over 20 innings in that stretch tell a more optimistic story. The season ERA of 5.74 at Beloit is the number that needs work, driven by 53 walks in 89.1 innings and a pitch-per-inning rate that reads inefficient. The 65-grade curveball is real, and his 34.2 percent whiff rate confirms it misses bats; the path to a mid-rotation ceiling runs through tightening command of the fastball and getting more from the changeup, but weeks like this one are what the projection needs to look less theoretical.
- Santiago Solarte (RK, SS, Rank: 52) · went 5-for-10 with a double, two RBI, and a hit-by-pitch in 10 plate appearances. For the season, the 17-year-old is slashing .339/.450/.598 with 10 home runs and 42 stolen bases in 52 rookie-level games, a line that is remarkable for his age even against DSL competition. The 65 raw power grade shows up in game results; the 44.9 percent contact rate does too, and that swing-and-miss is the volatility that comes with a big teenage leverage swing. He projects to third base long-term as the body fills out, but the production is doing everything the 65 power grade could ask for right now.
- Adrian Santana (AA, SS, Rank: 42) · went 9-for-23 with a double, three RBI, and two walks across 23 plate appearances in his second week with the Marlins after arriving from Tampa Bay in the August 3 trade. Since joining Pensacola, he is hitting .291/.371/.364 in 13 games at Double-A. He is a 65-speed, 60-field shortstop with a 20 power grade and the contact profile to match: 25 stolen bases on the season, 86.5 percent contact rate, and a strikeout total of just 32 across 317 combined plate appearances. The offensive ceiling is capped by the power deficiency, but the legs and the glove make him a legitimate utility floor.
- Juan Matheus (AA, SS, Rank: 38) · posted seven hits with a homer and four RBI across 22 plate appearances, continuing a strong month at Pensacola. He is hitting .309/.391/.423 over his last 30 days at Double-A with a contact rate of 81.9 percent that reflects a switch-hitting approach built more around putting the ball in play than punishing mistakes. His 15 combined home runs this season already exceed anything in his prior track record, and the 80.9 percent career contact rate travels. The projection is still a utility infielder whose value depends on the bat staying efficient.
- Luis Arana (A, SS, Rank: 37) · reached base five times in 27 plate appearances this week with eight hits, four doubles, and a pair of hit-by-pitches. The 18-year-old switch-hitter has 37 stolen bases combined across rookie ball and Jupiter this season while maintaining a 77.1 percent contact rate at Low-A. He is a 55 hit, 60 speed profile with modest power, and the development arc centers on incremental strength gains to add extra-base value to an already polished approach. The current production at A-ball at his age is ahead of schedule.
- Nate Payne (A+, LHP, Rank: 43) · struck out eight across 5.2 innings of one-run ball, the standout line from a week in which his secondary stuff clicked. His season ERA at Beloit sits at 3.81 with 103 strikeouts in 82.2 innings, and the 34.7 percent whiff rate over the last 30 days suggests the bat-missing ability is not seasonal noise. Walk totals remain the sticking point, with 15 free passes over his last 21 innings at A+, and the pitch-per-inning rate over that stretch pushes into inefficient territory. A back-end starter outcome is realistic if the command keeps moving forward; the stuff in his best outings is already good enough to deserve that conversation.
- Chase Jaworsky (A+, SS, Rank: 31) · went 5-for-16 with a home run and three walks across 16 plate appearances. Over his last 30 days he is hitting .381/.469/.571 with a contact rate of 80.9 percent, a meaningful uptick for a player whose season line sits at .220/.314/.310 through 229 plate appearances at Beloit. He is a 60 speed, 30 power bat with a utility ceiling, and the recent contact improvement matters more than the modest power output. The walk rate has been consistent all season; if the bat-to-ball quality holds at this level, the profile becomes more functional.
- Manuel Genao (A, RHP, Rank: 49) · threw 4.2 innings of one-hit, scoreless ball with seven strikeouts and two walks in his best outing in weeks. His season ERA at Jupiter sits at 3.78 with 106 strikeouts in 100 innings, solid numbers for a 20-year-old at Low-A. The walk rate has stayed manageable and the sinker-heavy approach generates enough weak contact to survive without a clear plus secondary. The changeup is still the development key; if it ticks into average territory, the back-end starter path becomes less speculative.
- Brian Sanchez (A+, LF, Rank: 63) · drove in seven runs on six hits with two home runs and two doubles across 21 plate appearances. The two homers push his combined season total to 11, against a 40 power grade, and the 14 RBI over his last 30 days show he is finding run-producing spots. His 70.5 percent contact rate is the part of the profile that bears watching as he moves through A+ competition, because when the bat-to-ball slips, the power grade alone will not carry a left-field profile.
- Victor Ortega (A+, C, Rank: 60) · earned his first promotion to A+ Beloit on August 18 after posting a .305/.458/.487 line with four home runs and 41 walks in 201 plate appearances at Jupiter. In his first two games at the new level, he went 3-for-9 with a double and two RBI across 13 plate appearances, drawing four walks in the process. The 34.7 percent swing rate and 83.6 percent contact rate from his A-ball season follow him to Beloit as the core of a patient, contact-oriented catching profile. The power ceiling is modest, but a catcher who gets on base at a .458 clip at any level earns the next assignment.
- Cam Kozeal (A, SS, Rank: 10) · landed on the seven-day injured list on August 18, his last appearance coming on August 15. He had gone 9-for-42 with two home runs in the 14 days before the placement across 10 games at Jupiter. Kozeal is the Marlins' top position prospect and the IL placement is worth monitoring, though no specific injury has been confirmed. He is hitting .214/.313/.405 through 48 plate appearances at Low-A this season, having started his A-ball career only recently.
- Dax Fulton (AAA, LHP, Rank: 27) · delivered four innings of two-hit, scoreless ball with seven strikeouts and two walks in his week's outing, a clean performance his season at Jacksonville has needed more of. His Triple-A ERA sits at 5.15 through 18 appearances, with a 1.58 WHIP that reflects the walk-rate issues that have followed him all year. The 65-grade curveball and mid-90s fastball are both present when the delivery repeats, and his last-30-day ERA of 3.00 in six outings shows he can string together quality stretches. After two Tommy John surgeries, durability and consistency remain the honest caveats on a profile that still carries a back-end starter ceiling.
