Marlins Prospect Weekly: Compton's AA Rampage Continues, Hernandez Torches a Week at Pensacola
By Eric Simmons ·
One Man Wrecking Crew: Brandon Compton Will Not Stop Hitting
There is no soft way to frame what Brandon Compton (AA, OF, Rank: 20) is doing at Pensacola. He arrived at Double-A after posting a pedestrian .223 batting average at Beloit and looked like a high-walk, high-strikeout bat whose power might not translate against better arms. What has followed is a demolition. Over his last 30 days, he is slashing .341/.450/.769 with 10 home runs, 26 RBI, and a 16-walk showing that confirms the patience is real. This week he went 8-for-32 with four doubles, a homer, and five RBI, bringing his Double-A season line to .343/.432/.769 across 36 games. Combined across both levels, he owns 28 home runs, 78 RBI, and an .871 OPS in 96 games. The power is not theoretical anymore.
The scouting picture on Compton centers on a 55 raw power grade paired with a 40 hit tool and real swing-and-miss risk. The strikeout load is still there: 143 punch-outs combined on the season, and a contact rate of just 57.9 percent that reflects a timing window that can be exploited by plus velocity and tight spin. But his swing rate of 40.3 percent puts him in legitimately selective territory, and when pitchers miss over the plate, he does not miss back. The walk rate at Beloit was absurd, and the Double-A walk totals confirm he has not abandoned the zone discipline just because the results are louder now. Left field is his defensive home with limited projection beyond it, so the offensive bar is steep. Right now he is clearing it by a wide margin, and a Triple-A assignment feels closer than it has at any point this season.
11 Hits, 10 RBI, Five Doubles: Cristian Hernandez Has Something to Say
Cristian Hernandez (AA, SS, Rank: 19) had a week that reframes a conversation. Across 31 plate appearances at Pensacola, he recorded 11 hits, five doubles, a home run, 10 RBI, and six walks, producing one of the system's loudest offensive lines of the week. The context matters because his last 30 days had been a grind, hitting just .230 with a 27-strikeout stretch that highlighted the aggressive contact profile's downside. At 51.3 percent swing rate with a 68.3 percent contact rate, Hernandez attacks early and often, and when he is not squaring pitches up, the strikeouts pile fast. This week, the aggression paid off in run-producing doubles and a hard extra-base hit that inflated his RBI total in a hurry.
Hernandez is a 55-athlete with a 60 speed grade and the defensive instincts to stay at shortstop, and the projection has always been built more around the glove and the legs than the bat. He has 28 stolen bases this season to go with an .256/.337/.418 slash line through 407 plate appearances at Double-A, which represents genuine improvement from his A+ campaign in 2025. The power grade sits at 45, and his 11 home runs on the year exceed what that grade would suggest, even if the home run total includes some that sneak over. The up-down projection is still the most realistic destination, but weeks like this one chip away at that ceiling. He is 22 years old at Double-A with speed, defensive versatility, and an aggressive offensive profile that at its best produces what he showed this week.
Quick Hits
- Brendan Jones (AAA, OF, Rank: 23) · earned his first Triple-A assignment after posting a .234/.342/.445 line with 12 home runs and 36 stolen bases at Double-A Pensacola. In his first five games at Jacksonville, he went 4-for-11 with two doubles and four walks across 15 plate appearances. The power grade is 40 and the profile projects to a bench role, but his 65 speed, 55 field grades, and a walk rate that never disappears make him a genuinely useful piece at any level. He had stolen 40 bases combined this season before the promotion, and the speed travels.
- Deyvison De Los Santos (AAA, 3B, Rank: 33) · mashed three home runs in just 17 plate appearances this week, driving in five runs while striking out eight times, which about summarizes the entire profile. The 60 raw power is the carrying tool, and over his last 30 days he is slashing .284/.351/.537 with five home runs in 74 Triple-A plate appearances. Combined on the season he has 16 home runs and a .472 slugging mark across 377 AAA plate appearances; the 45 hit tool and documented chase tendencies are the reason he has not forced a big-league look for longer than three games, but the power production is consistent enough that a sustained stretch of contact would change the conversation quickly.
- Max Williams (A+, OF, Rank: 36) · put together 9 hits and three home runs across 24 plate appearances at High-A Beloit, adding a double and five RBI to his week's line. For a left-handed corner bat fresh off shoulder surgery and with only 26 combined games of pro experience, those numbers are striking. He is hitting .350/.440/.600 with six home runs in 116 plate appearances across both levels this year, and his last-30-day line at the A-ball level reads .364/.451/.614. The 50 hit and 50 power grades feel conservative given this early sample, though the shoulder history and limited reps rightfully temper any aggressive projection. Still worth watching closely.
- Jonathon Long (AAA, 1B, Rank: 8) · continued his outstanding stretch with 8 hits, a triple, and seven walks in 25 plate appearances, driving in three runs without hitting a home run. Over his last 30 days he is hitting .362/.474/.550 with 17 walks in 97 Triple-A plate appearances. The 55 power grade and patient 40.6 percent swing rate define his profile: Long does not expand the zone, and pitchers pay when they miss. His combined season line stands at .287/.377/.454 with 12 home runs in 487 plate appearances. The question is whether that translates against major-league velocity once the swing length gets tested harder.
- Juan Matheus (AA, SS, Rank: 39) · went 8-for-27 with three doubles, six walks, and five RBI at Pensacola, working the count at an 80.9 percent contact rate that reflects the switch-hitter's most consistent strength. He is hitting .284/.344/.420 at Double-A through 280 plate appearances this season, with 15 stolen bases showing the 50 speed grade is a floor. The profile is steady rather than loud, a utility-track infielder whose gap in tools narrows when he makes this kind of on-base contact.
- Dylan Jasso (AA, 3B, Rank: 35) · delivered 6 hits and a homer across just 15 plate appearances, driving in seven runs in a short but productive week. His last 30 days have been the best stretch of his Double-A tenure: a .436/.478/.590 slash with an 88.4 percent contact rate and only four strikeouts in 46 plate appearances. The 50 hit and 45 power grades may both be in play right now. The season line sits at .261/.351/.392 through 211 at-bats, and this recent stretch suggests the 39.4 percent swing rate and selective approach are locking in against Double-A stuff.
- Manuel Genao (A, RHP, Rank: 27) · spun five innings of two-run ball this week, scattering four hits without walking a batter and striking out six. The season ERA sits at 3.98 through 95 innings at Jupiter, which is a respectable number for a 20-year-old still building out his arsenal. His 30-day stretch has been bumpier, a 5.50 ERA across 18 innings, so the cleaner week is welcome. The 94-96 mph sinker is his best weapon, and the command grade of 45 means outings like this one, where he avoids free passes entirely, reflect his upside. The changeup at 40 is the developmental pitch to watch as he targets a back-end starter role.
- Chase Jaworsky (A+, SS, Rank: 30) · went 4-for-11 with a homer and three RBI across 11 plate appearances. It is a small sample, but it fits a genuine trend: over his last 12 games he is hitting .342/.432/.500, his contact rate has climbed to 80 percent, and the season-long .209 average at Beloit is starting to look like a cold stretch rather than a talent statement. He is a 60 speed, 60 athleticism player with a utility projection, and if the bat catches up to that athleticism even partially, the profile gets more interesting.
- Aiva Arquette (AA, SS, Rank: 3) · returned from a lengthy injured-list absence, last playing June 26 before being shut down. In two games back at Pensacola, he went 3-for-8 with a home run and a walk in 10 plate appearances. The early returns on his swing are sharp, and his combined season line of .231/.295/.455 with eight home runs across 132 Double-A plate appearances shows the power potential that makes him the system's third-ranked prospect. Getting healthy and logging innings matters most right now.
- Dillon Lewis (AA, OF, Rank: 28) · also returned from the IL this week after last appearing June 24. In his first game back, he went 1-for-3 across three plate appearances. He owns a .241/.315/.510 line with 17 home runs in 276 Double-A plate appearances this season, which is a meaningful power showing for a player at this level. Staying on the field is the primary variable now.
- Santiago Solarte (RK, SS, Rank: 55) · continues to make noise in the DSL. He went 3-for-13 with a homer and four RBI this week, bringing his season line to .325/.437/.590 with 10 home runs and 40 stolen bases in 199 rookie-level plate appearances. The 65 raw power grade on a 17-year-old is the headliner, and the 40 stolen bases confirm the 55 speed grade is real. The 44.7 percent contact rate on a 61.4 percent swing rate is the swing-and-miss red flag to monitor as he climbs, but the production at this age is genuinely uncommon.
- Wikelman González (MLB, RHP, Rank: 60) · was claimed off waivers from the White Sox organization and optioned to Triple-A Jacksonville. His one outing in a Marlins uniform was rough, just 0.1 innings with three walks and two earned runs, so there is nothing to evaluate yet. He posted a 6.57 ERA across 24.2 innings at Charlotte before the claim. A 34 strikeout-to-15 walk ratio at the AAA level gives him something to work with, but the early Jacksonville appearance was about as bad as a debut can be on a per-inning basis.
