Earlier this year, Baseball America presented the Top 30 Marlins Prospects for 2026. Now, we’re digging even deeper to highlight prospects who just missed making the cut but still have the potential for breakout seasons or future MLB careers.

Here are the next 10 players to know in the Marlins system beyond their Top 30. You can find the complete index of players who just missed their teams’ respective lists here.

31. Kifraidy Encarnacion, LHP

Encarnacion is a long, athletic lefthander with extreme arm strength, having touched 101 mph in 2025 while flashing a plus slider. The upside is obvious, but so is the risk, as his strike-throwing was well below average after Tommy John surgery. If Miami can rein in the delivery and find even fringy command, the raw ingredients point to a much higher ceiling than his currently absurd walk rate suggests.

32. Jared Serna, SS/2B

Serna is a compact, energetic infielder with an above-average run tool and enough bat speed to have shown surprising power earlier in his career. That power disappeared in 2025 as his batted-ball angles flattened, limiting his impact despite solid zone control and usable exit velocities. If he can reintroduce loft while maintaining his contact rates, he has a chance to be more than a utility profile. He should reach Miami this season.

33. Maximo Acosta, 3B/SS

Acosta is a versatile infielder with a plus arm and enough athleticism to contribute across multiple spots. His 2025 season, which included a stint in the majors, exposed lingering issues with swing decisions and contact quality, as increased strikeouts and limited air contact capped his offensive impact. If he can recapture the improved contact rates he showed earlier in his career, he has a chance to settle into a useful big league role rather than a depth-only profile.

34. Deyvison De Los Santos, 1B

De Los Santos possesses some of the most raw power in the minors, capable of producing top-of-the-scale impact when he squares the ball. That power comes with significant swing-and-miss and chase concerns, which were exposed during a down 2025 season after a massive home run output the year prior. His path to value is narrow but clear: he has to hit enough to let the power play.

35. Jose Castro, OF

Castro is a physical corner outfielder with plus raw power who took a major step forward in 2025, setting a DSL record with 16 home runs after tightening his approach. His profile remains volatile, as the hit tool will be tested significantly against more advanced pitching. If the improved swing decisions carry stateside, he has a chance to grow into a legitimate power bat rather than a pure tools bet.

36. Nigel Belgrave, RHP

A 15th-round pick out of Maryland in 2023, Belgrave climbed through the minors quicker than most of his late-round peers, reaching Triple-A as a third-year pro in 2025. He posted a 2.51 ERA and 92 strikeouts over 68 innings, mostly in Double-A. A reliever who throws from a low three-quarters, nearly sidearm slot, Belgrave primarily leans on a plus sweeper with above-average spin that generated a near 35% miss rate. He complements it with a high-80s cutter, a low-to-mid 90s sinker and a below-average four-seamer. Belgrave is expected to reach the majors in his age-24 season in 2026.

37. Ian Lewis, OF

Viewed by evaluators as the best athlete in the Marlins’ system, Lewis delivered a long-anticipated productive season in 2025, slashing .278/.357/.431 with six home runs, 14 doubles, three triples and 32 stolen bases in 40 attempts across Low- and High-A. His 16.8% strikeout rate marked his best showing since a 43-game stint in the Florida Complex League in 2021. Lewis logged most of his defensive innings in right field but also saw time at third base and center field. An undersized switch hitter, he will need to continue proving he can impact the game as a contact-oriented bat with speed and defensive versatility to translate standout athleticism into sustained production and upside.

38. Pedro Montero, RHP

Montero impressed as a 17-year-old professional debutant in the Dominican Summer League, posting a 3.00 ERA with 44 strikeouts against 14 walks over 36 innings. A wiry 6-foot-1 right-hander, Montero has room to add strength to his frame but already features a fastball that sits 92-95 mph and touches 97 with carry through the zone, along with a sweepy slider that some evaluators project as a future plus offering.

39. Jose Paulino, RHP

Paulino returned to the DSL as an 18-year-old in 2025 after throwing 21 innings there the previous season and showed advanced stuff for his age over 38.1 innings. The 6-foot-3 righthander struck out 56 batters against 20 walks while posting a 4.70 ERA. His best present offering is a high-spin, low-80s curveball with impressive depth, and his mid-90s fastball has also shown quality characteristics. Paulino is expected to make his stateside debut in 2026.

40. Dax Fulton, LHP

Fulton is a massive lefthander with mid-to-upper-90s velocity and well-above-average extension, but his pure stuff has yet to translate into consistent results. After returning from Tommy John surgery, he struggled to throw quality strikes in 2025, and his fastball lacks the movement needed to miss bats at a high rate. The ingredients are still present, but health, command and refinement will determine whether he becomes more than a long-term upside play.
