The Miami Marlins have long been known for their ability to develop pitching talent, and their current farm system reflects that strength. However, in recent years, the organization has placed a greater emphasis on improving its offensive depth, acquiring promising bats through both the draft and trades. As the Marlins continue to build for the future, their top prospects provide a strong foundation for the next wave of talent set to impact the big-league roster in the coming seasons.

At the forefront of the Marlins’ system is Thomas White, a hard-throwing left-hander with the potential to be a front-line starter. Joining him in the pitching ranks is Noble Meyer, another high-upside arm, along with Robby Snelling, who was acquired in a trade with the Padres. On the offensive side, Agustín Ramírez brings intriguing power at the catcher position, while infielders Starlyn Caba and Deyvison De Los Santos provide both upside and depth. Jakob Marsee and Joe Mack add further intrigue with their blend of contact skills and defensive abilities.

With a mix of high-ceiling arms and power bats, the Marlins’ farm system is shaping up to complement their already talented young core at the major league level. Whether these prospects become key contributors in Miami or serve as trade assets to bolster the big-league roster, their development will be crucial in determining the franchise’s trajectory. Let’s take a closer look at the Top 10 Marlins Prospects for 2025 and see who could be the next standout in Miami.

1. Thomas White (LHP, Age: 20)

Thomas White, Miami’s first-round pick in 2023 (35th overall), had a breakout year in 2024, earning the Marlins’ Minor League Pitcher of the Year honors. At High-A Beloit, he pitched 96 innings across 21 starts, striking out 120 batters and walking 38. His fastball sits in the mid to high 90s, complemented by a plus changeup and a curveball that he locates effectively. White is expected to begin the 2025 season in Double-A, with the potential to rise quickly through the ranks. ​

2. Noble Meyer (RHP, Age: 19)

Selected 10th overall in the 2023 draft, Noble Meyer spent 2024 between Single-A Jupiter and High-A Beloit. In 19 games (18 starts), he posted an impressive 10.3 K/9 rate but issued 55 walks over 74 innings, indicating room for improvement in his control. Meyer was named to the 2024 Futures Game, where he pitched one inning for the National League, striking out two and walking one. A promotion to Double-A in 2025 will be a significant test for his development.​

3. Agustín Ramírez (C/1B, Age: 23)

Acquired as the main piece in the Jazz Chisholm trade, Agustín Ramírez is one of the best offensive catchers in Minor League Baseball. After an initial struggle following his promotion to Triple-A, he found his footing with the Jacksonville Jumbo Shrimp, ending the season with a career-high 25 home runs. The organization believes there is still untapped power potential in his bat, making him a prospect to watch closely. ​

4. Robby Snelling (LHP, Age: 21)

Robby Snelling joined the Marlins organization via trade, coming over from the Padres in exchange for Tanner Scott. The 21-year-old southpaw features a fastball-slider combo but experienced a dip in effectiveness in 2024, yielding three more hits per nine innings than the previous year. He’s also developing a changeup, which has shown promise. A bounce-back year could revitalize his prospect status. ​

5. Starlyn Caba (SS, Age: 19)

Acquired from the Phillies, Starlyn Caba is a great athlete with the potential to stick at shortstop. He exhibits excellent plate discipline, walking more than he strikes out, and possesses 70-grade speed. The development of his power will determine his ultimate ceiling, but his defensive skills and on-base abilities make him an exciting prospect.

6. Deyvison De Los Santos (1B, Age: 21)

Deyvison De Los Santos came to the Marlins alongside Andrew Pintar in a trade with the Diamondbacks for A.J. Puk.His raw power and exit velocity rank among the best in the minors, thanks to his bat speed and strength. After the trade, he hit 12 of his 40 home runs for the Jacksonville Jumbo Shrimp, leading the minors in homers.

7. Jakob Marsee (OF, Age: 23)

Jakob Marsee is an outfielder who reached Triple-A in 2024. Known for his solid contact skills and defensive versatility, Marsee could provide depth to the Marlins’ outfield in the near future. ​

8. Graham Pauley (3B, Age: 24)

Graham Pauley is a third baseman who reached Triple-A in 2024. His offensive capabilities and defensive reliability make him a prospect to watch as he nears MLB readiness. ​

9. Joe Mack (C, Age: 22)

After struggling with off-speed pitches earlier in his career, Joe Mack adjusted his approach to attack early-count fastballs, resulting in 24 home runs in 2024, ranking fifth among minor league catchers. His improved offensive performance has elevated his prospect status within the organization. ​

10. Echedry Vargas (SS, Age: 19)

Echedry Vargas is a shortstop who played at Single-A in 2024. Known for his defensive skills and developing bat, Vargas has the potential to rise through the ranks with continued improvement. ​
