Since president of baseball operations Peter Bendix took over the Marlins, his emphasis has been on the organization’s ability to build up a farm system capable of helping to achieve sustainable success at the Major League level.
His vision is starting to bear fruit, as Miami boasts five Top 100 prospects in MLB Pipeline’s preseason rankings.
Left-handers Thomas White (No. 17 overall) and Robby Snelling (No. 39), outfielder Owen Caissie (No. 42), shortstop Aiva Arquette (No. 47) and catcher Joe Mack (No. 62) give the Marlins five Top 100 prospects for the first time since 2022, when they had six.
The southpaw duo of White and Snelling, both of whom ended the 2025 season at Triple-A Jacksonville, are poised to debut in the Major Leagues this season. Although neither is on the 40-man roster, the trade of Miami’s lone lefty starter, Ryan Weathers, opens up a path should the Marlins continue dealing and force the issue.

White posted a combined 2.31 ERA and a 14.6 K/9 rate at three levels in 2025 – his second full professional season – as a 20-year-old. That type of dominance led to him being ranked by MLB Pipeline as the top lefty prospect in baseball. He also is the first Top 20 overall prospect for the Marlins since righty Eury Pérez in 2023.
Snelling, who turned 22 in December, was named the organization’s Pitcher of the Year and comes in as the fifth-best southpaw prospect. After 14 starts at Double-A Pensacola, he improved across the board in 11 starts at Jacksonville with a 1.27 ERA, a 0.99 WHIP and an 11.5 K/9 rate.
Caissie, who was the centerpiece of the return in the Edward Cabrera trade, is the newcomer. He debuted in mid-August for the Cubs, appearing in 12 games and receiving 27 plate appearances down the stretch for a postseason-bound club. Caissie sustained a concussion in September that limited his playing time.
The 23-year-old, ranked as MLB Pipeline’s eighth-best outfielder, will enter big league camp with a shot at winning the club’s right field job. Should Caissie do so, he will join a starting outfield that will consist of All-Star and Gold Glove nominee Kyle Stowers in left and Jakob Marsee in center.

The Marlins, who selected Arquette seventh overall last summer in the MLB Draft, challenged him from the get-go by sending him to High-A Beloit to begin his professional career. The now 22-year-old Arquette slashed .242/.350/.323 in 27 games for the Sky Carp, who advanced to the Midwest League Western Division final.
Arquette, considered an advanced bat after a stellar season at Oregon State (1.115 OPS), should continue being tested by the organization in 2026. If Arquette responds, he will be on the fast track.
Mack, who turned 23 in December, ranks as the seventh-best catching prospect. He spent nearly his entire 2025 season with Jacksonville, where he slugged 18 homers with 53 RBIs in 99 games. Arguably more important, the 2024 Minor League Gold Glove winner managed a Triple-A championship-winning pitching staff that included White and Snelling.
Added to the 40-man roster this winter, Mack will compete with second-year players Agustín Ramírez and Liam Hicks for an Opening Day spot. Miami is going to give Ramírez an adequate amount of time to show improvement behind the plate, but if there isn’t any, it’ll open the door for Mack.
