2026 Opening Day roster for Marlins Triple-A Jacksonville affiliate

[Ely Sussman]

One quirk of the 2026 Miami Marlins schedule is that the organization's first minor league game begins before its major league opener. The Jacksonville Jumbo Shrimp host the Rochester Red Wings this Friday at 7:05 p.m. ET, while first pitch of Opening Day in Miami will be approximately five minutes later.

The Jumbo Shrimp announced their initial 30-man active roster on Wednesday afternoon. Don't get too attached to this group, though, as Triple-A rosters tend to churn constantly throughout the course of the season.

Seven of our Fish On First Top 30 prospects have been assigned to Jacksonville as indicated in parentheses below. That's without including Maximo Acosta (FOF #15), who will likely be optioned to Triple-A once he recovers from his left oblique strain.

Pitchers (15): Garrett Acton, Bradley Blalock, Josh Ekness (FOF #27), Dax Fulton, Braxton Garrett, Cade Gibson, Ryan Gusto, William Kempner, Zach McCambley, Patrick Monteverde, Jack Ralston, Robby Snelling (FOF #3), Jake Walkinshaw, Josh White (FOF #25), Tyler Zuber

Catchers (3): Bennett Hostetler, Joe Mack (FOF #2), Brian Navarreto 

Infielders (7): Jesús Bastidas, Jacob Berry, Deyvison De Los Santos (FOF #28), Nathan Martorella, Cody Morissette, Johnny Olmstead, Jared Serna  

Outfielders (5): Kemp Alderman (FOF #10), Matthew Etzel, Daniel Johnson, Ethan O’Donnell, Andrew Pintar

7-day IL: Evan McKendry, Jesús Tinoco, Thomas White (FOF #1)

Notable prospects who finished the 2025 season with the Shrimp but didn't crack this roster include right-hander Nigel Belgrave and left-hander Dale Stanavich. Expect them to start off with Double-A Pensacola.

Pensacola's full roster will be announced next week.

I'm heading back to Jax for a few months, and frankly, catching a bunch of Shrimp games will be the highlight of the trip. They're destined for another season win total much better than the big league team, as much as I hate to state that.

I'm aiming for a few games in Jax and a few in Miami this year. Tough flying from AZ though, but at least one game will be here when they visit the DBacks.

That's a trek, for sure. I'm old, nothing else to do, so I split my year between Louisville and Jax, with a couple of Jax to Miami road trips. Cheers
