The Miami Marlins were one of several teams to announce their list of non-roster invites on January 29. It’s a lengthy and loaded list, as it includes Tommy White and Robby Snelling, arguably the Marlins’ two best pitching prospects.
The prospects
The big name among the Marlins’ non-roster invites is Thomas White, a 2023 first-round pick who is arguably the best prospect in the system.
Between three levels, White struck out 145 batters over 89.2 IP. The left-hander also ranked either at the top or near it, in terms of swing-and-miss, in both the Midwest League and the Southern League.
White’s fastball is a tremendous asset. It’s a pitch that’ll sit 94-95 MPH but White can run it up to 97-98 MPH if need be, and it gets swing-and-miss. Aside from that offering, White will work with a changeup that sat in the mid-to-high-80s, plus a slider and a sweeper.
The Marlins will also bring two of their other big-name pitching prospects, Robby Snelling and Karson Milbrandt.
Snelling, acquired from the Padres in 2024, had a very good bounce-back season in 2025. The 22-year-old left-hander struck out 166 batters over 136 combined innings between Double-A and Triple-A last season. He did his finest work in Triple-A, as Snelling struck out 81 over 63.2 IP and a 33.9% Whiff% that ranked among the top-ten in the International League.
A four-pitch pitcher, opposing batters had a hard time squaring Snelling up. His 3.4% opponents’ Barrel% ranked among the best in Triple-A, as well.
Milbrandt struck out 113 over 90 Minor League innings last season, and then finished second in the Arizona Fall League in strikeouts (23) this past fall. The 21-year-old Milbrandt, who posted a 34% Whiff% in High-A last season, was a third-round pick in 2022.
Evan McKendry, Jack Ralston, Justin King, Dale Stanavich, Nigel Belgrave, Josh Ekness, and Samuel Vazquez are among the other pitchers who will be in camp.
As for the hitters, the Marlins will have several of the hitters acquired in trades over the past few years. Matthew Etzel, Andrew Pintar, and Nathan Martorella will be in camp. The Marlins also invited Dillon Lewis, Dylan Jasso, and Brendan Jones, three of the prospects acquired in the Ryan Weathers trade.
Kemp Alderman, a second-round pick from 2023, is a homegrown prospect who hit 22 home runs between Double-A and Triple-A last season.
Infielder Jacob Berry was the sixth overall pick by the Marlins in 2022. His stock has fallen considerably since he was drafted, to the point that he was left unprotected for the 2025 Rule 5 Draft. Berry slashed .261/.348/.394 with eight home runs and 37 extra-base hits for Jacksonville last year.
Other hitters who will be in camp are outfielder Fenwick Trimble, catchers Ryan Ignoffo and Bennett Hostetler, as well as infielders Jesus Bastidas and Johnny Olmstead.
Other notables
Tyler Zuber, Patrick Monteverde, and Jesus Tinoco, all of whom have worked in the Marlins’ bullpen over the past few years, will be in Miami’s camp.
Ex-National Zach Brzykcy will get a fresh start with the Marlins. Brzykcy was a strikeout machine in the Minors and induced a fair amount of chase (31.9%) at the MLB level last season. However, he walked 12 and gave up six home runs over 23 innings with the Nationals last season.
Outfielder Daniel Johnson, drafted by the Nationals in 2026, spent parts of four seasons (2020-21, 2024-25) in the Majors. Johnson is a career .196/.243/.322 hitter over 152 career plate appearances.
The Marlins also invited Brian Navarreto, who played for the big club in 2020 and 2025.
