White

White allowed five runs on one hit with four walks in 2/3 of an inning on Sunday. He will go back to an impressive Triple-A statline of a 1.33 ERA, 1.00 WHIP, and a 28/15 K/BB ratio across 27 innings.

It’s the first trip to the big leagues for the 25-year-old hurler and is certainly well deserved after two years of dominating batters at the Triple-A level. In 17 appearances at Triple-A Jacksonville this season he holds a minuscule 1.33 ERA, 1.00 WHIP and a 28/15 K/BB ratio across 27 innings of work. Expect him to be used in a middle relief role initially for the Marlins.

We’re still early enough in camp that teams aren’t faced with difficult decisions just yet, so there are no surprises here. Fulton, 26, had a particularly brutal 2025 season, registering a 5.38 ERA, 1.62 WHIP and a 115/59 K/BB ratio over 103 2/3 innings between Double-A Pensacola and Triple-A Jacksonville. He’ll continue to operate as extra pitching depth for the Fish.

A phenomenal defender behind the plate, Mack projects as Miami’s catcher of the future and should enter spring training with a chance to seize the starting role. Agustín Ramírez offers a much higher offensive upside, but his omnipresent defensive challenges make him more of a long-term fit at DH.
