Joe

Mack

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.

The 22-year-old top prospect has been heating up this summer, hitting .279/.323/.574 in July with four home runs, eight RBI, and two steals. The Marlins have said they are moving forward with Agustin Ramirez and Liam Hicks at catcher for the remainder of 2025, but neither one of them is a particularly strong defender behind the plate, which gives Mack a good chance to be the primary catcher in 2026.

Wetherholt — who was promoted to Triple-A Memphis earlier this week — headlines a senior circuit lineup that includes rising fantasy sensation Konnor Griffin, who has emerged as arguably the top prospect in the entire dynasty landscape during his professional debut. It also features Dodgers burgeoning sluggers Zyhir Hope and Josue De Paula in addition to Brewers phenom Jesús Made, who has cemented his status as a top-10 dynasty prospect in the game. Here’s the full lineup: Wetherholt (DH), Griffin (SS), Owen Caissie (RF), Charlie Condon (1B), Hope (CF), Made (2B), De Paula (LF), LuJames Groover (3B), Joe Mack (C) and JR Ritchie (P).

It’s worth noting that rookie backstop Agustín Ramírez went 2-for-4 in this one and is now hitting .283 through 14 games to open his big-league career. Meanwhile, Mervis’ latest hitless performance leaves him at .191 through 29 contests. The Marlins have top prospect Joe Mack, who is a phenomenal defender behind the plate, pushing to reach the big leagues soon. The logical decision would be to shift Ramírez to a full-time DH role, which would likely bump Mervis from the roster altogether.
