Scouting Report
Drafted by the Marlins in 2021 (Comp Round A, $2.5M signing bonus)
October 2025 update: There was an extraordinary uptick in Mack's game power from 2023 to 2024, largely the byproduct of mechanical changes (higher hand position and a narrower base). He carried that over into 2025 en route to cementing his status as one of baseball's premier catching prospects.
Leaner than the prototypical catcher, Mack still has solid blocking ability. He is nothing short of elite at controlling the running game with a lightning-quick release and consistently accurate throws, even when he's off balance. He caught one-third of would-be base-stealers in 2025.
Mack is eligible to be taken in the upcoming Rule 5 draft as things currently stand. The most obvious transaction of the 2025-26 Marlins offseason will be protecting the 22-year-old by selecting him to the 40-man roster in November.
