Marlins Promote Joe Mack to Debut Behind the Plate
The Miami Marlins will promote catching prospect Joe Mack from Triple-A Jacksonville to the majors before tomorrow’s game against the Phillies, optioning Agustin Ramirez to clear a roster spot. Mack, a 2021 first-round-worthy prospect, is praised for elite defense (framing, blocking, throwing) and has posted a solid minor-league line (.249/.334/.444 with 21 HR in 515 PA at Jacksonville) with improved plate discipline this season. The move is aimed at upgrading Miami’s defense behind the plate and could yield an offensive bonus, with roster and service-time ROY incentives considerations looming.
