4.) Backup catcher
J.T. Realmuto all but solidified himself as the Marlins starting catcher last year, but the backup catcher spot was a revolving door of mediocrity. Jeff Mathis, Tomas Telis, Jarrod Saltalamacchia and Jhonatan Solano handled the duties last year, but none of them proved enough to make the return, while the aforementioned Jarrod Saltalamacchia was waived. The catcher market isn’t great, but someone like a Geovany Soto or a Michael McKenry would provide a respectable backup option to give J.T. Realmuto time off.
