Miami Marlins’ catcher J.T. Realmuto is not going to sign an extension with the Marlins, so he will likely be tied to every team in the market for an upgrade behind the plate this winter.
Realmuto’s agent, Jeff Berry, told MLB Network Radio in an interview on Tuesday that the 27-year-old catcher, (who’s under team control through 2020 and coming off a .277/.340/.484, 30 double, 21 home run, 4.8 fWAR 2018 campaign), has, “... informed the Marlins’ ownership, he’s informed their front office, he’s not going to sign an extension in Miami.
