J.T. Realmuto has no desire to remain with the Miami Marlins and will "definitely be wearing a different uniform by the start of spring training," according to his agent.

"J.T. has informed the Marlins' ownership, he's informed their front office, he's not going to sign an extension in Miami," agent Jeff Berry told MLB Network Radio. "It makes sense, when you have one of the more valuable trade assets in baseball, to move him. Period."

Realmuto is under team control for two more seasons -- though he is eligible for arbitration in both 2019 and 2020 -- before he becomes an unrestricted free agent in 2021.
