J.T. Realmuto has informed the Marlins that he will not sign an extension with the them, his agent Jeff Berry told MLB Network Radio on Tuesday. Miami has two more years of control over the 27-year-old at the bargain price of $6.1 MM before he hits free agency, so the agent cannot guarantee the backstop won’t be in a Marlins uniform next season. However, Berry reasoned similarly to how I did when projecting the 2019 payroll: if the player won’t re-sign, then the team should deal him now while he’s at peak value and health so they can get maximum return for him.
