The offseason grew more intriguing Tuesday when Jeff Berry, the rep for J.T. Realmuto, said on MLB Network Radio that his client would not sign an extension with the Marlins and, “I think he will definitely be wearing a different uniform by the start of spring training.”

Realmuto is 27 and the game’s best overall catcher at a time when there is a dearth of quality at that position. That could make him more desirable to teams than even big free agents Bryce Harper and Manny Machado. Will the Marlins trade him with two years until free agency?

They have dangled him before, and among many pursuers were the Nationals and Braves. The emergence of Juan Soto moved Washington to eventually include Victor Robles in proposals, but not shortstop Carter Kieboom, which curtailed talks. Atlanta has more layers of well-regarded pitching prospects than any organization.

But if Realmuto is truly available, the Marlins will have many suitors, with multiple executives mentioning the Astros as an expected strong player and to a slightly lesser extent the Dodgers.

Yankees GM Brian Cashman already has said Gary Sanchez is the Yankees’ catcher next year. But if it matters, he has four years to free agency and when Miami’s influential vice president of player development and scouting Gary Denbo was running the Yankee farm system he was said to be a fan of Sanchez. Does that create the firmament for a potential deal?

Giants slowly searching for experienced GM

One reason the Giants’ GM search is going slower than, say, that of the Mets is they prefer to hire someone with prior experience, an official familiar with the search told The Post. But candidates the Giants have looked in on, such as A’s GM David Forst and Indians GM Mike Chernoff, either have or are going to sign extensions this offseason, and the Indians president of baseball operations Chris Antonetti, Brewers’ GM David Stearns and Diamondbacks GM Mike Hazen are under contracts and either don’t want to move or are not being permitted to interview elsewhere.

MLB Network’s Jon Morosi reported the Giants have interest in Dodgers GM Farhan Zaidi for a president of baseball operations role. Multiple executives have expressed belief that internal change is possible with the Dodgers having lost consecutive World Series while remaining without a title since 1988. The only seismic alteration would involve Zaidi, president of baseball operations Andrew Friedman or manager Dave Roberts, whose 2019 contract option must be decided upon by next week.

Giants president Larry Baer did not respond to a text message asking about the status of the team’s GM search.
