It’s the physical. Again.

The New York Mets, like the San Francisco Giants earlier in the week, have raised concerns about Carlos Correa’s surgically repaired lower right leg, potentially jeopardizing their 12-year, $315 million agreement with the star shortstop, according to people briefed on the matter who were not authorized to speak publicly.

The parties could agree to a restructured contract if the Mets continue to express reservations about the long-term stability of Correa’s leg. It might be difficult for the Mets to back out of the agreement entirely after their owner, Steve Cohen, went on record talking about the deal. It also might be difficult for Correa to re-enter the free-agent market and land a comparable contract after two clubs identified the same issue in their physical examinations of him.

The new developments are the latest twist in a saga that shocked the baseball world when Correa and his agent, Scott Boras, pivoted Wednesday from their original 13-year, $350 million agreement with the Giants to strike a separate deal with the Mets.

Cohen confirmed his apparent coup to the New York Post, saying, “We needed one more thing, and this is it.” Major League Baseball warns teams not to comment publicly on pending agreements, noting such remarks might persuade an arbitrator to side with the player in a grievance, a former executive said.
