The New York Mets and star shortstop Carlos Correa aren’t on the same page in contract negotiations.

The Mets have become “very frustrated” with the process over the last few days and are considering walking away, a source told Andy Martino of SNY.

The two sides reached a 12-year, $315-million agreement on Dec. 21, but the pact was never finalized because of concerns flagged during the medical about an old ankle injury.
