“The Mets made what they perceived as a last-ditch effort to sign Pete Alonso by offering him a three-year contract in the $68 million-$70 million range, and when that was rejected, began their pivot away from their slugging first baseman, The Post has learned.”

The Mets, according to sources, are of the belief Alonso will sign elsewhere. The Post’s Joel Sherman reported on Thursday that Alonso declined a three-year offer from the team that would have paid in the $68 to $70 million range.

League sources confirmed a report from SiriusXM analyst Jim Duquette, a former New York Mets general manager, saying Alonso’s camp offered the Mets a three-year deal with opt-outs. Duquette reported the offer was only available to the Mets. The former exec added that Alonso’s agent Scott Boras declined to comment.
