The New York Mets remain optimistic that they can re-sign Yoenis Cespedes, but the growing sense is that the slugger will receive a five-year offer on the open market.

Cespedes opted out of his contract with the Mets earlier this month to seek a longer deal.

The Mets would prefer to sign Cespedes to a four-year contract worth north of $100 million, according to a source.

The San Francisco Giants, Los Angeles Dodgers and Washington Nationals have been mentioned as suitors for Cespedes.
