The Mets are leaving the light on for Yoenis Cespedes if he wants to return to Citi Field on a short-term deal and leave tens of millions of dollars from another team on the table.

While even the Mets think that is unlikely, there’s no harm in hoping Cespedes enjoyed his time in Flushing so much that he will pass on a reported five-year, $90-million offer from the Baltimore Orioles — or whatever more lucrative deal his agents can scare up with about a month to go before pitchers and catchers report.

Cespedes said during the season that he wants a six- year deal. It appears as if he’s more likely to get it than accept a pact of one to three years from the Mets.

But the offseason goes on, and on Friday, that meant agreeing to contracts with five arbitration-eligible players. The biggest name was Matt Harvey, who agreed to a contract worth $4.325 million for 2016. Harvey made $614,125 in 2015.

The Mets also agreed to terms with Addison Reed ($5.3 million), Ruben Tejada ($3 million), Carlos Torres ($1.05 million) and Josh Edgin ($625,000).

The Mets were unable to come to terms with their four other arbitration-eligibles (Lucas Duda, Neil Walker, Jeurys Familia and the suspended Jenrry Mejia).

Unless agreements are reached, those players will have their 2016 salaries determined by an arbitrator, who will pick either the club’s offer or the player’s request after a hearing.

Friday was the deadline for figures to be exchanged in advance of the hearings.

The Mets also signed catcher Nevin Ashley, 31, to a minor-league contract. Ashley appeared in 12 games for the Brewers last season and went 2-for-20.

Yankees sign pair

The Yankees signed two of their six arbitration-eligible players. Michael Pineda agreed to a $4.3-million contract and Dustin Ackley signed for $3.2 million.

Aroldis Chapman, Nathan Eovaldi, Didi Gregorius and Ivan Nova were unable to reach agreements and will continue on the arbitration road.

The Yankees also claimed outfielder Lane Adams off waivers from Kansas City and designated infielder Ronald Torreyes for assignment. Adams, 26, had three big-league at-bats without a hit for the Royals in 2014. The Yankees had just acquired Torreyes from the Dodgers on Tuesday.
