Yoenis Cespedes has the joy of six on his mind.

The Mets outfielder, who can become a free agent after this season, says he wants a new contract that will last at least six years.

“I’m not thinking about contract negotiations, but I do know that I will be looking for a contract that is six years or more,” Cespedes told ESPN Deportes. “It has to be six years or more.”

The Mets and Cespedes recently modified a clause in the player’s contract that said he had to be released five days after the World Series. The two sides are now allowed to negotiate throughout the free-agent signing period.
