The source said Wright is less than thrilled with the length of contract and amount of guaranteed money the Mets have offered. It could set up a game of chicken between Mets brass and Wright’s agents, Sam and Seth Levinson, heading to the winter meetings, which begin in two weeks in Nashville, Tenn.

Wright, who turns 30 next month, is believed to be seeking a deal of at least seven years and $125 million that would give him the largest contract for a position player in franchise history.

Wright’s agents also could push for the Mets to tear up the $16 million option they recently exercised on the third baseman for 2013 and add a small amount — say $500,000 (making Wright’s new salary $16.5 million) — and allowing the sides to frame a new deal as including next season and pushing it beyond the $137.5 million contract Johan Santana received before the 2008 season.

But the two sides remain at a stalemate.

“Part of it is [COO] Jeff Wilpon tries to win every negotiation, he doesn’t go for the middle ground,” said a person familiar with the club’s negotiating tactics.

Wright has said he will not negotiate with the Mets beyond spring training, putting him in position to hit the open market next offseason if a new deal can’t be struck.
