"It doesn't appear there is going to be room in the Mets' retooled bullpen for Jason Isringhausen.

Sources said the team "hasn't ruled anything out," but they don't expect him back.

"There probably isn't a fit for him here," another source said. "He's been talking to other teams, and we think he'll wind up elsewhere."

Isringhausen, 39, made an unexpected return to the majors — and his former team — a year ago when the right-hander showed up at spring training to get some work in to see if he could still pitch.

The Mets' new regime was impressed — and in dire need of help in the bullpen — and Isringhausen came at the bargain-basement price of $500,000. It was a salary he said he wouldn't be willing to play for again."
