Jason Isringhausen is currently unavailable for at least the next several days because of a herniated disk in his back, but the 38-year-old reliever told Adam Rubin of ESPN New York that he plans to pitch in 2012.
Isringhausen managed only a minor-league contract offer from the Mets after missing all of 2010 following Tommy John elbow surgery, but has avoided arm problems all season while throwing 47 innings with a 4.05 ERA and 44/24 K/BB ratio.
His raw stuff is diminished from his peak as closer for the A’s and Cardinals, but Isringhausen’s fastball has averaged 90.6 miles per hour and he’s held opponents to a .206 batting average.
He’s even saved seven games for the Mets to reach 300 saves for his career. He’ll be a free agent after the season and it’s unlikely that any teams–the Mets included–will view him as a closer option, but Isringhausen should be able to secure a one-year deal for a setup gig.
