Jason Isringhausen auditioned for Mets assistant general manager J.P. Ricciardi at the team's Florida complex on Tuesday morning. He last pitched in the majors when he made nine appearances for the Rays in 2009. Isringhausen, 38, originally was drafted by the Mets 20 years ago and pitched in the majors with the club from 1995 through 1999. "We've got a history from Oakland, things like that," Isringhausen said, referring to his relationship with Ricciardi. "We've always been cordial friends. So I talked to my agent, my agent talked to J.P., and I just came down here and threw a little bit. All I need is a chance to throw in the spring somewhere."
