Mets Ask Isringhausen to Remain in Florida By DAVID WALDSTEIN Published: March 28, 2011 PORT ST. LUCIE, Fla. � The Mets have asked the right-handed reliever Jason Isringhausen to remain in extended spring training for a week or two to increase his arm strength and reassure them that his elbow is healthy. Isringhausen, 38, had been against the idea, but he told the Mets he would consider the possibility. He has said he will not pitch in Class AAA once the season starts. The Mets have also discussed the idea of asking another right-handed reliever, Blaine Boyer, to accept a minor league assignment. He has an opt-out in his contract that would allow him to become a free agent if the Mets do not put him on the 25-man roster. Both Isringhausen and Boyer have pitched well this spring. But the Mets are particularly intrigued by Isringhausen because of his experience as an elite closer, and because he reached 92 miles per hour on their radar gun Sunday in his last outing after experiencing soreness in his elbow last week. They also see him as someone who could provide guidance and leadership to younger relievers, especially Bobby Parnell. The Mets, who are likely to open the season with 12 pitchers, including seven relievers, are trying to figure out a way to keep Manny Acosta, too. Their goal is to keep as many pitchers as possible, and they know if they put Acosta on waivers, he will almost certainly be taken by another team.
