"They are really trying to move Isringhausen, and also Byrdak and K-Rod (before the July 31 non-waiver trade deadline)," one of the sources said. "Those guys have pitched well, and they could help somebody."
With many contending teams looking for bullpen help, Alderson hopes he can parlay his veteran pitchers into decent minor leaguers - high-end prospects is probably a stretch - or at least salary relief.
Both Isringhausen and Byrdak have proven effective in their roles this season, and neither is under contract for 2012. It seems doubtful that either could bring a significant return in prospects, but the Mets will shop them aggressively, sources say, and see what market develops.
