7:23pm: While the Mets are indeed looking for a late-inning reliever, and could give out a MLB deal to get one, the club is unlikely to land Rodney, a source tells Marc Carig of Newsday (via Twitter).
4:44pm: Though the Mets recently announced the signing of Kyle Farnsworth to a minor league deal, the team still has some money allotted for a "closer type" reliever, reports ESPNNewYork.com's Adam Rubin, citing a source that is not affiliated with the club.
Fernando Rodney is believed to be New York's top target, but Rubin's source wouldn't rule out Kevin Gregg, Joel Hanrahan or Ryan Madson either. Other relievers on the market that come with closer experience include Carlos Marmol, Andrew Bailey and Brandon Lyon, though Lyon spent last season with the Mets with less than favorable results (4.98 ERA in 34 1/3 innings). Those next three names are just my speculation, not names that were mentioned by Rubin or his source.
Rubin writes that incumbent closer Bobby Parnell is confident that he will be healthy following surgery to repair a herniated disk in his neck. However, as Rubin points out, the Mets have little in terms of a fallback plan should Parnell go down with another injury. Hard-throwing Vic Black projects to be next in line for the closer's throne, and he has a total of 17 big league innings under his belt.
They have Parnell closing already they just need a vet or two as insurance in case Parnell isn’t ready to come back right away to start the season as the closer.
These 3 seem like the likely choices at this point to possibly get picked up by the Mets now.
