Hanrahan, who had Tommy John surgery a little more than 11 months ago, will likely be ready to return in May.
With Bobby Parnell out for the remainder of the season after undergoing Tommy John surgery, the Mets could use another reliable late-inning arm in the bullpen.
After Parnell went down, Mets general manager Sandy Alderson said that the team would initially look internally in order to replace Parnell. That job so far has fallen to Jose Valverde, who was solid until his alarming blown save in Anaheim on Saturday night.
The question, is whether the Mets view the 32-year-old Hanrahan as a sure thing who can take over as closer while knocking everyone else down a peg in the bullpen.
If they do, signing him would be prudent.
However, if there are any doubts about Hanrahan’s ability to step into the role of closer and be effective, it would be better off for the Mets to continue looking internally.
Vic Black has been pitching better in Triple-A Las Vegas and should be up in short order. The Mets also have Jeff Walters and perhaps Cory Mazzoni who should be able to help out in the late innings in the coming months.
