Hanrahan, 32, tossed just 7.1 innings for the Red Sox in 2013 before undergoing the procedure.
Hanrahan was very productive for the Pirates between 2010 and 2012, posting ERA’s of 3.82, 1.63, and 2.72 respectively during those seasons.
His average fastball velocity peaked at 97.1 MPH during the 2011 season, and was averaging just a tick below that – 96.6 MPH – in 2013.
According to Jerry Crasnick of ESPN, the Mets, Yankees, Angels, and Rangers are among the teams who may have interest in signing Hanrahan.
The Mets bullpen was viewed as being in disarray a week ago. Over its last five games, though, the members of the bullpen have combined to hold the opposition scoreless.
Part of that bullpen success is a return to the mean, some of it has to do with Kyle Farnsworth‘s returning velocity, and some has to do with luck.
With Bobby Parnell out for the season after having Tommy John surgery, it wouldn’t be the least bit surprising if the Mets made a play for Hanrahan.
However, Sandy Alderson noted a few days ago that the club would first look internally before exploring any potential external fixes for the bullpen.
It’s unknown how much money Hanrahan is seeking, but that will obviously play into this. What will also play into it is the success of Jose Valverde over the next week or so. If Valverde continues to lock down the opposition in the ninth inning, the Mets may deem Hanrahan an unnecessary option.
