Despite spending his entire career with the mostly less than respectable (pre-2012) Nationals and Pirates, Joel Hanrahan has pretty respectable numbers. It's unclear how the Red Sox will be handling the Andrew Bailey/Joel Hanrahan closer balancing act, though the online depth chart does designate Hanrahan as the ninth inning guy.
Hanrahan spent some time at Fenway Park this week, and seemed willing and ready to share time with Bailey: "...we'll get along great. All you can do is root for each other to have success and pull for the team. That's what we're going to do, I believe. He was in a tough spot. Any time you injure your hand in spring training, that's not fun. Especially coming over to a new team. I'm sure he's got to prove this year." (quote via Boston.com's Extra Bases blog).
Hanrahan also commented on the increased media presence at Fenway as opposed to his old home with the Pittsburgh Pirates, conceded that he was bound to say some stupid things, and reassured everyone that he would just roll with the punches.
Overall, Hanrahan seems like a good fit for the Red Sox. The projections that James and his team did were calculated under the assumption that Hanrahan would be the closer for the Pirates, so it's possible that he'll see more save opportunities - though it's nice to know that (barring a trade), the Red Sox will have two established closers waiting in the bullpen.
