Hudson needs to be the closer. I think Doolittle is done as a closer. Last year just took too much out of him.
Is this the last year of his contract?
I imagine Hudson is the primary closer with Doolittle perhaps getting the nod when there are a bunch of lefties coming up. Rainey is waiting in the wings as the closer of the future (with Holden Powell a couple of years away).
This is Doolittle's last year. He's an UFA at season's end.
