I would look to add to the bullpen with whatever budget is left over after finding an infielder and a catcher.
They have 5 spots taken by relievers without options: Hoffman, Nance, Banda, Funderburk and Gomez. I would move Ober to the bullpen because I think he’s a better pitcher than what you can get for $6M in free agency. That leaves 2 spots if you plan on optioning everyone with options (Sands, Morris, Adams, Festa). Leaving a spot open to move players with options up and down is a good idea. That means I would spend whatever I had left on the best arm I could find. I think that means a $6M pitcher who will keep Adams in AAA. That’s someone like Paul Blackburn, Kenley Jansen, Mark Leiter, etc.
