I have to drop one of these players between putz or Gallardo.Can you help?

Drop Yovani. Putz will come back from the injured rib and go back to being a closer. Yovani is decent but by the time he's back, you might 15 or 20 starts out of him? And he won't win all of them. Putz comes back, he'll still get you 30 saves.
