I wouldn't mind seeing a better base stealer and defensive replacement on the bench. Zimmer is acceptable, but I feel like it's a low-cost upgrade position. Someone like Billy Hamilton maybe, or we could try to fill it internally with Samad Taylor or Steward Berroa (both of whom will be rule 5 eligible). Taylor is probably roughly MLB ready anyway, and I double we'd care about burning an option on Berroa.
Really, I'd just like to see a good reliever or two, maybe along the lines of the Cimber trade last year. I don't think we need anything dramatic. If something else falls into our lap, great.
