Since it's Valdespin, who has played both infield and outfield, it could really be just about any position player who's a DL candidate, other than Thole or Nickeas. I doubt that Valdespin would be the replacement for Davis, but he could be the guy for Cedeno, Turner, Murphy, Wright, Tejada, Nieuwenhuis, Bay, Duda, Baxter, or Hairston. Sheesh!
