I think it was either Pena or Hairston, and Hairston was picked because of his experience and power. Myself, I would have preferred Pena, but I'm biased towards youth. I also like Pena batting left handed, and for his additional range in the middle, and for what I think, more speed on the bases. They are both prone to errors at the worst possible times.
SoCal, if you and Hugh don't mind a little sarcasm, 3 catchers are necessary because we may need Posada's bat.
