Well, ESPN names two players, one just called up, the other who is a strong possiblility, and neither is Phiilip Huges. Since it is so early, I don't think Torre wants t bring him up right now.
That being said, the Yanks brought Robinson Cano up early and it did wonders. However, Cano wasn't a top prospect, nor was he a pitcher. They'll probably bring up a vet before Hughes.
