MVP is probably right in that Pablow has until June. That is, of course, if he starts to produce more regularly.
I don't see him failing miserably until June, either. If he sucks hard for the next couple of weeks the Sox will make a move.
I have said this before, I think he has shown signs of life at the plate. Other than the misadventure of him batting from the right, he mostly "looks" like his swatting old self at the plate. He seems to make hard contact frequently, just not for hits.
His range, especially to the left, is disappointing if not unexpected. He is 3 years older that when he played decently in SF. His footwork appears decent but he makes many wild throws where he releases the ball early. That can be fixed. He is known to be a "hard worker" so I see no reason why he can not fix this aspect of his defense.
Of course the Sox need to suss him out thoroughly before replacing him.
I do like Hernandez, though.
Just a dumb signing that continues to look bad.
