Josh Beckett Tells Us What We All Thought Last Fall

Remember Beckett getting shelled in the ALCS followed by the press conference where everybody said he was fine? Nobody believed them then and now we find we were right all along. From the ProJo:

Beckett explained yesterday afternoon that his problem in the postseason was the
lack of explosiveness with all of his pitches due to the strained oblique.
"I
wasn't in excruciating pain or anything like that," he said. "It wasn't the most
comfortable thing I had ever done."

So why was he on the mound at all?
