I'll agree with you Sonick, that they're not hitting well, but I will disagree that "not hitting well" is the sox biggest problem right now.
You cannot, under any circumstances with a 25 man roster, go to your bullpen 3 games in a row before the 5th inning. Absolutely not. I guarantee you in the regular season, Francona leaves Wake out there to pitch 2 more because during the regular season you don't have to win 4 out of 7. You have to win 90 out of 162 and the spacing is different. These are must win circumstances and your starting pitching has to go deep - and they're not. Even when the bats turned it around in the 6th, it was too late, because your starting pitching has failed you and your bullpen is exhausted.
If Beckett experiences pain or can't go deep tomorrow, you're toast.
