The Sox are waiting it out. They want to do this without MDC or Masterson, and the deadline isn't until 4 pm tomorrow, so expect them to 11th hour it.
Couple of things. I don't want them to, or think they will, go for MDC unless they can trade for a replacement. He's, despite yesterday, shown his value, and you can't trade away a reliable BP arm when you are in GFIN mode. Masterson will be a bitter pill to swallow, but I can accept it because I think Ortiz is more hurt than has been reported. He's looked good because he's hitting the ball, but he just isn't the same. Not Papi good. Do this now, move Manny to DH, and get Ortiz surgery yesterday. It's supposed to be a 4-6 week recovery period, so there's even time for a hiccup to get him back by October. With Dye swinging a hot stick, our good staff, the 8 game lead, and the soft schedule (~.480 Opponent W% from here on out) I think they can manage to bring it home without him.
What I think they can't recover from is Ortiz getting hurt on Aug 1 with no replacement. I don't think WMP can approximate what a good Dye will bring.
