Does this really surprise anyone, though? Pedroia is arguably the team's best player and the Red Sox are fighting for third place right now. They weren't going to throw Pedroia out there in September to try and rack in a few more wins in a season that has been an uphill climb since the getgo. It just isn't worth risking more injury to one of the best second basemen in baseball.
So, sure, this is "news" but it's news like, "Yuniesky Betancourt had a bad season" news -- you saw it coming from a mile away.
