I don't think starters innings pitched is an issue. Sure, they could chill on the full counts, but as others have noted, it's becoming the norm around the league. The issue is non-existant timely hitting, defensive blunders, baserunning ineptitude, and they really need luck to start getting on their side as well.
Sox are running themselves out of ballgames and aren't taking advantage of the gifts being given to them...the walks tonight and the 4 unearned runs against the Angels the other night as examples.
