4. The Clay rules
The Red Sox are being very careful about how many innings Clay Buchholz (who will start on Wednesday for the first time since his no-hitter) pitches, and it remains unclear what his role will be with the team in October. Will the team loosen the inning-count rules in the postseason and turn him into a possible stopper in the bullpen (think K-Rod with the Angels in 2003)? Or will he be only available for extremely limited duty?
