ALCS
Both the Tigers and Yankees had to use their aces in Game 5, with Detroit in a bit better shape because they had an off day between series. So in theory Justin Verlander should be able to pitch Game 3 and Game 7. That's probably not the case for New York, because Sabathia would have to pitch Game 3 on just three days' rest.
NLCS
The Giants will try to win their first home game of the playoffs; usually a club that goes 0-for-the series at home doesn't advance, especially in San Francisco's case, as they had to win three straight on the road to pull off the Division Series victory.
