He will be a little less effective than ordinarily, especially deep into the game. But he's also a total stud.
My best guess is to keep him where he is, but it really, totally depends on how good your top 2-3 rested relievers are. If you've got 3 stud rested relievers I'd drop his count, and if game 6 goes 18 innings and your pen is slagged I'd lengthen his count.
