Storen got out of the 8th. he's just not used to sitting through the bottom of the 8th and coming back out in the 9th after gearing up for a hi-lev spot the prior inning.
As I posted in the GDT, if you want to get on Davey, get on him for burning out Soriano in the ChiSox series so he was unavailable for the 9th. We are in stronger position if we don't deplete the ammo before a divisional series against the team that is likely to be our main competition for 1st. Soriano available, then there is no harm bringing in Storen when Clipp gets wild and can't finish the 8th.
