I think there's something to the notion that Rocco will need time to figure out how to use his bullpen pieces, but that shouldn't be the case with a guy like Duffey, who isn't a new piece. And as @ashbury pointed out, a clean inning is a unicorn for this pen. That trend alone doesn't give me many warm fuzzies as the season wears on, and especially as injuries start to take their inevitable toll.
