I think based on what he's accomplished thus far, it'll be another 2-3 blown saves before I really start worrying about whether or not he has the "stuff" to close. What I AM worried about is whether he's hurt or not. Look at his velocity in the last few games...few, if any of his pitches end up over 90. He's just got the low slider, which is a great pitch if you have something else to go with it, which Demp has had? Ryan seems like a great guy and it wouldn't surprise me if he's playing hurt thinking he needs to push through it while the team is stinking so badly. Didn't Borowski end up being a victim of the "hidden injury?" It may end up Demp needs time off soon, in which case it might be timely to try out Kerry Wood: Closer to give him some polish before the trade deadline.
