Although it would be a risk to sign this guy, he could possibly become a real asset for the club (at the moment). Of course in the future, when our starters are back, he will be less useful. However, he could prove to be worth signing and could become a 4th or 5th starter.
Or maybe, he can go to the bullpen? I'm sure he has the stuff to do it, maybe he can boost up our bullpen. Jepsen did fine for himself last year but has only had 1 clean game so far from what I can remember. I know its too early to judge, but it is something to realize and monitor.
