You could be really unconventional and go to a 6-man rotation. And use one a long relief as needed. The current rotation right now is pitching their socks off with a few hiccups here and there.
in today's Trib he was quoted that when Lilly came back, the two names that came to mind were Zambrano and Wells.
So I am going to guess Wells.
I am NOT in favor of this, BTW.
