If the Cubs can't move Chatwood and he doesn't have a place in the starting rotation because the other five are healthy and ready to go, the Cubs have eight "salaried" relievers already, plus an out-of-options Allen Webster.
Chatwood, Tyler
Cishek, Steve
Duensing, Brian
Edwards, Carl Jr.
Kintzler, Brandon
Montgomery, Mike
Morrow, Brandon
Strop, Pedro
There will have to be some creative movement if they want to bring back Chavez and add someone else even on top of that.
