It's hard for me to see why Chase Anderson shouldn't keep a spot in this rotation regardless of what else they do. Davies, Woodruff, and Gio are certainly locks to keep starting at the moment, so you have 2 spots between Anderson, Nelson and Chacin. Peralta just isn't going to win the numbers game and probably heads down to stay stretched out. Chacin hasn't had a great season, but he's got leash after last year. I wouldn't be opposed to a 6 man rotation, or even Nelson in the pen. But I really don't want to see Chase go back to the pen.
