Unless Irvin or Parker are very bad, it'll be a vet or two pushed out of the way when Cavalli and Gray are back. Most likely Corbin will be moved. I think there's a chance that the first move is to DFA Rainey, figure he clears, then outright him to rochester. Perhaps Corbin is pushed to the bullpen as a multi-inning low leverage guy initially, and at some point, you'd expect Williams to be dealt.
