It's time to send Chapman to AAA
Either way, he's an arm you can't go to in the bullpen right now and the inability of Dusty to use him will just tax the working arms in the pen that much more.
The Reds don't have another off-day for ages. You can't pitch shorthanded out of the bullpen for that time period. Let Chapman work himself out in the minors and bring an arm that CAN retire major league hitters up right now.
