I had more time to think about it and I think you really only need to make one move, and it's pushing Soroka to next Friday. I'd still cap him and Fried but you only need to make one move if you want Soroka and Keuchel for game 1 and 2 of the NLDS and it's this move.
The veterans can pitch as much as they like (well, maybe I'd cap Keuchel as well in that final game). The young guys like Wilson and Wright probably can't make a full start. So, what I'd do for that Wednesday that Soroka originally is scheduled in but will probably not pitch in (at least imo) is have one of the above "start" a technical bullpen game and go one time through before switching to the other.
Then I might have Fried follow Folty on that next Saturday for 2-3 innings as a tune up.
For Kansas City, I'd get guys like Riley and Hech in there both games.
