If Murph just wants a lefty to force Counsell to sit Busch and wasn't trying to go multiple, I think you just put Koenig in there and then run Miz or Patrick in some order.
Especially since they've really only done damage in the first inning (I'm not going to count Gasser), I think we need a good start for once - that's one reason I'd rather not start Miz because we could find ourself in exactly the same situation if he's not finding the plate.
At the end of the day though, there's no starter going here, so it's just a matter of getting 27 outs without them scoring more runs than we do. I don't care about the order or how many pitchers it takes. The A team needs to execute, and if they do, I like our chances.
