I’m not sure if Mike or Ben has anything planned for an overnight. But Rasner will jump in the rotation for the disabled Phil Hughes on Sunday. As I said in the game thread, this is the second time in a year — almost to the day — that I’ve been set to see Hughes pitch on a Sunday, only to have him get injured. And yes, Rasner was his replacement last time, too.
So I guess that solves the whole “does he get sent down” question. You have to figure he’ll make at least two rehab starts before returning.
