Yeah, I think his status is more tied to the health of others than his own. If Rodon and Dallas are back and healthy, his road to a playoff roster is very small.
With Fry back and seemingly healthy, I think the bottom two pitchers on the current roster are JS and ReyLo. The other guy who might be in question is Cishek, as he is on a one year deal with an option, though I can't see them leaving him off of the playoff roster in favor of Stiever. The other option would be for them to leave off a position player for an extra pitcher, so a guy like Yolmer would probably be the pick to remove, but I can't see that.
