It has been great to see Folty start to click and really pitch well along with Fried. Soroka seems to be struggling his last few starts, so will be interesting to see if he can turn it around to finish the season.
I'm sure Snitker will want to mix up lefties with righties unless an opponent is just atrocious against either side, but my gut says he is really going to value the more experienced pitchers, so would not be surprised to see Keuchel, Folty, and Teheran with Soroka as the 4th unless he continues to struggle or Fried just continues to dominate. Then you have either Soroka or Fried off the bench as a mid reliever for the first guy that has any hint of struggles early on.
Going to be a tough choice for the captain to make given how all of them are now pitching. I will say Soroka has been lights out on the road all year compared to the rest of the staff which is another reason Snit will likely give him the nod unless his struggles continue.
