Regarding arrieta...just skip him. He can throw whatever simulated game he wants, but between his innings count, not letting Pittsburgh see him, and wanting Pittsburgh to win a lot of games down the stretch, I just don't see the benefits in letting him pitch. Don't throw him off his routine, or off the schedule for him to go on 10/7. If you're worried about the bullpen, let him start and pull him after 3 or something. But at this point, we're flying somewhere for that one game playoff no matter what happens. Let's do what it takes to give ourself the best chance of winning that game.
