Hmm. If Britton's guess is right, maybe they want to use EdRo in the same way they're using Price, and think his stuff will play up better than Porcello's or Fister's in a one time through the order situation? If they do this, though, I think they may need to split up Sale and Pomeranz to give Price, EdRo, Reed and Kimbrel the best chance at not being overused, but somehow still sharing the bulk of the bullpen workload. Maybe Sale, Porcello (yikes, but he should start on the road if anywhere), Pomeranz, Fister. You hope Sale goes 7 innings with a lead, and Reed and Kimbrel finish it off. Then you hope Porcello can go 3 or 4 innings and give up just 1 or 2 runs, followed by EdRo and/or Price for a couple each. That gets you to the back end pretty nicely if you have a lead or are in a close game. Then everyone resets with an off day. Pomeranz goes at home in game 3, and you can follow him with really anyone - so Price and EdRo again for an inning, then Reed and Kimbrel. Game 4, if necessary and you have there 2-1 lead, you beg God for good Fister, and pull him for basically the same deal as the day before, hoping to be close after 3-5 innings. If you're down 2-1, I think Chris Sale gets the ball and everyone is on deck except Pomeranz, who'd get the ball in game 5.
I'm nervous.
