We have a day off after game 1 too. Even more reasons to do a purposeful bullpen game.
We could use everybody but Wheeler and Nola and all the 1-inning relievers have a day off and then Rob could also start any of the longer-use arms in game 4 anyway. There are 2 days off between games 1 and 4.
Maybe we start Ranger and he goes 6 in game 1 and 4. He certainly has earned the chance to do that, but given that he was going to be the early reliever if Nola faltered last night I am guessing both he and the manager are on the same page about using him any time they need him.
