Maybe you take your chances with Monty on Friday to see how much pen they need. After the game, they make a roster move/Iowa shuttle to bring back a reliever for Saturday. Couple that with an addition pitcher for the two Saturday games (26th man) and there should be plenty of arms available. Have Lester start Game 1 on Saturday. If he can give you a decent start, there should be plenty of arms for the DH. I think the bigger problem will be Sunday. They'll either have to start Chatsuck or a AAA. And that probably means a short outing, thus taxing the BP.
