Re: Who will start Game 4?
I don't think losing Cueto for NLCS should factor into the NLDS starter decision because:
1) If you are pitching Cueto in the NLCS, it should be game 4 of NLCS to give him max rest before you use him, so he would only pitch 1 game of NLCS.
2) If you are pitching Cueto in the NLCS, then Leake is on the roster, because you need to plan to have him for an all hands on deck situation in Game 4 if Cueto falters. So you might get Leake pitching NLCS game 4 any way.
Given those 2 condition, I think they should sacrifice the possibility of Cueto pitching game 4 of NLCS and DL him, then you get the best 2 options of winning a 3rd game in the NLDS. Leake vs Zito and Latos versus Cain at this point are the 2 matchups possibilities that give Reds best chance of winning a 3rd NLDS game. Without that 3rd NLDS win, the NLCS conversation never takes place.
