I'm not sure about the Sox starters, but that's the way I see the Yankees rotation.
Oh, I should also mention that Kim Jones said on the pregame that there's a chance that the Saturday start might go to Wang instead of Karstens. That would be a desperate move in my opinion, considering the Yankees were saying they wanted to give him two starts and he wouldn't be able to make another start if they did that. If they did do that, I'm not sure if that means Karstens would start Sunday, but I wouldn't expect to see Wang anyways.
