I'm not worried about Lorenzen if he's not going to be a starter going forward. I think it's still more likely that he was just going to hit the wall/had reached his career high in innings than it is that the no-hitter did it. The same would have gone for Strahm (and he was definitely worrisome for a while too).
Obviously if he's an injury waiting to happen that would be a whole other issue. But if he just has to make 2 or 3 more starts and then be a 2-3 inning playoff pitcher hopefully he's ok. Right now it's moot when Suarez is out, but easy call to leave Sanchez in the rotation if Ranger is back soon. Whether they go six-man or tandem or whatever they can find some rest for Lorenzen.
Hopefully Walker's all right. They can afford to have one weak spot, but not two.
Still a little soon to feel great about Nola too IMO but it's also moot because I don't see any scenario where he's not still the Game 2 shorter (ok, that scenario would be 2-3 bad starts. But the current pattern, nope, Thomson won't not go with him).
