So there is virtually no way Nadal could come back at this point, right? Even if he is waiting for some kind of pain medication to kick in or something, there was a chance Wawrinka was going to beat him anyway, regardless of whatever injury he is dealing with right now.
Here at GBS, we do tend to pull for the "underdog," which at this point is clearly Nadal. I wouldn't mind seeing some kind of miracle in the form of a Nadal comeback. But I think we're likely about 20 minutes away from me being able to take a nap!
