I was worried for Rafa against Nick but he pulled through, so this time i'm backing him to do it in four sets. But it must be a decisive, dominating 4 set victory, I feel a 5 set epic would be too much for Rafa. Thiem is playing well without being spectacular. The point is can he be consistent enough to go for his winners without making lots of errors, that's the key. It really underlines how easy Novak's draw has been. He'll literally sleepwalk his way to the final.
