Like all ballbashers, he will have a hot streak, and then play crap for the rest of the year. Book it.
He looked good against Nadal, on the baseline, but Nadal isn't 100% or even close to it.
I wouldn't be surprised if he made a slam final though, but I would put money that he won't be ranked above #5 - Nadal was just being overly courtagious because he won the match.
I'll book it, babe.
