That's a load of crap. Nadal was moving better than 99% of the tour yesterday, he just got a beat down put on him.
That said, Nadal probably wasn't serving at 100%, but Nadal made no excuses after the match. He took it like a man.
Del Potro may have finally arrived, we'll see today. But the beating he put on Nadal yesterday was just amazing. He totally dominated Nadal, who basically had no answer. Del Potro's offense just overwhelmed Nadal's defense.
If Del Potro plays as well against Federer, Federer will definitely earn the title if he can win. I was really awestruck by how well Del Potro played yesterday. His groundstrokes remind me of George Foreman's punches, slow handspeed, but heavier than hell.
