I find it unbelievable that Nadal would skip out the Olympics AND THE US OPEN after an "injury". I know that Nadal was having problems with his motivation during Wimbledon, and that is why he was upset by Rosol. I watched the match several times. Rosol did not "overpower" Nadal, it just seems that way. 130 MPH serves? Nadal trashes Roddick, who is arguably the best server ever. Rosol's overpowering ground strokes? ********. Soderling, Berdych, Tsonga have WAY more power. Nadal is in a slump, and 2013 will be Nadal's Calendar Grand Slam Year.
