Nadal basically got his USO the same way Fed got his FO. Just hang in there long enough until the perennial champ finally falters. The difference being Federer was actually the 2nd best clay player since 2005. You can't say the same for Nadal on hardcourts.....and Federer's draw at the 09' FO was not cupcake at all.
