sad to see Nadal's conqueror go out
No way! It's the best! If Rosol had made it to (say) the quarters, he would be partially vindicated, and Nadal himself could justify his loss by saying "Oh, at least he made it this far..." Since he's out, though, Nadal must live with the knowledge that had he somehow beaten Rosol, he would've easily made it to the semi's, and likely the finals.
Oh yes, I'm an evil person.
