OK, he won!
but I'm quite disturbed by the comment about not caring after the first set. Even if he knew he was through he should want to win every match, not only for the points but because that's his job. It just makes him seem lazy and as if he wants to do the minimum possible. I agree with him that the round robin is stupid, but I can't help feeling that if Federer or Nadal or various other players were in the same position, they wouldn't want to give up after the first set, they would want to win.
It seems like he lacks competitiveness, and if he wants to be a top ten player and a contender for big titles, he'll have to improve this.
