I finally watched Federer's match against Karlovic in the Cincinnati Masters. It was tense and so damn frustrating. Federer's tennis is still amazing but it felt as if he wasn't putting his all in the game. It is like his loss at Wimbledon has knocked something out of alignment in his mind and it is just so damn frustrating because it feels as if his heart is not in the match. Nadal can be #1 but not like this.
