Novak Djokovic said: "On the rare occasions like today, I do feel like Karlovic.
It's quite frustrating to play against a player like Ivo Karlovic, a player that serves very well. But it feels great when you actually can get out of your serve a lot of free points. And that was the case for me, not just today, but throughout this week.
I haven't dropped a set. Serve was one of the definitely best shot in my game and that allowed me to kind of also feel more comfortable and more confident from baseline."
