5-4 - The biggest cliche in football is that Peter Crouch has good feet for a big man. In tennis it is that Karlovic has good touch at the net for a big man. He plays some nice serve and volley, showing nice hands at the net to flick home the winners.

4-3 - Tsonga decides to gamble on Karlovic's serve and steps to the backhand side and plays the shot, the only problem was the ball went down the middle. An ace to start and an ace to finish.

3-2 - Tsonga plays a classic drop shot at the net to draw his opponent in and then passes him with a forehand. That gets his nose in front at 30-15.

1-1 - Equally, Tsonga has no trouble whatsoever, he also holds to 15, with Karlovic putting the ball into the net to seal it.

- - These two have never met on the tour before, but have met in a challenger event, which Tsonga took in straight sets. Karlovic has not dropped a set so far, Tsonga has dropped one. In the last round Tsonga had a walkover due to his opponent pulling out.
