Third seed and 2008 champion Novak Djokovic looked in astonishing form today when he beat Uzbek Denis Istomin in straight sets with a loss of just four games. Djokovic broke Istomin several times in the match and completed the 6-1, 6-1, 6-2 victory in almost 90 minutes of play.

In another swashbuckling performance, Russian Nikolay Davydenko fired past Argentine Juan Monaco 6-0, 6-3, 6-4 to set up a pre-quarterfinal clash with Fernando Verdasco, last year's semifinalist, who comfortably moved ahead in the draw when his opponent Stefan Koubek retired from the match after losing the opening set 6-1. Davydenko is in impressive form and has beaten both Federer and Nadal in all his previous meetings with them.

"Really, it's difficult to say why it's happening. Maybe it's good. I was feeling today was much better my concentration in a match. And beginning start already. I fighting for every point, and that's what maybe it was 6 Love in the first set and 3 Love. Because like say I didn't make it any mistake, you know, like say nine games," said Davydenko about his phenomenal form.
