Federer makes quick work of Canas

Canas, who beat Federer in back-to-back tournaments in March, held serve to make it 1-1 in the second set.

But Federer, the defending champion, abandoned the groundstrokes and came to the net, scoring 14 of his overall 17 winners from there in the second set.

Federer broke Canas again in the sixth game before holding his serve for the rest of the way. In the quarter finals, Federer will play the winner between Spanish wild card Feliciano Lopez and Austrian qualifier Stefan Koubek.

Third-ranked Novak Djokovic beat Juan Carlos Ferrero of Spain 6-3, 2-6, 6-4 to also advance to the quarter finals.

Djokovic had the decisive break in the eighth game before clinching the first set with one of his five aces in the next game. Djokovic failed to convert any of five break points in the first game of the second set and Ferrero broke in the next game.

Ferrero, who saved five break points overall in the set, got to Djokovic8217;s drop shot and tapped it past him for a second break in the eighth game to level the match.

Djokovic will next play Mario Ancic after the Croat beat Paul-Henri Mathieu of France 6-4, 6-3. Djokovic, who was pushed to three sets against Fernando Verdasco on Wednesday, broke Ferrero to lead 2-0 in the third set and maintained that advantage to close it out.

Earlier, fifth-seeded Fernando Gonzalez of Chile broke three times to beat Juan Monaco of Argentina 6-4, 6-2.
