Madrid:Roger Federer overlooked his recent history against Guillermo Canas, routing the 14th-ranked Argentine 6-0, 6-3 on Thursday in the third round of the Madrid Masters.
Canas, who beat Federer in consecutive tournaments in March, was broken at love in the second game.
Two more breaks of serve gave Federer the first set in 21 minutes.
"I played aggressively, took my chances and felt in control. It was nice to beat him, that's for sure," Federer said.
Canas held serve for 1-1 in the second set. But Federer, the defending champion, abandoned the groundstrokes and came to the net.
He scored 14 of his 17 overall winners at the net in the second set.
Federer, who won 32 of his 41 service points, broke Canas again in the sixth game before holding serve for the rest of the way.
Federer next will play Feliciano Lopez after the Spanish wild card beat Austrian qualifier Stefan Koubek 7-6 (9), 6-1.
Canas defeated the top-ranked player in earlier in the year at Indian Wells, and Miami but the indoor surface favored Federer.
"I was especially disappointed with the Miami loss, so to beat him later in the year after two tough losses is nice. I think the surface was much slower in Indian Wells and Miami. And I didn't know his game so well then," Federer said.
Juan loses to Fernando
Earlier, fifth-seeded Fernando Gonzalez of Chile defeated Juan Monaco of Argentina 6-4, 6-2 to set up a quarterfinal match with Nicolas Kiefer of Germany, who beat Ivo Karlovic 7-6 (5), 7-6 (3).
Third-ranked Novak Djokovic beat Juan Carlos Ferrero of Spain 6-3, 2-6, 6-4 to advance to the quarterfinals.
Djokovic will play Mario Ancic, who beat Paul-Henri Mathieu of France 6-4, 6-3.
"I haven't played so far on the level that I can, but the most important thing is that I won," Djokovic said.
Ferrero's last title was the 2003 Madrid Masters, a stretch of 88 tournaments.
Djokovic had the decisive break in the eighth game before clinching the first set with one of his five aces.
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 Djokovic's drop shot and tapped it past him for a second break in the eighth game to even the match.
He broke Ferrero to lead 2-0 in the third set and maintained that advantage to close it out.
"It's been a long year and I've played a lot of matches. And, maybe in some stages, physically and mentally I don't look so effective," Djokovic said.
