Rafael Nadal bounced in quarterfinals

— -- MELBOURNE, Australia -- Tomas Berdych showed No. 3 seed  Rafael Nadal the door Tuesday in the quarterfinals of the Australian Open, beating him in straight sets for the Czech's first win over the Spaniard in 18 matches dating to 2007.

The seventh-seeded Berdych fully controlled the first two sets in the 6-2, 6-0, 7-6 (5) win, handing Nadal his first set sweep since 2006 at Wimbledon and only the third at a Grand Slam in his career.

"I was ready for everything and I think that was the difference," Berdych said. "I started pretty well, but when you're playing Rafa you have to keep going to the last point."

Nadal hadn't lost a 6-0 set at any tournament since 2011. He failed to convert any of his four break-point chances.

"It is obvious that I needed something more to be more competitive," Nadal said. "As I said when I arrived here, the process always is not easy. When you have injuries, comebacks are difficult. But without being at my top level of tennis, I was able to be here in quarterfinals. Is not a bad result at all for me."

Nadal, a 14-time Grand Slam singles champion, said before the tournament began that his lack of match fitness due to injuries and illness in the last half of 2014 made him unlikely to win more than a few rounds at Melbourne Park.

Coming into the Australian Open, Nadal had played only eight matches since last June because of a right wrist injury and appendix surgery in November.

Berdych showed little emotion throughout the match, maintaining a familiar focus. He said he planned to continue to play in that style.

"If this keeps me going through, I'm going to keep doing the same," Berdych said.

Nadal saved two match points in the 12th game of the final set, sending it to a tiebreaker. Berdych led 5-2 and finally ended the match on his fourth match point when Nadal netted a return of serve.

Berdych will next meet Andy Murray or local hope Nick Kyrgios, who were to play the other men's quarterfinal set for later Tuesday.

The 19-year-old Kyrgios, who beat then-No. 1 Nadal in the fourth round at Wimbledon last year, defeated Andreas Seppi in the fourth round, the player who knocked Roger Federer out of the tournament.

The other men's semifinalists will be determined on Wednesday when top-seeded Novak Djokovic plays Milos Raonic and defending champion Stan Wawrinka takes on U.S. Open runner-up Kei Nishikori in quarterfinals in the other half of the draw.
