MELBOURNE, Australia -- Andy Roddick lost Sunday to Stanislas Wawrinka, meaning there will be no Americans in the men's or women's quarterfinals of the Australian Open.

Wawrinka's 6-3, 6-4, 6-4 win means two Swiss men will meet in a major quarterfinal for the first time in the Open era. Wawrinka will face defending champion Roger Federer, who matched the mark for most consecutive appearances in the final eight at Grand Slams.

"Obviously wasn't the showing that we wanted, you know, but I'm doing what I can," said Roddick, who said Wawrinka completely outplayed him.

Roddick, seeded eighth, had been the last American man standing in the singles field. The women were out before the third round ended. Venus Williams lasted only seven points before she hobbled off with an ailing hip muscle.

Since Roddick's 2003 U.S. Open victory, no American man has won a major. Venus and sister Serena Williams have won 10 majors between them in the interim, and 20 between them overall. Serena was the 2010 champion in Australia, but couldn't defend her title because of a foot injury.

"Not having the best player in the world at a major would be ... be tough for any country. Obviously we want her healthy as much as possible," Roddick said of Serena. "You know, she's instantly the best player in the game when she comes back."

Federer beat Tommy Robredo 6-3, 3-6, 6-3, 6-2 to reach the quarterfinals for the 27th major in a row.

Federer added another record to his vast collection, matching Jimmy Connors' mark for consecutive Grand Slam quarterfinals appearances.

Federer has reached the quarterfinals in 27 consecutive majors since his third-round loss in the 2004 French Open, equaling Connors' Open-era record.

The 16-time Grand Slam winner didn't concede a point on his serve in the first set, but had a lapse in the second when Robredo's serve was dominant and he took a set off Federer for only the third time in 10 matches.

"I was struggling with my return -- I couldn't get the balls into play I wanted to," Federer said. "I didn't have the best of games at 4-3 down -- we don't have much margin at the very top and it shows."

Federer regained control in the third set and dominated after getting an early break to lead 2-0.

"It's a lot of hard work. I'm sweating bullets right now," he said. "I'm excited to be in the next round."

He admitted he'd had a tough first week, including a five-set win over Gilles Simon.

"I'm in another quarterfinal. Got all the chances to make it to the semis again," Federer said, "so I'm very pleased."

No. 3-ranked Novak Djokovic is aiming for his second Australian crown. The 2008 champion advanced to the quarterfinals for the 13th time in the past 15 majors with a 6-3, 6-4, 6-0 win over No. 14 Nicolas Almagro and will next play 2010 Wimbledon finalist Tomas Berdych, who beat Fernando Verdasco 6-4, 6-2, 6-3.
