MELBOURNE, Australia (AP)—Andy Roddick lost to Stanislas Wawrinka on Sunday, 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.

Federer matched a Grand Slam record which magnified his extraordinary consistency over eight years, while Francesca Schiavone established a record for endurance in a women’s singles match.

Day 7 at Melbourne Park was a day of new marks for the majors.

Federer beat Tommy Robredo 6-3, 3-6, 6-3, 6-2 to reach the quarterfinals for the 27th major in a row. Jimmy Connors set the Open era mark by making 27 consecutive quarterfinals in the Grand Slam events he entered between 1973 and 1983—although he didn’t play every major either due to injury or because he didn’t travel to Australia.

French Open champion Schiavone also established a Grand Slam record, needing 4 hours, 44 minutes for her 6-4, 1-6, 16-14 fourth-round win over Svetlana Kuznetsova.

Schiavone saved six match points, then converted on her third match point in the longest women’s match at a major in terms of time in the Open era. The longest previous record was set here last year when Barbora Zahlavova-Strycova beat Regina Kulikova 7-6 (5), 6-7 (10), 6-3 in 4:19.

The 30-year-old Italian battled exhaustion but, “at the end, you have something more, always.”

“Was for me, fantastic,” she said. “When you’re in a situation like this, every point is like a match point. You have to keep going. You know that physically you’re tired. Mentally just keep going.”

Kuznetsova said the match was so long she was forgetting the score or who should serve.

Schiavone said it wasn’t quite that bad for her, “but I was watching the clock, and I say—‘Bravo, Francesca, you are tough!”’

Schiavone will meet top-ranked Caroline Wozniacki in the quarterfinals.

Shortly after, 2008 champion Maria Sharapova lost 6-2, 6-3 to Andrea Petkovic, who had a relatively easy run into the fourth round when Venus Williams retired after just four minutes in their third-round match. Sharapova said it was just a “bad day in the office.”

Petkovic will now take on China’s Li Na in the quarterfinals.

“Maria is such a great champion, it’s just two or three points and she comes back, and she started playing so well in the last couple of games, so I was a little nervous,” Petkovic said.

Federer 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.

Federer, seeking a fifth Australian title, 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.”

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

Wozniacki moved into the Australian Open quarterfinals for the first time with a 6-3, 6-4 win over Anastasija Sevastova and is just one victory from ensuring she’ll retain the top ranking.

The 20-year-old Dane, playing her first major as world No. 1, can keep her top ranking with an appearance in the semis.

The questions about Wozniacki’s worthiness of the top ranking are starting to diminish. Asked which player she feared most, she said: “I don’t fear anyone actually.”

“I’m feeling confident. I feel like I can beat anyone on a good day. I think they have to fear me when they’re playing me,” she said. “I just go out there and do my best. If they’re better than me that day, it’s just too good.”

Wozniacki lost three of the first four games of the match before reeling off six in a row to take control.

She now has reached the quarterfinals at all four majors, and she’s navigated some troublesome ground. According to the WTA, only one of the last five women to be ranked No. 1 went beyond the first round in the first major they played with the top ranking.

She also steered herself in and out of trouble after telling a story in a post-match news conference about being scratched by a kangaroo.

After her match, she described an up-close encounter with a baby kangaroo that had scarred her.

She said she tried to pet the kangaroo and it scratched her, and noted she had seen a doctor and rejected advice to get stitches.

But she later tweeted: “Round 2 with the media:) hope you enjoyed my kangaroo story, hope you know i was just kidding:) see you on tuesday for round 3!”

She later returned to Melbourne Park to clarify she’d made up the story and to apologize, saying she didn’t think anyone would believe it.

Li, already China’s most successful player, reached the quarterfinals with a 6-3, 6-3 win over eighth-seeded Victoria Azarenka of Belarus.

The ninth-seed was one of two Chinese players to reach the semifinals at Melbourne Park last year, her run ending with a loss to eventual champion Serena Williams in two tiebreak sets.
