WIMBLEDON, England — Sabine Lisicki ended Serena Williams' long winning streak, she ended her Grand Slam winning streak and she knocked the top seed, world No. 1 and defending champion out of Wimbledon on Super Monday.

Lisicki jumped on Williams early, survived a nine-game drought in the middle, then came back from a break down in the third set twice on her way to a 6-2, 1-6, 6-4 victory.

"I'm still shaking," an emotional Lisicki said in a post-match interview, covering her face with her hands to wipe away tears. "I'm just so happy."

It was the latest upset in a tournament that has had many: Defending champion Roger Federer and Rafael Nadal, Maria Sharapova and Victoria Azarenka all were out in the first three days. The No. 2 seed on the men's side, Andy Murray, did not join Williams on the list of casualties, rolling past Mikhail Youzhny of Russia 6-4, 7-6 (7-5), 6-1. Novak Djokovic also advanced, defeating 35-year-old Tommy Haas 6-1, 6-4, 7-6 (7-4).

"I probably couldn't be more disappointed," Williams said. "I think I may have backed off of a success. I was playing something successful. I didn't continue that path. The result didn't go the way it could have gone had I continued to play the way I did in the second set."

Williams was up a break twice in the third set but Lisicki fought back both times and broke again to go up 5-4. She converted her second match point with a forehand winner.

In her post-match news conference, Williams mixed praise of her opponent with plenty of self-criticism.

"I didn't play the big points good enough. I didn't do what I do best," Williams said. "Sabine played really well, she always does well at Wimbledon, so I knew it would be a tough match going in. ... Definitely had opportunities, but I didn't take them."

Williams had won 34 consecutive matches before running into the big-serving German, who matched Williams' power and exploited the American's nervous mistakes.

Williams said it was her serve — usually her main weapon — that let her down in the third set.

"I felt that I was on the verge of winning," she said. "At that point I just was physically unable to hold serve. ... You have to be ready and willing to hold your serve. I wasn't willing or able, probably didn't even want to hold my serve today."

Lisicki reached the semifinals at the All England Club in 2011 but this will rank as arguably her biggest victory at the grass-court Grand Slam.

Lisicki has defeated the reigning French Open champion at Wimbledon three years in a row and four times in the last five years.

"I went into the match believing I could win," Lisicki said.

Patrick Mouratoglou, who coaches Williams, suggested she might be a bit worn down.

"Maybe she is a bit tired. That is a possibility," he said. "She's human. You cannot expect for anybody even if she is the greatest player of all time, if she is, to be perfect on all the matches all the year. She is not and she will never be. I think still that her low level is better than it was before. But she is a human. She is going to lose some matches and we have to be ready for that."

Sloane Stephens becomes the last American in singles, just as she was at the Australian Open. She defeated Monica Puig of Puerto Rico 4-6, 7-5, 6-1. Stephens will face Marion Bartoli of France in the quarterfinals.

Also Monday:

•Agnieszka Radwanska of Poland, the No. 4 seed, defeated Tsvetana Pironkova of Bulgaria 4-6, 6-3, 6-3. Radwanska lost in the final last year.

•2011 French open Li Na won a matchup of 30-somethings to reach the quarterfinals of Wimbledon for the third time, routing Roberta Vinci of Italy 6-2, 6-0.

•2011 Wimbledon champion Petra Kvitova became the first player to reach the quarterfinals, beating Carla Suarez Navarro of Spain 7-6 (7-5), 6-3. She was joined minutes later by Kirsten Flipkens of Belgium, who reached her first career Grand Slam quarterfinal by ousting Flavia Pennetta of Italy 7-6 (7-2), 6-3 — a year after her ranking plummeted as low as 262nd because of injuries.

•Laura Robson failed in her quest to become the first British woman to reach the Wimbledon quarterfinals since 1984, falling 7-6 (8-6), 7-5 in an error-filled match to Kaia Kanepi of Estonia. "I had my chances here and there and I just didn't take them," Robson said. "At that point, I was just trying to will myself to play unbelievable tennis when just making a serve would have been fine. But, as cliche as it sounds, it's all part of the learning experience. The more I get myself into those kinds of situations, the more I'm going to benefit." Kanepi will face Lisicki.

•On the men's side, fourth-seeded David Ferrer overcame another slow start to reach the quarterfinals with a 6-7 (3-7), 7-6 (8-6), 6-1, 6-1 victory over Ivan Dodig of Croatia.

•Tomas Berdych of the Czech Republic defeated Bernard Tomic of Australia 7-6 (7-4), 6-7 (5-7), 6-4, 6-4. Berdych will face Djokovic in the quarterfinals.

•Playing with his left knee heavily taped following a scary fall in the previous round, Juan Martin del Potro didn't let it slow him down as he beat Andreas Seppi 6-4, 7-6 (7-2), 6-3.

Del Potro twisted his left ankle and hyper-extended his knee during the third set of his win over Grega Zemlja on Saturday, and said he has been icing the knee constantly since.

He said "it's really painful," but that "the doctors are helping me" stay fit enough to play.

•Poland will send two men into the Wimbledon quarterfinals for the first time after 24th-seeded Jerzy Janowicz and 130th-ranked Lukasz Kubot each won five-set matches.

They'll play each other Wednesday with the winner becoming the country's first Grand Slam semifinalist.

The big-serving Janowicz reached as high as 137 mph while outlasting Jurgen Melzer 3-6, 7-6 (7-1), 6-4, 4-6, 6-4, while Kubot defeated Adrian Mannarino 4-6, 6-3, 3-6, 6-3, 6-4.

•Fernando Verdasco of Spain beat Frenchman Kenny De Schepper 6-4, 6-4, 6-4.
