LONDON Five things to know about Friday, Day 7 of the London Olympics:
Threepeat achieved: Michael Phelps wins last individual race at Olympics.
Saudi womans judo appearance hailed as victory for women in ultraconservative kingdom.
Track and field gets under way with fans filling up stadium.
Roger Federer, Serena Williams reach Olympic tennis finals.
U.S. men shut out in boxing; worst showing ever.
Wojdan Ali Seraj Abdulrahim Shahrkhani became the first Saudi woman to compete at the Olympics when she lost her judo fight in 82 seconds. And she only made it to the mat after a compromise between Olympic organizers, the international judo federation and Saudi officials cleared the way for her to wear a modified hijab.
The crowd roared right before Shahrkhanis fight against Puerto Ricos Melissa Mojica. The Saudi, wearing judo dress and what appeared to be a tight-fitting black cap, looked tentative and cautious on her feet, and Mojica eventually grabbed Shahrkhani and flipped her onto her back, ending the match.
As she rose to her feet, Shahrkhani gently reached for her head to make sure the hijab still was in place. It was, and the two women bowed to each other and left to a loud ovation.
Afterward, the teenager walked with her father past journalists and TV cameras.
I am happy to be at the Olympics, she whispered in Arabic, her brother, Hassan, holding both her arms. Unfortunately, we did not win a medal, but in the future we will, and I will be a star for womens participation.
Olympic Stadium was packed for the first time since the opening ceremony, and heptathlete Jessica Ennis gave the delirious crowd exactly what it was hoping to see.
Ennis finished the 100-meter hurdles in 12.54 seconds, the fastest time ever in the heptathlons first event and one of the highlights on a raucous opening day for track and field.
Ennis time matched Dawn Harpers gold-winning burst in the 100-meter hurdle final at the Beijing Games and wouldve been good enough to take that title at the 1992, 1996 and 2000 Olympics.
Amazing. So loud. When you step up to jump or get in your blocks, they really get behind you. Its a great feeling, Ennis said of the home crowd.
Polands Tomasz Majewski (mens shot put) and Ethiopias Tirunesh Dibaba (womens 10,000 meters) won the first gold medals in track and field, and world champion Carmelita Jeter of the U.S. led the 100-meter heats with a time of 10.83 seconds.
There were more stirring moments as Wimbledon, where Federer was pushed to the limit in his pursuit of his first Olympic singles medal.
Federer rallied past Juan Martin del Potro of Argentina 3-6, 7-6 (5), 19-17 to reach the final. At 4 hours, 26 minutes, it was the longest three-set mens match of the Open era.
I was very tense at certain times, Federer said. I was seeing myself as a loser many times during the match.
Federer faces another tough challenge when he meets Britains Andy Murray in Sundays gold-medal match. Murray, who advanced with a 7-5, 7-5 victory over Novak Djokovic, lost to Federer in the Wimbledon final.
Williams also clinched her first Olympic singles medal, beating No. 1-seeded Victoria Azarenka 6-1, 6-2. Today, Williams will face first-time Olympian Maria Sharapova, who beat Russian teammate Maria Kirilenko 6-2, 6-3.
Nine consecutive defeats appeared to finish off the American mens boxers until a late-night reprieve kept one U.S. fighter alive.
Raushee Warren and Errol Spence appeared to send the Americans home without a medal for the first time in Olympic history.
But about five hours after Indian welterweight Krishan Vikas appeared to clutch and grab his way to a 13-11 win over Spence, AIBA overturned the result of the bout, saying Vikas had committed nine holding fouls in the third round and intentionally spit out his mouthpiece in the second.

Minxia surged ahead with a brilliant final dive, a back 2½ somersault in the pike position. The crowd gasped when she sliced through the water, barely causing a ripple.
Ben Ainslie won the 10th race in the Finn regatta to set up a dramatic showdown in his quest to become the most successful sailor in Olympic history.
