Here are some highlights from Day 7 in London. Watch video
TRACK
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 heptathlon's first event and the highlight of a raucous opening session for track and field. [VIEW PHOTOS]
SWIMMING
Michael Phelps' last individual race at the Olympics ended like so many of the ones before it — with his hands on the wall before everyone else in the pool.
Phelps rallied to win the 100-meter butterfly for his third gold of the London Games and No. 17 of his career. The American was next-to-last at the turn but closed strong to finish in 51.21 seconds, just ahead of Chad le Clos of South Africa and Evgeny Korotyshkin of Russia. Phelps' final Olympic race will be the 4x100 medley relay Saturday.
Phelps' 21st medal was part of another big night at the pool for the U.S., led by a pair of teenagers.
Missy Franklin set a world record in the 200 backstroke for the 17-year-old's third gold in London. And right after Phelps was done, 15-year-old Katie Ledecky — the youngest member of the U.S. team — nearly broke the world record while winning the 800 freestyle, denying Britain's Rebecca Adlington a repeat before her home fans.
Florent Manaudou of France took the 50 freestyle in 21.34 seconds. American Cullen Jones grabbed the silver medal and Brazil's Cesar Cielo was third.
It was also an exciting day at Wimbledon where Roger Federer clinched the first singles medal of his career in an Olympic marathon, winning 19-17 in the final set against Juan Martin del Potro. With the comeback victory, four-time Olympian Federer is assured of at least a silver. On Sunday he'll play in the final against the winner of the second semifinal between No. 2-seeded Novak Djokovic of Serbia and No. 3 Andy Murray of Britain.
Serena Williams will face first-time Olympian Maria Sharapova in the final, who beat Russian teammate Maria Kirilenko 6-2, 6-3 in the semifinals. Williams earned her berth in the final when she beat No. 1-seeded Victoria Azarenka 6-1, 6-2.
WATER POLO
The Americans survived an 11-minute scoreless start before Maggie Steffens put in three goals and the rest of the offense got rolling to edge China 7-6 in the team's last preliminary-stage game of the London Olympics.
JUDO
It was over in little more than a minute, but it will be one of the signature moments of the Games. A young Saudi judo fighter's decisive defeat is hailed as a victory for women in the conservative Gulf kingdom. Wojdan Ali Seraj Abdulrahim Shahrkhani is one of just two women competing for Saudi Arabia at the games.
SOCCER
