Day 11 of the Olympic Games brought victories and disappointments to American athletes.
U.S. hopes for gymnast Gabby Douglas to repeat her gold-winning form Tuesday were dashed as she took a tumble from the balance beam -- but it was a day of joy for her teammate Aly Raisman, as Raisman claimed bronze in that event followed by a gold in the floor exercise.
Raisman, who just missed out on a medal in the women's individual all-around, beat Catalina Ponor of Romania and Russia's Aliya Mustafina to clinch victory.
"It was the best routine I've ever done," she said. "My coach said it was the best routine he'd ever seen me do."
She took the third spot in the beam after a U.S. challenge to the initial results saw Ponor pushed down to fourth. China's Deng Linlin and Sui Lu took gold and silver, respectively, in that event.
The pint-sized Douglas swung back onto the beam to continue her routine, but the slip was too costly for her to place better than seventh.
Douglas, nicknamed the "Flying Squirrel" for her aerial agility on the uneven bars, has won a new legion of fans after her thrilling win in the women's individual all-around early in the Games, but has seen medal chances slip through her fingers since.
The 16-year-old's unfortunate mistake on the balance beam followed disappointment in the uneven bars Monday, when she came in eighth.
"It was an amazing finals with so many great competitors," she said after Monday's event. "Coming into bar finals was a big challenge for me, and I made a little mistake. Even if I would have hit a solid routine, I know I have a lower start value than the other competitors."
Victory in the men's parallel bars went to China's Feng Zhe, ahead of Germany's Marcel Nguyen in silver position and France's Hamilton Sabot..
Happy hosts crown new medals king
Great Britain celebrated eight medals Tuesday, giving it 48 for the Olympics, one more than for the 2008 Beijing Games. Team GB has won 22 golds, most since the 1908 Olympics, also held in London.
There was early disappointment for Team GB, though, as triple jumper Phillips Idowu failed to make it through the qualification round. The athlete, an east London native and Beijing silver medalist, had been the focus of much injury speculation in the run-up to the Games.
Joy and tears were in evidence in the velodrome, the scene of a moving end to two great British Olympic cycling careers.
Chris Hoy took the top spot in the men's keirin cycle race, making him the first British Olympian to win six gold medals.
"I'm in shock," Hoy told the BBC, official broadcaster for the Games. "This is just surreal, this is what I always wanted, I wanted to win gold in front of my home crowd."
Hoy, now 36, said he was 99.9% sure he would not be competing in Rio de Janeiro in 2016. "This is the perfect end to my Olympic career," he said.
But Britain's Victoria Pendleton was denied a similar fairytale ending when Australia's Anna Meares took gold in the women's track cycling sprint after a dramatic finish, leaving her with silver.
An emotional Pendleton, who retires after these Games, said, "I can't believe it's all over." But, she added, "I'm very glad to be saying it's the last time I'm going to go through this."
The silver medal capped a week of ups and downs for the 31-year-old, who was disqualified from the women's team sprint alongside teammate Jess Varnish last week but then won gold in the women's keirin.
Team GB's Laura Trott won the women's omnium, a cycling contest made up of six events. American rider Sarah Hammer had been well placed going into the final stage but slipped down the rankings.
British track cyclists have won seven golds in these Games, while those from other nations have won no more than one each.
There was also early exaltation for the home crowds Tuesday, as brothers Alistair and Jonny Brownlee of Team GB split gold and bronze between them in the triathlon, with Spain's Javier Gomez winning silver.
Thousands of flag-waving spectators had flocked to watch the competitors in the men's triathlon swim in the chilly Serpentine lake, cycle laps of the Hyde Park area and run a final grueling 10 kilometers.
Alistair Brownlee strolled over waving a Union flag as he claimed an emphatic win -- Britain's first ever gold in the event -- while Jonny Brownlee made a brave recovery to take bronze after taking a 15-second time penalty for a bungled transition between phases.
