LONDON — Ryan Lochte won the 400-meter individual medley, China collected a couple of gold medals and Australia set an Olympic record while winning the women's 400-meter freestyle relay.
Oh, and Michael Phelps went without a medal in an Olympic race for the first time since 2000.
It was quite the opening night at the pool.
There were 12 medal events on the first day of the London Olympics, and the U.S. came away with five — but only one gold.
After barely qualifying for the final, Phelps struggled to a fourth-place finish and was denied his 17th career Olympic medal. When it was done, he could barely get out of the pool.
Lochte took the gold with a time of 4 minutes, 5.18 seconds. Brazil's Thiago Pereira (4:08.86) settled for silver, while Japan's Kosuke Hagino (4:08.94) claimed the bronze.
"I think I'm kind of in shock right now," Lochte said. As for his defeated rival Phelps, "I know he gave it everything he had. That's all you can ask for."
The women's 400 individual medley went to 16-year-old Ye Shiwen, who set a world record with a time of 4:28.43. It was the third mark to fall since high-tech bodysuits were banned at the end of 2009. American Elizabeth Beisel took silver and China's Li Xuanxu grabbed the bronze.
Natalie Coughlin tied Jenny Thompson and Dara Torres for most career medals by an American woman with 12 when the United States won a bronze in the 4x100-meter freestyle relay. And she didn't even have to swim in a final: She swam a leg in the preliminaries, helping the U.S. qualify second-fastest. But for the evening final, the Americans went with teenager Missy Franklin and Jessica Hardy, and brought back Olympic rookie Lia Neal and Allison Schmitt, leaving Coughlin to play cheerleader.
In other events, the U.S. women's soccer team defeated Colombia 3-0 to earn a spot in the quarterfinals, and the U.S. men's gymnastics team had a strong start in the qualifying round as other teams stumbled. In volleyball, the U.S. held off late-charging South Korea 3-1 in their opening match.
Wimbledon champions Roger Federer and Serena Williams each won their opening matches. Four-time Olympian Federer beat Alejandro Falla of Colombia 6-3, 5-7, 6-3. Williams, seeded fourth, defeated former world No. 1 Jelena Jankovic of Serbia 6-3, 6-1 as first lady Michelle Obama watched from the front row of Williams' box.
China leads the medal count with six, including four gold medals. In winning her gold medal in the women's 400-meter individual medley, swimmer Ye Shiwen set the first world record at the Olympic pool. Teammate Sun Yang won gold in the men's 400-meter freestyle.
Outside the pool, China took gold medals in weightlifting and shooting. Weightlifter Wang Mingjuan won gold in the 48-kilogram category Saturday lifting a combined 205 kilograms. Yi Siling won the women's 10-meter air rifle final.
Italy's men's archery team beat out the U.S. for the gold, and Elisa Di Francisca captured a gold medal in fencing for Italy.
At the games
Fresh from her star turn as the latest Bond Girl, Queen Elizabeth II returned to Olympic Park for an encore.
The queen visited with British Olympians in the athletes village and rode to the top of the 377-foot Orbit tower beside the stadium, where on Friday night she officially opened the 2012 Games. Her husband, Prince Philip, and London Mayor Boris Johnson accompanied her.
In describing her role in the opening ceremony, created by director Danny Boyle, Johnson said the queen had told him she was "very, very impressed with the success of her first film appearance, her first dramatic venture. It was very funny and seems to have gone down particularly well with the international audiences."
The show-stopping moment featured the queen making her acting debut alongside Daniel Craig, who portrayed James Bond in a film beamed into the stadium.
The opening ceremony was the most watched of any winter or summer Olympics opening ceremony with 40.7 million people tuning in.
