BEIJING (AP) — Shawn Johnson's smile was a thousand times wider than the balance beam she had just conquered. Finally, it was a golden grin.

The world champion made a habit of collecting silver at the Beijing Games, and she never stopped smiling. But it wasn't exactly what she came to China for. She ended her runner-up streak with a beam routine Tuesday night that blew away the field, including all-around champ Nastia Liukin, behind whom Johnson got one of her three silvers.

"It's crazy," the 16-year-old Johnson said. "I remember seeing Nastia have hers from the all-around and it is so pretty. Silver is really pretty, too.

"It's the best feeling ever."

Johnson won the gold despite a headache earlier in the day.

"This is what we expected to see," her coach Liang Chow said. "The thing I really am pleased with is she was a little under the weather and she still was able to do a wonderful routine."

Wonderful also describes the Chinese men throughout these Olympics. They swept the two events Tuesday, with Zou Kai winning high bar and Li Xaiopeng winning parallel bars. In all, China took all but one men's event, the vault — in which there was no Chinese finalist.

China's men won the team title, Yang Wei took the all-around, and the Chinese also took the still rings, pommel horse and floor exercise.

The United States got its only men's individual medal when Jonathan Horton soared through an energetic high bar routine that drew almost as loud a roar as Zou's performance. Horton was second to Zou and also won bronze with the U.S. men in the team finals.

Even more impressive, Horton changed his routine three days ago, after the all-around final, in which he finished ninth.

"I hit the floor and I looked at Mark," he said of coach Mark Williams, "and said, 'Can you believe that just happened? I knew instantly I was going to medal."

Altogether, the Americans won 10 medals; the U.S women won eight, compared to six for China. The 10 medals surpassed the U.S. total of nine in Athens.

Liukin got a gold, three silver and a bronze to tie the record for an American in one games.

"I'm really happy for her," Liukin said of Johnson, her roommate in Beijing. "Three silvers is kind of hard to take. I couldn't be more proud of her."

National team coordinator Martha Karolyi was ecstatic. After a disappointing start, when the Americans bumbled their way out of a team gold that went to China, they came back with a surge of strong showings.

"This was the right ending to conclude the Olympic Games," Karolyi said. "We proved the supremacy of U.S. women's gymnastics.

"I feel excellent (about Johnson). I think she needed this so much. She proved she is absolutely a great balance beam gymnast."
