MOSCOW -- Steve Omischl of Canada won the World Cup aerials title Saturday while Emily Cook of the United States captured her first World Cup event.
Cook totaled 160.41 points and defeated Deidra Dionne of Canada and Zhang Xin of China.
"It's really rewarding to go out and perform your best and be on the top of the podium," said Cook of Belmont, Mass. "I was shocked. ... I was at the bottom and had no idea I had won."
Before the 2002 Olympics, Cook shattered her feet and ankles while training in Lake Placid, N.Y. She underwent many operations and competed at the 2006 Turin Games.
This was the first time a World Cup freestyle aerials event was held on an artificial slope. A high tower was erected near Moscow University.
Omischl won his fifth event of the season. He scored 240.32 points and edged Stanislav Kravchuk of Belarus, who was second with 236.45. Nicolas Thepaut of France finished third.
Omischl, the 2005 world champion, leads Anton Kushnir of Belarus by 84 points with one event remaining next week in Davos, Switzerland. Kushnir was 12th Saturday after falling on his second attempt.
In a dual moguls event in Marianske Lazne, Czech Republic, Guilbaut Colas of France and Aiko Uemura of Japan won the men's and women's competitions.
Colas edged American Nathan Roberts in the final while Alexandre Bilodeau of Canada beat Russia's Andrey Volkov for third place.
Olympic champion Dale Begg-Smith of Australia leads the overall standings with 439 points with three more events remaining. Colas is second, 15 points behind, and Bilodeau third with 315.
Uemura beat Canada's Sylvia Kerfoot, who crashed in the final, to take the lead in the overall standings with 383 points. Emiko Torito of the United States was third, followed by Alizee Boulangeat of France.
Margarita Marbler of Austria dropped to second in the season standings with 370 points after finishing fifth.
