ASPEN, Colo. - Czech Sarka Zahrobska won the women's World Cup slalom here Sunday ahead of Austrians Marlies Schild and Kathrin Zettel.

"The conditions were really icy, and that's something I like," Zahrobska said.

America's two-time overall World Cup champion Lindsey Vonn, however, was less pleased after skiing off the course less than halfway into her opening run.

"It's just a little bit too icy for the girls. I don't think it does anyone a service to have it this difficult," Vonn said. "It's essentially like pond ice. It's like ice skating ... it's not ski racing anymore."

Vonn's disappointment was part of a dismal day for the US team, with no Americans advancing to the second leg.

"Embarrassing," said US women's coach Jim Tracy, who declined to blame the conditions. "No excuses. We just didn't ski the way we were supposed to ski, simple as that."

Zettel, who finished second in Saturday's giant slalom seized the lead in the overall World Cup standings from Finland's Tanja Poutiainen, who didn't start because of a back injury.

Zettel leads the overall standings with 22o points, followed by Germany's Maria Riesch on 176 and Poutiainen on 165.

The race also marked a return to form of Schild, 13 months after she broke her left leg in a training crash.

"It's a big surprise," said Schild, who won two medals at the 2006 Turin Olympics. "I had a hard year the last year, with my injury, with everything.

"I did not know if it would work again as well as it did before. It worked really good today."

German sisters Susanne and Maria Reisch missed out on podium places, settling for fourth and fifth.

Maria Reisch, reigning World Cup slalom champion and winner of the first slalom of this season at Levi, Finland, remained atop the discipline standings with 145 points, with Zahrobska second on 132.
