HAUS IM ENNSTAL, Austria — Lindsey Vonn won a women's World Cup super-G on Sunday, becoming the first American to earn a victory on three straight days and the first women to do since 1997.

Vonn went down the Krummholz course in 1 minute, 26.69 seconds to beat Anja Paerson of Sweden by 0.53 seconds.

Vonn's 28th World Cup win moved her past Phil Mahre into second on the career victory list for American skiers. Bode Miller leads with 31 victories.

The last female skier to win on three consecutive days was Germany's Katja Seizinger in 1997 at Lake Louise, Alberta. Anna-Marie Proell of Austria and Marie-Therese Nadig of Switzerland also accomplished the feat in the 1970s.

"This gives me a lot of self-confidence, things couldn't have been better," Vonn said. "I knew I needed to race more aggressively than in my previous super-Gs this season. I gave my best and had a perfect run."

Nadia Fanchini of Italy and Martina Schild of Switzerland shared third place, 0.85 behind the American, who extended her lead in the overall standings over Maria Riesch of Germany.

Vonn won downhill races Friday and Saturday here.

She came close to earning three victories in three days in December, winning back-to-back downhills before finishing second in a super-G race the next day in Lake Louise, Alberta.

"I am not unbeatable in speed events," Vonn said. "Everyone can race the same line as I do. I know some girls are just as fast as me in training, but what counts is that you deliver it in the race."

Vonn said her performances on the World Cup circuit will help her at next month's Vancouver Olympics.

"Doing well in the World Cup is the ideal preparation," she said. "We have speed weekends coming up in St. Moritz and Cortina d'Ampezzo. It's not easy to win every time but main thing is: I'll be fast again."

Riesch finished 24th, 2.65 seconds behind Vonn, after skiing off-course in the final section of the run.

Vonn has 894 points, 192 clear of Riesch. Austria's Kathrin Zettel is next with 569, followed by Paerson with 551.

Riesch looked set for a podium finish but misjudged a sharp turn and almost came to a standstill.

"I am not in a crisis," said Riesch, who was seventh in Saturday's downhill. "Lindsey was just too good this weekend. And I have to focus on the positive aspects, as I was skiing really fast before that mistake."

Paerson was happy with her second podium finish after taking second in Friday's downhill, the first time she had come in the top three since February.

"I am very proud with second place. It was a difficult turn but I tried to be aggressive," Paerson said. "Lindsey is not unbeatable, there are more races this season than just in Haus. Every race is a new one."

The women's World Cup circuit continues with a night slalom on Tuesday in Flachau, Austria.
