posted her first World Cup victory in leading a 1-2 Swiss finish in a super-G in Val d'Isere, France, and
placed third to retake sole possession of the lead in the overall standings.
The 28-year-old Aufdenblatten upset the favorites to finish in 1 minute, 26.43 seconds on the Oreiller-Killy course, 0.23 seconds ahead of Nadia Styger. Aufdenblatten's previous best World Cup result was the third place she twice took in downhills.
"Somebody told me that it happened after more than 200 races," Aufdenblatten said of her winning drought.
Vonn was 0.26 seconds back in third to regain sole possession of the overall World Cup lead with 581 points, 50 more than Germany's Maria Riesch.
The race was interrupted for about 15 minutes when Marie Marchand-Arvier, of France, fell heavily and was evacuated from the slope on a sleigh with suspected cranial trauma. The super-G silver medalist at the world championships was expected to undergo a scan.
