Austria's Katharina Liensberger led after the first leg of the women's slalom at the Alpine skiing world championships on Saturday as Mikaela Shiffrin's hopes of a record fifth successive title dimmed.
Shiffrin is the U.S. skier with most world championships golds (six) and medals (10).
Liensberger, who already has a shared parallel gold and giant slalom bronze, was the first of 107 starters and completed the 62-gate run with a time of 48.48 seconds on a bright morning in the Dolomites.
Slovakia's overall World Cup leader Petra Vlhova was in second place, with 0.30 to make up in the second leg, while Switzerland's Wendy Holdener was third and 1.24 off Liensberger's time.
Switzerland last won a world championships women's slalom with Vreni Schneider in 1991.
Between them, Shiffrin and Vlhova have won all but one World Cup slalom since January 2017.
Italy's Federica Brignone ended her championships in disappointment, the reigning overall World Cup champion hitting a gate and falling in her last attempt to medal on home snow.
Switzerland's Michelle Gisin, bronze medallist in the combined and the only skier to break the Vlhova-Shiffrin World Cup slalom stranglehold, also failed to complete the first run as did Austria's Katharina Huber.
