(CNN) -- Lindsey Vonn showed she is in sparkling form ahead of next week's world championships by winning a World Cup slalom in Garmisch-Partenkirchen on Friday.
Vonn turns on the style to extend her lead in the overall World Cup standings.
The United States racer was claiming her fourth win of the season and extends her lead in the overall World Cup standings over closest rival Maria Reisch of Germany.
Reish finished second to Vonn, nearly one second down after the two runs, with Slovenia's Marusa Ferk in third place.
Vonn has 1014 points in the overall standings, 124 clear of second-placed Riesch ahead of the final women's event before the world championships, a super-G on Saturday.
Austria's Kathrin Zettel of Austria led after the first run, but was disqualifed while compatriot Michaela Kirchgasser, who was second, fell second time down.
Vonn, third after the first run made no mistake for a combined time of one minute 47.17 seconds at the famous German ski resort.
Reisch leads the standings in the slalom discipline by 140 points from Vonn.
On the men's World Cup circuit, Austrian veteran Hermann Maier set the fastest time in practice for Saturday's downhill at Garmisch with a one minute 43.79 seconds clocking on the Kandahar course.
The world championships start in Val d'Isere, France on February 3, an important pointer to the Olympics in Vancouver next year.
