Lindsey Vonn of USA speeds down the course during the downhill portion of a women's alpine skiing super-combined World Cup race in St. Moritz, Switzerland, Friday, Jan. 27, 2012.

ST. MORITZ, Switzerland — Lindsey Vonn won a World Cup super-combined event Friday to extend her lead in the overall standings against second-place Tina Maze.

The American defended her lead from the morning downhill with a solid slalom leg to clock a combined two-run time of 2 minutes, 28.35 seconds.

Maze of Slovenia was 0.41 seconds back and third-place Nicole Hosp of Austria trailed Vonn by 0.58.

Vonn earned 100 World Cup points for the victory and leads Maze by 302. The 48th career World Cup win began her defense of the season-long super-combined title.

Vonn won the super-combined title the past two years. She has seven victories this season in her quest to regain the overall crown.

She held her nerve when Maze and Hosp put down the two fastest slalom runs after they finished the downhill sixth and seventh, respectively.

Elisabeth Goergl of Austria was second in downhill, 0.61 behind Vonn, but skied out in the slalom.

Defending overall champion Maria Hoefl-Riesch of Germany had a big mistake midway down the slalom and hiked up the mountain to resume her run. She finished 21st, more than five seconds behind the leader.

The Olympic champion in super-combined was third after the morning run.

Hoefl-Riesch is winless this season after denying Vonn a fourth straight giant crystal globe last year.
