Chantal Bournissen admits luck was on her side, but her win in a World Cup super-giant slalom could provide just the boost the regrouping Swiss women's ski team needs.

Bournissen, whose only previous win came in a 1987 downhill, snatched victory from overall leader Petra Kronberger in Sunday's race, benefitting from an increasingly icy and fast course.

The No. 32 starter, Bournissen overtook the defending cup champion from Austria and won with a time of 1 minute, 20.40 seconds.

Kronberger, finishing .64 seconds behind, widened her World Cup lead despite losing her bid for a fourth victory in five races this season.
