The 22-year-old's feat was even more impressive as he lost one of his ski poles in the final with Switzerland's Carlo Janka, the giant slalom Olympic champion at Vancouver in 2010.
Held over several rounds with two skiers racing against each other simultaneously on a shortened course, one of the early victims was five-time overall World Cup champion Marcel Hirscher.
The Austrian, who won Sunday's giant slalom, was eliminated when he finished second best to Frenchman Steve Missillier.
Kjetil Jansrud's third-place finish, the Norwegian beating compatriot Leif Kristian Haugen, saw him close the gap on overall World Cup leader Hirscher to 171 points.
