Nikola Bubakova of the Czech Republic won the women's GS with a two-run combined time of one minute 53.47 seconds. Elvedina Muzaferija of Bosnia followed in 1:54.60 while Dufresne, fourth after the first run, reached the podium clocking 1:55.67.
''It went a lot better than expected,'' said the 15-year-old Dufresne. ''I wasn't focused as much on performance as on how I skied. The conditions were difficult and I managed it well.''
In the men's slalom, Mikkel Solbakken and Markus Fossland, both of Norway, finished one-two. Solbakken clocked a two-run combined time of 1:20.32 and Fossland finished in 1:22.57. Hiroto Hasebe of Japan was third in 1:22.70.
Asher Jordan of Whistler finished fourth. Gavin Donald of Vernon, B.C., and Adrien Grabinski of Calgary tied for fifth.
''I was very happy with my performance,'' said Jordan. ''The conditions were challenging with the wet sticky snow and I was happy to finish both my runs.''
