American Sage Kotsenburg won the first gold medal at the Winter Olympics in Sochi, Russia, outshining Canada's Mark McMorris and Sweden's Sven Thorgren Saturday in the inaugural men's snowboard slopestyle event.

The 20-year-old from Park City, Utah, posted his gold-medal-winning score of 93.50 on the first run of the final, while Norway's Ståle Sandbech and McMorris took the silver and bronze with scores of 91.75 and 88.75, respectively, in the second run.

Only the snowboarders' best score in the two runs of the final stage was taken into consideration.

Twelve snowboarders took part in the final, eight of whom earned their berths in the qualification stage; the other four, including Kotsenburg and McMorris, had to secure their spots in the semifinal round.

Thorgren finished fourth, while another of the favorites, Canada's Maxence Parrot, who had posted a competition-high score of 97.50 in the qualification round, finished fifth with a score of 87.25 in the final. EFE
