Kyle Mack styled his way to a silver medal.
The first-time Olympian landed a frontside triple cork 1440 bloody Dracula, a stylish trick he was the first to land, to help him earn his medal in big air snowboarding at the Alpensia Ski Jumping Centre on Saturday.
Mack took a surprise medal in an event the Canadians were favored to sweep.
Sebastien Toutant of Canada took gold, Billy Morgan of Great Britain claimed bronze. Chris Corning and Red Gerard, the gold medalist in slopestyle, finished fourth and fifth.
Ivanka Trump, who is heading the U.S. delegation for the closing ceremony, was in attendance.
The big air event, where riders complete two tricks and the total score determines a winner, was a new addition to the Olympic program this year.
