But the 23-year-old Frostad pulled out another flawlessly executed effort to secure his first gold medal in his second Games. Norway's Tormod Frostad won his first Olympic gold in his second appearance, outdueling Mac Forehand of the United States in the men's big air final at Livigno Snow Park on Tuesday. He won gold in slopestyle last week. Forehand's silver was just the second medal for the U.S. in the freeski and snowboarding park events (big air, halfpipe and slopestyle). A snowstorm earlier in the day forced the women's snowboarding slopestyle final to be pushed back to Wednesday.
