"I feel honored to be in the same category as Tanner but couldn't be more honored to be here with my homies," Goepper said, specifically shouting out to competitors McRae Williams and Andreas Håtveit, the silver and bronze medalists, respectively. "It's Andreas' last time here, so it couldn't have been a better day."
Håtveit, who will compete in Sochi with the Norwegian Olympic team, has announced this will be his last competitive season.
On his second run, Gus Kenworthy landed a switch triple rodeo 1440, the first triple cork landed in an X Games Ski Slopestyle competition. Goepper brought the second -- a rightside triple cork 1440 in his second run -- to bump into second place and landed it again in an even cleaner third run, improving to 95, the highest score of the day.
Goepper, who broke two bones in his left hand this past fall, skied his run with a wrist brace and no poles.
He was the first to qualify for the U.S. Freeskiing Olympic team and will lead the charge as the team heads to Sochi for freeskiing's Olympic debut.
"It's going to be crazy," he said. "Definitely keep your eyes open and wake up at 2 in the morning to watch the show."
Henrik Harlaut, the Ski Big Air gold medalist from Saturday night, just missed the Slopestyle podium, finishing in fourth.
