Snowboarder Red Gerard, a 17-year-old from Colorado, was sitting in last place heading into the third and final run Sunday in men's slopestyle.
Like many riders, he had struggled to land a clean run on his first two attempts. But when the pressure was on, he delivered.
With a brilliant third run, he locked up a gold medal, the first U.S. medal of the 2018 Olympic Winter Games.
His teammates took to Twitter to help him celebrate.
"CONGRATS @RedmondGerard!!! Snowboard slope gold for USA! You're a boss!," wrote skier Gus Kenworthy.
