Russia's Vic Wild won Winter Olympic gold in the men's snowboard parallel giant slalom, defeating Switzerland's Nevin Galmarini in the final.
Wild, who used to compete for America, earlier saw his wife - Alena Zavarzina - win bronze in the women's final.
Slovenian Zan Kosir pipped German Patrick Bussler to the bronze.
Defending Winter Olympic champion Jasey Jay Anderson went out in the early stages of the competition, failing to make the quarter-finals.
Benjamin Karl, who won silver in Vancouver four years ago, went out at the same stage as Anderson.
