A stirring comeback from the Russian duo Maria Komarova and Daniil Goriachev sealed victory over PyeongChang silver-medallists Jenny Perret and Martin Rios in their opening mixed doubles fixture at the Curling World Cup Grand Final.
Trailing 5-1 heading into the sixth, Komarova and Goriachev notched four points to level the scores, before prevailing dramatically in a shoot-out to start the Beijing tournament in perfect fashion.
United States pair Sarah Anderson and Korey Dropkin ensured that it was double defeat for Swiss curlers as they toppled Michele Jaeggi and Sven Michel 8-5.
With just a point advantage heading into the eighth, the Americans held their nerve to grab two on the button and seal the win, much to the delight of Dropkin.
“It's an amazing start," he said.
“We're here to win. Obviously, we want to have fun and play our best. We've got our first win – now it's time for the second."
Elsewhere, Laura Walker and Kirk Muyres beat Chinese duo Cao Chang and Yuan Mingjie 7-3, while Canadian compatriots Kadriana Sahaidak and Colton Lott fell 6-5 to Norwegian team Kristin Skaslien and Magnus Nedregotten.
