Scotland stars Eve Muirhead and David Murdoch were unable to help the Rest of the World team avoid defeat at the hands of North America in the 2014 Continental Cup in Las Vegas.
World champion Muirhead, who will represent Great Britain at the upcoming Winter Olympics in Sochi, lost her women’s skins to the United States’ own Olympic contender Erika Brown 3-2.
Muirhead’s GB team-mate Murdoch also tasted defeat in the mixed skins as his team, which included compatriot Scott Andrews and Japanese duo Satsuki Fujisawa and Miyo Ichikawa, were beaten 4-1 by an all-Canadian line-up.
Those results helped North America to record a 35-25 victory over the World side to win the competition for a sixth time.
British Olympic curling coach David Hay, who coached the Rest of the World, admitted his side were below-par in the competition but does not believe the North Americans will have it all their own way in Sochi.
He said on www.teamgb.com: “We underperformed this week. We didn’t perform as well as we should have done.
“The Canadian and American teams played very well. Some of our guys played very well at times but not well enough all the way through, so they were deserved winners.
“The next event (Sochi) will be life-changing for someone. There are going to be some close contests out there and if the ice is as good as it was here there will be some outstanding games of curling.”
