Canmore's John Morris and Winnipeg's Kaitlyn Lawes are on a roll at the Gangneung Curling Centre in PyeongChang, Korea. After losing their opening round-robin match to Norway, the Canadians have reeled off four straight wins in Olympics mixed doubles, with the last being a 7-2 six end victory over the defending world champions from Switzerland, Friday (Feb. 9). In a game where Swiss curlers Jenny Perret and Martin Rios stole a point in the first end, but never really got on track, particularly with their draw game, the Canadians took advantage of several second end Swiss misses before Lawes played a light hit and roll with her last shot for four points and a 4-1 lead. The teams traded singles in the third and fourth ends and Canada stole one in the fifth to led 6-2. With two Swiss rocks sitting back of the button, Lawes had coolly drawn to the button and the Swiss, realizing they could not remove her rock, simply threw their last away. In the sixth end, Perret's final shot for the Swiss was a hit, but she was light, moving one of their own stones off the button for another Canadian steal and handshakes after a 7-2 win. Morris and Lawes take on OAR (also 4-1), Saturday (Feb. 10). Prior to the win, there was some controversy involving the Canadians in the draw to the button that decides hammer. Errors were made in measuring who was closest to the pin, due to new technology, and the Canadians, Swiss and other teams waited long minutes for the error to be addressed. "They have a new system and it measures to the centre of the rock. It's a complicated process now and it's prone to potential error," said Morris post game on CBC. "It's important and a team can be eliminated by LSD (last shot draw) so everyone's life is on the line and it was unfortunate because it made a lot of other teams wait and I don't think it's fair for anyone out there. "We just want to make sure we get valid results for every team out here." A re-measure was done, because collectively, distances from the pin in the draw to the button may be used later to break ties in scoring.
