The Canadian women's team is unbeaten and playoff-bound at the 2013 world senior and world mixed doubles curling championships in Fredericton, N.B.

Cathy King's Edmonton rink rolled to a 12-1 win over Austria's Veronika Huber on Thursday to clinch first place in its round-robin pool and a berth in Saturday's semifinals.

But later in the day, Canada's mixed doubles team of Robert Desjardins and Isabelle Neron of Saguenay, Que., fell 6-3 to China's Yanlong Ma and Xinna Yu to be eliminated from playoff contention.

The Canadian women were in total control from the get-go against Austria. Canada (5-0) took two in the first, then stole four in the second, three in the third, two in the fourth and one more in the fifth before Austria (3-2) broke the shutout with one in the sixth.

"We seem to be just rolling right along, and it feels good," said King. "The girls are continuing to play well, and it makes my job easier out there."

The win extended Canada's streak of women's victories at the event to 48 dating back to 2008.

Canada completes its round-robin schedule on Friday against Margie Smith of the United States (3-2).

The top two teams in each round-robin pool advance to Saturday's semifinals, with the men's and women's finals set for later in the day.

In mixed doubles play, Desjardins and Neron needed a win over China (4-4) to advance to a Friday morning tiebreaker against Russia. Instead, Canada (4-4) gave up steals of one in the first, two more in the second and stolen singles in the fifth and sixth ends.

Eight teams will contest the playoffs for the mixed doubles titles, with defending world champions Martin Rios and Nadine Lehmann of Switzerland leading the charge into the final eight with an unbeaten 8-0 record in their nine-team pool.

Meanwhile, Rob Armitage's Canadian men's team is playoff-bound after a 5-2 win over Sweden's Karl Nordlund earlier on Thursday in a battle of unbeaten teams.

Sweden finished round-robin play with an 8-1 record, while Canada improved to 7-0 with two more games to play on Friday.
