In the women’s round-robin Canada started strongly in the first match of their defence opening a 5-0 lead after two ends against Scotland.

After scoring in the next three ends, Scotland led 6-5 at the halfway point, and maintained the advantage throughout the second half of the match to win 9-7.

In the day’s other matches Japan beat Korea 9-6, Latvia defeated the US 10-6, Sweden beat Switzerland 7-3 and Norway defeated Denmark 9-6.
