In the morning session, they were dominant against Czech Republic, skipped by Alžběta Baudyšová, with the score ending 10-3.

It was less straightforward against Cory Christensen's United States, but a score of two in the seventh end followed by a steal of two in the eighth turned the tide in the match, with the defending champions emerging 8-7 victors to maintain their unbeaten run.

Now with three wins in hand over fifth-placed Denmark and the US, wins against the Danish side and South Korea would ensure they progress from the round-robin as one of the top two seeds.

It may be the best time for them to play Kim Eun-jung's South Korea, who lost their unbeaten streak yesterday with two defeats.

Madeleine Dupont's Denmark were the first to beat them, winning 8-7 in an extra-end with a steal, and later the prestigious Swedish team skipped by Anna Hasselborg defeated them 7-3.

Kerri Einarson's Canada moved into joint-third with South Korea as the hosts recorded a crucial 10-8 win over Sweden, who sit second second behind Switzerland.

The Americans did pick up a win in the morning session, beating the debutants Turkey, skipped by Dilşat Yıldız, 12-5 to stay in contention for the top six.

Turkey lost again in the evening to Olympic mixed doubles champion Stefania Constantini and her Italian team 9-7, meaning their winless streak extended to eight matches.

Daniela Jentsch's Germany won 7-5 against Constantini's rink, while Ikue Kitazawa's Japan thrashed Denmark 8-1 to keep the challenge for the minor qualifying places interesting.

In the evening, Czech Republic defeated Japan 7-3.

Rebecca Morrison's Scotland had to withdraw from the competition due to several COVID-19 cases in the team.
