No women’s teams are unbeaten at the Grand Slam of Curling Players’ Championship after the last two squads with unblemished records suffered losses on Thursday.
South Korea’s Min-Ji Kim gave up four in the eighth and final end and lost 6-3 to Switzerland’s Elena Stern.
Switzerland’s Silvana Tirinzoni, meanwhile, beat reigning Canadian champ Kerri Einarson 10-3.
Kim, Tirinzoni and Einarson are tied for first in Pool A at 2-1, while Japan’s Satsuki Fujisawa and Sweden’s Anna Hasselborg are tied for the lead in Pool B at 3-1.
In men’s play, Scotland’s Bruce Mouat leads Pool A at 4-0.
Mouat won the first of two Grand Slam events last week when he beat reigning Canadian champ Brendan Bottcher in the final of the Humpty’s Champions Cup.
Team McEwen from Winnipeg skipped by Reid Carruthers is first in Pool B at 3-1.
After play Friday, the top six women’s and men’s teams qualify for the playoffs.
