In the seventh round, Anna Hasselborg put a good guard, which Pätz in Switzerland could not handle with his last stone - 4-2 to Sweden.
Switzerland, led by skipper Silvana Tirinzoni, who played as the third woman in the order, instead of the usual fourth, moved up and took two points in the eighth round.
