Canada's Kerri Einarson defeated Italy's Stefania Constantini 7-2 in round-robin play at the world women's curling championship.
Einarson, Val Sweeting, Shannon Birchard and Briane Harris improved to 3-1 after six draws of play at the Goransson Arena.
Italy faced a triple-raise double-takeout to score in the ninth end but gave up a steal of two to end the game.
Einarson and her Manitoba-based team will play Scotland's Rebecca Morrison later Monday.
The top six teams in the 13-team field will qualify for the playoff round. The final is scheduled for Sunday.
Einarson won bronze at last year's world championship in Prince George, B.C.
