KINGSTON, Ont. -- Team Canada's Heather Nedohin remains unbeaten at the Scotties Tournament of Hearts.

She crushed Allison Ross of Quebec 12-2 on Monday afternoon to improve to 4-0 at the national women's curling championship.

"I think we're reading the ice well and we're executing (our) shots," Nedohin said. "I think having had three close games and then having one where we were able to capitalize on our opponents' misses is always a nice feel going into the next game."

Nedohin remained in a four-way tie for first place with Manitoba's Jennifer Jones, Ontario's Rachel Homan and Saskatchewan's Jill Shumay.

Jones needed only eight ends to complete an 11-4 rout of Mary-Anne Arsenault of Nova Scotia. Homan edged B.C.'s Kelly Scott 9-8 in an extra end and Shumay shaded Alberta's Kristie Moore 7-6.

All four unbeaten rinks were set to play again Monday evening at the K-Rock Centre.

Scott, Ross and New Brunswick's Andrea Crawford were tied at 2-2 while Kerry Galusha of the Northwest Territories/Yukon was tied with Prince Edward Island's Suzanne Birt at 1-3.

Arsenault, Moore and Stacie Devereaux of Newfoundland and Labrador were winless at 0-4.

Announced attendance for Draw 6 was 2,670, less than half the arena capacity of 5,700. Round-robin play continues through Friday with the playoff games set for this weekend.
