Nova Scotia's Mary Fay guaranteed at least one more match and a shot at the Canadian junior curling championships final on home ice.

Fay, who skips from nearby Chester, N.S., fell behind 3-0 on Thursday before rallying past Saskatchewan's Kristen Streifel 7-6 in Liverpool, N.S.

The win clinches a tiebreaker berth for Fay, third Jenn Smith, second Karlee Burgess and lead Janique LeBlanc, who'll play Ontario's Molly Greenwood on Friday for a spot in Saturday's semifinal.

"We're not satisfied," said Fay (7-2). "We're going to keep fighting, for sure, because we want to do the best we possibly can. And we know we can be right there."

Alberta's Kelsey Rocque (9-1) clinched a bye to Saturday's final by beating Manitoba's Meaghan Brezden 6-4, while B.C.'s Kalia Van Osch (8-2) will play either Fay or Greenwood in the semi.

"Being the first time for us to come to nationals, and doing so well, it's definitely a really good feeling," said Fay. "But we knew we could compete with these teams. I just know I have the best teammates, and we work so hard. I know that every time we go onto the ice, we can make the shots to compete with these teams.

"I don't know how much I expected, but I expected to do well and we're really pleased with how it's going so far."

Meanwhile, the Yukon's Sarah Koltun stole one in the 11th end for a 9-8 win over Northern Ontario's Krysta Burns.

In men's seeding-round games, the Yukon's Joe Wallingham was a 6-5 winner over Newfoundland and Labrador's Stephen Trickett, while Quebec's Adam Freilich turned back the Northwest Territories' Matthew Miller 10-3.
