Canada's Kelsey Rocque defeated the United States 8-4 to move into a first-place tie in the women's division at the world junior curling championships.

Canada (5-2) is tied with Korea, Switzerland and Russia for top spot.

Rocque's rink from Edmonton led the Americans 6-4 after eight ends and scored two in the ninth to cement its third straight win.

Canada finished the round-robin Sunday with games against Scotland (2-5) and Denmark (0-7).

In men's action, Winnipeg's Braden Calvert earned two wins, including a 6-5 decision over previously unbeaten Norway.

"I guess we'll take the win after a game like that," said Calvert. "We got off to a bad start. I threw a really bad rock in five and we had to come back from that.

"Luckily, we did and we pulled through."

Canada gave up consecutive steals to tail 3-0 at the break. But Calvert's rink rallied in the sixth as she made a tricky angle-raise double to score two.

He followed that up with a steal of two in the seventh to go ahead.

"That was huge in terms of the momentum we got from that shot," Calvert said of the sixth. "We gained a lot of confidence and basically got back at them."

Canada also beat Switzerland 7-2 to improve its record to 4-3, leaving it in a three-way tie for third.

"We're starting to get on a bit of a roll," said Calvert. "We're starting to gain some momentum and confidence.

"We were really sharp out of the gate tonight and grabbed an early deuce. That was definitely the turning point in the game and we kept fighting and were able to pull it off. All the teams here are tough and each game is going to be a battle."

Canada finishes the round-robin Sunday with games against the United States (2-5) and Austria (3-4).
