Team USA stunned Canada with five goals in the first 5:30, forced a goaltending change and romped to a 9-2 victory in the first round of the women's hockey world championships in Burlington, Vt.
It was the most goals Canada has surrendered in a women's hockey game.
Monique Lamoureux-Kolls had three goals and three assists while her sister, Jocelyne Lamoureux, had two goals and an assist. The sisters are former Gophers who transferred to North Dakota. Kelli Stack, their linemate, had three assists.
"We had a great start to the tournament tonight, but now we have to build on that," Lamoureux-Kolls said.
Jocelyne Lamoureux got things started just 37 seconds in, jamming away at the puck in the crease and past Charline Labonte. Less than a minute later, Hilary Knight knocked in a loose puck after Labonte had failed to control a shot from Kendall Coyne. Two minutes later came a power-play goal from Lamoureux-Kolls, followed by Labonte's substitution. She skated to the bench without being prompted, but when Shannon Szabados came in, little changed.
The United States will play Russia on Sunday, and Canada will play Finland.
