"We know we have the next game", Stauber said.
It seems to go Canada's way often at the Olympics.
Canada and the United States are the only countries to ever win women's hockey gold at the Olympics. "We're going to give 100 percent".
But Thursday the rewards didn't come.
Geneviève Lacasse made 44 saves for Canada and stopped Jocelyne Lamoureux-Davidson on a penalty shot at 14:08 of the second period. Not in the second period, when Jocelyn Lamourex-Davidson was awarded a penalty shot, went forehand, backhand, forehand, backhand and then watched her shot ricochet off the knob of Lacasse's stick.More news: What to watch from Pyeongchang - Day 5
Brianna Decker hit the post on a final United States shot and a scramble in front of the Canada goal for the puck led to pushes, shoves and two roughing penalties well after the final horn. He was a member of the US squad that won bronze in 2006. We've got some awesome forwards with some poise and patience and some great shots.

Nurse then took things into her own hands and flicked a wrister into the top shelf for the second goal and additional breathing room for Lacasse.
Finland, who beat the Russians to take the third seeding, will meet sixth-seeded Sweden on Saturday for the right to play the Americans, and the fourth-seeded Russians take on fifth-seeded Switzerland to earn a spot against Canada.

"It's always a battle, especially playing the U.S.", Agosta said. "So we just gotta find a way to get those hard-nosed goals". The man credited with coming up with the concept of a hand-picked team was Father David Bauer, a Catholic priest, and brother to NHLer Bobby Bauer, who coached teams at St. Michael's College and the University of British Columbia.
