The United States had a huge four-minute power play opportunity midway through the second period, but Malcolm Subban and the Canadian defense continued their fine work to keep the Americans off the board and preserve their 2-0 lead.
The USA had eight shots on goal during the high sticking double minor to Griffin Reinhart, but many of them were from the outside or an otherwise unchallenging angle. That's the story of the entire second period. It was a much better period for the United States, who rebounded defensively and held possession for most of the middle 20 minutes, outshooting Canada 15-8 in the period. But their chances were mostly benign thanks to a Canadian defense which held them to the outside and limited the threat.
The Americans haven't been able to pick up solid second-chance opportunities and haven't been able to get bodies in front of Subban's crease. They'll have to do that if they have any chance of putting two pucks in the net during the third period, but with the way Canada is controlling the entire ice between the dots, it won't be an easy task.
