"We were excited to see so many players getting involved tonight, especially our defenders, who have had a tremendous impact so far in this tournament," U.S. coach Bob Corkum said. "While we will enjoy this victory tonight, we know we have our work cut out for us as we head into the playoff round and we'll be ready for the next challenge."
