The United States beat the Czech Republic 3-0 on Thursday to set up a semifinal game against Germany at the ice hockey world championship.
Canada will face Latvia at Nokia Arena in the other semifinal on Saturday.
The Americans earned their eighth straight victory.
“This was a tough game and I’m really proud of our team and how we stuck to our game plan,” U.S. head coach David Quinn said. “There’s a real selflessness to our team and that’s been evident from the outset.”
Matt Coronato scored on a shot from the left circle that deflected off the skate of a Czech defenseman and into the net in the opening period in which the Czechs managed just two shots on goal.
Nick Perbix doubled the advantage midway through the second with a shot into the roof of the net to beat goaltender Karel Vejmelka.
