The United States beat the Czech Republic 3-0 on Thursday to set up a semi-final game against Germany at the ice hockey world championship.
Canada will face Latvia at Nokia Arena in the other semi on Saturday.
The Americans have been cruising through the tournament and 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 defenceman 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.
Cutter Gauthier completed the scoring in the third with his seventh goal at the tournament.
Casey DeSmith made 15 saves for the shutout.
The quarter-final was a repeat of last year’s bronze-medal game, which the Czechs won 8-4.
In the Latvian capital of Riga, Germany upset the favourite Switzerland 3-1 to reach the semi-finals.
Jonas Siegenthaler answered Germany’s opening goal by Maximilian Kastner before John Peterka and Nico Sturm netted for the Germans.
Also in Riga, co-host Latvia followed the suit by upsetting Sweden 3-1.
Dans Locmelis, Mick Indrasis and Janis Jaks scored for Latvia. The Latvians beat Sweden for only the second time at the world championship and gave themselves a first chance to play for a medal.
Timothy Liljegren scored for Sweden.
