The Americans peppered the German net with 46 shots. Timo Pielmeier, who plays for the Quebec Major Junior Hockey League's Shawinigan Cataractes, gave up five goals on 27 shots in the first two periods.
Pielmeier was replaced by Philipp Grubauer of the Belleville Bulls to start the third. Grubauer allowed two goals on 19 shots.
Thomas McCollum of the Ontario Hockey League's Guelph Storm stopped 16 of 18 in net for the U.S.
Toni Ritter and Patrick Pohl scored for the Germans, who earned promotion to this tournament by winning one of two world 'B' junior championship earlier this year.
