The Sabres' top pick in 2011, Joel Armia, did not point for Finland for the second straight game after scoring a goal in their opener versus Team Blue.
Nic Kerdiles scored the game winning goal late in third. Stefan Matteau, Sean Kuraly, John Gaudreau, and Stefan Noesen added the other American marks. Miro Aaltonen paced the Finns with a pair of goals.
Team USA will return to action Thursday against Team Sweden. Finland gets another crack at Sweden on Friday.
