The University of Minnesota's Hudson Fasching had a goal and an assist, Jack Eichel, Auston Matthews and Sonny Milano also scored, and Brandon Halverson made 14 saves.
"I thought we played a real good hockey game," coach Mark Osiecki said. "We were a bit sloppy in the first period, but came out in the second and third periods and played much better."
Eichel plays for Boston University, Milano for the Plymouth Whalers in the Ontario Hockey League and the 17-year-old Matthews, from Scottsdale, Arizona, is a member of the U.S. National Under-18 Team. Halverson plays for Sault Ste. Marie in the OHL.
"It's a great feeling to help contribute to the team," Matthews said.

Ilja Sharipov made 47 saves for Germany, coming off a 4-0 loss to Canada on Saturday night.
"It was just a terrible effort from our team," German captain Dominik Kahun said. "If we didn't have our goalie, it would have been like 15-0 or something. We just couldn't play like yesterday."
In Group B in Toronto, Pavel Buchnevich had a goal and two assists and Igor Shestyorkin made 32 saves to help Russia beat Switzerland 7-0.
Rushan Rafikov, Vyacheslav Leshenko, Alexander Sharov, Vladislav Kamenev, Sergei Tolchinski Alexander Dergachyov also scored for Russia, second in the group with five points after opening with a shootout victory over Denmark on Friday. Sweden tops the group with six points with two regulation wins.

"He can feel his legs, he's all right," Swiss captain Yannick Rathgeb said. "He can feel everything. He just didn't have any power to get up and his neck really hurt."
Switzerland was coming off an opening 5-2 victory over the Czech Republic on Saturday.
The top two teams in each group will advance to the quarterfinals.
