OTTAWA -- University of Minnesota freshman Jordan Schroeder had two goals and an assist to help the United States beat the Czech Republic 4-3 on Sunday night in the world junior hockey championship.
Schroeder, eligible for the 2009 NHL draft, leads the United States (2-0) in scoring with three goals and four assists.
"I'm focused on winning," Schroeder said. "I'm glad we got the win today and it was big for the round robin. If we would have lost that game, it could have been a different story."
New Hampshire's James van Riemsdyk, the second overall pick in the 2007 draft by Philadelphia, added a goal and an assist. Michigan's Matt Rust also scored, and Thomas McCollum, who plays for the Ontario Hockey League's Guelph Storm, made 24 saves.
"Playing with van Riemsdyk and [Colin] Wilson, I knew we'd have a big impact in the tournament," Schroeder said. "They're great players, fun to play with and they make plays,"
Ondrej Roman, Martin Paryzek and Jan Kana scored for the Czech Republic (0-2), coming off an 8-1 loss to Canada in its opener.
The United States, a 8-2 winner over Germany on Friday night, will face Kazakhstan (0-2) on Tuesday night, and conclude Pool A play Wednesday night against four-time defending champion Canada (2-0).
"Right now we're focused on Kazakhstan, but it will be fun when we get there," Schroeder said.
The two pool winners will earn byes to the semifinals.
Earlier at Scotiabank Place, Jamie Benn scored three goals, and John Tavares and Cody Hodgson each had two goals and two assists in Canada's 15-0 win over Kazakhstan.
"It's a nice feeling and I'm happy about it, but it's one of those games where you can't get too excited," said Benn, a Dallas draft pick.
Defenseman P.K. Subban also scored twice, Tyler Ennis had a goal and two assists, and Jordan Eberle, Chris DiDomenico, Evander Kane, Stefan Della Rovere and defenseman Tyler Myers added goals. Chet Pickard made 11 saves for the shutout in his first start of the tournament, while four-time defending champion Canada had 69 shots on goals.
"On our team, there's not enough talent," Kazak defenseman Evgeni Bolyakin said. "We need more practice. We just don't have enough skill."
It was one of the Canada's most lopsided victories in the tournament. Canada beat Germany 18-2 in 1985 and routed France 15-0 in 2001.
With goal differential a part of the tiebreaking formula at the conclusion of the preliminary round, the Canadians ran it up against their overmatched opponent.
"With goal differential that could come upon us later in the tournament, it was very important for us to get as many goals as we can and keep the pucks out of our net," Subban said. "The good thing is, we don't have time to dwell on it. We turn around tomorrow and we're back into it again."
Canada (2-0) will face Germany (1-1) on Monday.
At the Ottawa Civic Centre, Russia and Sweden improved to 2-0 in Pool B. Russia beat Finland 5-2, and Sweden topped Slovakia 3-1. Slovakia is 1-1, and Finland 0-2.
Nikita Filatov, on loan from the Columbus Blue Jackets, and Dmitri Klopov each scored two goals for Russia, and linemate Evgeni Dadonov had a goal and two assists.
Jacob Markstrom made 26 saves for Sweden, and Simon Hjalmarsson, Mikael Backlund and Erik Karlsson scored goals.
