Kyle Palmieri had two goals and an assist in leading the U.S. junior hockey team to a 6-1 win over Slovakia in a preliminary round game of the World Championships on Tuesday night in Buffalo, N.Y.

Charlie Coyle had a goal and two assists while Jack Campbell had a relatively easy night, stopping 17 shots in a game the defending gold-medal winners outshot the Slovaks 57-18.

Chris Brown, Drew Shore and Emerson Etem also scored as the Americans built a 4-0 lead on 35 shots less than 12 minutes into the second period.

The U.S. is coming off a tournament-opening 3-2 overtime win over Finland, and took over first place in the Group A pool with five points with two games left.

Tomas Jurco scored for Slovakia, which was coming off a 2-1 overtime win over Germany a day earlier.

The U.S plays Germany on Thursday, while Slovakia will take on Switzerland.

Sweden puts more pressure on Russians

Robin Lehner made 30 saves Tuesday as Sweden kept Russia winless at the world junior hockey championship with a 2-0 shutout victory.

Anton Lander and Jesper Fasth scored in the first period for the Swedes, who beat Norway 7-1 in their tournament opener.

Dmitri Shikin made 36 saves for the Russians, who dropped their second straight and face an uphill battle to qualify for the next round.

Russia lost 6-3 to Canada in the opener for both teams Sunday.

At Niagara, N.Y., with the win, the Swedes jumped into a tie with Canada atop Group B. Both teams are 2-0 with six points.

Sweden faces the Czech Republic on Thursday, while Russia will look to get on track against Norway.

Finns get first win

Joni Ortio made 15 saves as Finland picked up its first win at the world juniors with a 4-0 shutout of Switzerland.

Joonas Nattinen, Jaakko Turtiainen, Teemu Pulkkinen and Julius Junttila scored for the Finns.

Jyrki Jokipakka and Joonas Danskoi picked up two assists each.

Nattinen, a Montreal Canadiens draft pick who returned this month after three months out with a severed Achilles tendon, was named player of the game.

Nattinen opened the scoring for Finland late in the first before Turtianen made it 2-0 nothing just under five minutes into the second.

Pulkkinen put the game out of reach at 4:37 of the third, with Junttila rounding out the scoring just over three minutes later.

Finland plays Germany on Wednesday.
