RIGA, Latvia -- Mika Hannula's hat trick helped Olympic champion Sweden beat the United States, 6-0, yesterday in the quarterfinals at the World Ice Hockey Championship.

Sweden goalie Johan Holmqvist had 18 saves, earning his first shutout in five tournament games.

The Swedes will face Canada, which scored three goals in a span of 1:39 in the third period to beat Slovakia, 4-1, in another quarterfinal. Today, Russia will face the Czech Republic and Finland plays Belarus.

The Penguins' Sidney Crosby scored one of the third-period goals for Canada. He leads the tournament with seven goals and is tied for the scoring lead (13 points) with Canadian teammate Patrice Bergeron of the Boston Bruins. Bergeron, Mike Cammalleri and Jeff Carter also scored for Canada, which will face Sweden in a semifinal Saturday.

Penguins forward Ryan Malone was named one of Team USA's top three players along with Dustin Brown of the Los Angeles Kings and Andrew Alberts of the Boston Bruins. Malone finished the tournament ranked second on Team USA in scoring with four points (two goals, two assists) in seven games.

Penguins forward Andy Hilbert finished with three assists in seven games for Team USA and defenseman Brooks Orpik went scoreless in seven games.

Evgeni Malkin, the Penguins' first-round pick in 2004, leads Russia in scoring through six games with eight points (three goals, five assists) and leads the team with a plus-5 rating.

Coming into its game against Sweden yesterday, the United States had allowed just 10 goals, tied with Finland and Slovakia for the fewest given up in the tournament.

But the Americans came out flat against Sweden, falling behind, 1-0, when Hannula scored 2:48 into the game. Hannula made it 2-0 late in the period, knocking in a rebound from close range off a shot by Niklas Kronwall, another Olympic gold medalist.

"We knew we had a tough opponent," Swedish coach Bengt-Ake Gustafsson said. "The start of the game was so important for us. We got a 2-0 lead and, after that, we thought we controlled the game pretty good.

"Luckily, we got a couple of more goals. But the win is the most important thing, and now we're looking forward to the semifinal."

Hannula completed his hat trick halfway through the third period after taking a perfect feed from Jonas Nordquist.

Mikael Samuelsson and Kenny Jonsson scored for Sweden in the second period, with Jonsson's goal coming on a power play. Andreas Karlsson notched another power-play goal to complete the scoring late in the third period.

U.S. goalie Craig Anderson was replaced by Jason Bacashihua at the start of the third period.

"We did not have our 'A' game," U.S. coach Mike Eaves said. "Part of that is because Sweden played so well. They won a lot of battles. We were just never able to get a spark and get back our game we had yesterday [against the Czechs]."

The United States had one of the youngest teams in the tournament, and the roster did not include anyone who played at the Winter Olympics.

"We had the opportunity to give a lot of young kids experience at the international level," Eaves said. "That was important for us and will pay dividends down the line."
