Vladimir Tkachyov scored the winning goal in the third period as Russia held on to beat the United States 2-1 on Friday at the 2013 IIHF World Junior Hockey Championship in Ufa, Russia.

Tkachyov scored 4:10 into the third as he put the puck past American goalie John Gibson following a terrific end-to-end rush by Valeri Nichushkin.

Forward Kirill Kapustin put Russia's lead in peril when he was given a minor penalty and 10-minute miscoSnduct for checking from behind with 1:32 left in regulation. But The U.S. was unable to beat goaltender Andrei Makarov during the late power play.

Albert Yarullin had Russia's other goal on a power play. Defenceman Jacob Trouba replied for the U.S. (1-0-0-1) with a goal on a man advantage.

Makarov, who plays for the Western Hockey League's Saskatoon Blades, was outstanding, making 41 saves.

Gibson stopped 28 shots for the Americans.

Sweden 3, Switzerland 2 (SO)

Victor Rask had the lone goal of the shootout to earn Sweden a 3-2 win over Switzerland at the world junior hockey championship Friday.

Sweden (2-0) moved atop Pool A with five points, one point ahead of Switzerland (1-1).

Swedish coach Roger Ronnberg made an interesting decision heading into the shootout by changing his goaltenders. Joel Lassinantti had played regulation and overtime but was on the bench in favour of Niklas Lundstrom for the shootout.

The move paid off as Lundstrom stopped all three Swiss penalty shots that he faced.

Sebastian Collberg and Emil Djuse scored in regulation for the Swedes, with Djuse's goal in the third forcing overtime.

Eliot Antonietii and Mike Kunzle replied for Switzerland.

Czech Republic 3, Finland 1

Tomas Hyka and Marek Hrbas scored first-period goals to lead the Czech Republic to a 3-1 win over Finland at the world junior hockey tournament Friday.

Dmitrij Jaskin added an empty-net goal for the Czech Republic (1-1).

Teuvo Teravainen had the lone goal for Finland (1-1).

The win by the Czech Republic tightened up the standings in Pool A.

Sweden leads the way with five points, with Switzerland second with four. Finland and the Czech Republic are tied for third with three points while Latvia is last with none.

Hyka opened the scoring at 14:16 with a shot over the glove of Finnish goalie Joonas Korpisalo. Less than three minutes later, Hrbas made it 2-0 after deflecting Petr Sidlik's point show on the power play.
