Russia beat the United States 5-3 in the world junior hockey quarter-finals Thursday in Sweden, rallying to take the lead on Nakita Zadorov's two power-play goals.

Zadorov scored on 5-on-3 advantages in a 1:01 span in the second period to give Russia a 4-3 lead. The 6-foot-4 defenceman plays for the London Knights in the Ontario Hockey League.

Russia will face Sweden in the semifinals. Canada and Finland will meet in the other semi after winning their quarter-final games on Thursday.

"We want to play Sweden," Zadorov said. "It was a close game last time [3-2 loss], and we're going to watch some video and play better."

Pavel Buchnevich also scored twice for Russia, Buffalo Sabres center Mikhail Grigorenko added a goal, and Andrei Vasilevski made 30 saves.

"The power plays were the game-changer," said Grigorenko, who has two goals and an assist in 18 games for Buffalo this season. "We scored two goals. We took the lead, and we kept it. Those two 5-on-3s in a row were the key.

"This game made us a better team today than we were yesterday. I think we deserved to win. Hopefully, we can keep the same energy, same compete level for the semifinals."

New Jersey Devils farmhand Stefan Matteau, Plymouth Whalers forward Ryan Hartman and Wisconsin's Nic Kerdiles had first-period goals for the United States, the tournament winner last year in Russia.

"Penalties," said Matteau, off for tripping when Zadorov scored the tying goal. "They buried their chances. The refs did their job. I know North American teams coming over here ... maybe the officiating is different, but we still gave them a reason to call penalties. That's what shot us in the foot. But we got power plays, too. We didn't finish."

Providence's John Gillies stopped 20 shots.

"It's not a good feeling, but I think it will make us all better players," Gillies said.
