MALMO, Sweden (AP) -- Russia beat the United States 5-3 in the world junior hockey quarterfinals Thursday, 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 defenseman plays for the London Knights in the Ontario Hockey League.
Russia will face Sweden, a 6-0 winner over Slovakia, in the semifinals Saturday. In the other quarterfinals, Canada beat Switzerland 4-1, and Finland topped the Czech Republic 5-3.
''We want to play Sweden,'' Zadorov said before the Swedes' victory. ''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.
Russia has won the under-20 event 13 times, the first nine as the Soviet Union.
Canada advanced to the semifinals for the 16th straight year. It won the last of its record 15 titles in 2009 in Ottawa, Ontario.
Anthony Mantha scored on a penalty shot, beating Marvin Nyffeler with a backhander, and Griffin Reinhart, Curtis Lazar and Derrick Pouliot added goals for Canada. Zach Fucale made 19 saves, allowing only Nico Dunner's goal with a second left in the second period.
''Our mentality is we wanted to get better every day, and that's what we've done,'' Mantha said. ''We need to continue to do that in our next game.''
Canada is 22-0-0 against Switzerland in the event and has a 130-34 scoring advantage.
''We knew it wasn't going to be an easy game,'' Canadian coach Brent Sutter said. ''All the pressure was on us. They had nothing to lose. We knew they'd play hard and we had to make sure we stuck to our game plan. Other than taking too many penalties in the third period, I thought we responded well.''
Sweden, 5-0-0 in the tournament, is seeking its third title and second in three years.
''We're getting closer - two games away,'' Colorado College defenseman Gustav Olofsson said. ''It feels more exciting and more fun to play when you get closer to gold.''
Nashville Predators winger Filip Forsberg had two goals and two assists, Lucas Wallmark also scored twice, Carolina Hurricanes center Elias Lindholm added a goal and three assists, Jacob de la Rose had a goal, and Erie Otters goalie Oscar Dansk made 18 saves.
Lindholm has three goals and four assists in 21 games this season for Carolina, and Forsberg has a goal and four assists in 12 games for Nashville.
''We have to stay out of the penalty box a little more,'' Forsberg said. ''They're pretty dangerous and it's going to be even more dangerous against Russia. That's something we have to work on.''
Finland overcame a 3-1 deficit to beat the Czech Republic, taking a 4-3 lead on Saku Kinnunen's goal with 8:21 left.
Saku Maenalanen scored twice, and Juuso Ikonen and Henri Ikonen added goals for Finland. Dominik Simon, Martin Prochazka and Radek Faksa scored for the Czech Republic.
Norway beat Germany 3-0 in Game 1 of the best-of-three relegation series. Joachim Svendsen made 29 saves, and Martin Ronnild, Didrik Svendsen and Andreas Klavestad scored.
