Luongo extended his winning streak against Washington to 10 games by making 27 saves Friday night, and Taylor Pyatt scored twice, leading the Canucks to a 3-2 victory over the Capitals.
Daniel Sedin scored the other goal for Vancouver, which snapped a two-game losing streak and improved to 4-2 on the road. It wasn't easy, though, because Alex Ovechkin scored on a power play with about 1 minutes left to draw Washington within a goal, and then another penalty gave Washington a man-advantage for the final 77 seconds.
But Luongo was up to the task, making a close-range save on Michael Nylander in the final seconds.
CANADIENS 7, HURRICANES 4
In Raleigh, N.C., Tomas Plekanec had two goals and two assists to lead Montreal.
Montreal scored five power-play goals, four in the first period, en route to its third consecutive victory. The Canadiens have scored eight of their NHL-best 16 power-play goals in two games in Carolina, both wins.
Plekanec scored Montreal's first goal with the man-advantage at 8:40 in the first, and assisted on Alex Kovalev and Mark Streit's power-play goals in the period.
Kyle Chipchura, Saku Koivu and Mathieu Dandenault also scored, and Andrei Markov added three assists for Montreal, which has 17 goals in its last three games.
SABRES 4, PANTHERS 2
In Sunrise, Fla., Drew Stafford's fluke goal with 8:48 left in the third period snapped a tie and helped Buffalo break a three-game losing streak.
Stafford scored when his wrist shot bounced off goalie Tomas Vokoun's blocker high into the air, then fell in behind Vokoun. Buffalo's Daniel Paille looked as though he might have tipped the puck, but the goal was awarded after video review.
Ales Kotalik, Jochen Hecht and Paille also scored for the Sabres in their first victory on the road after an 0-3 start. Jason Pominville had two assists.
RED WINGS 5, SHARKS 1
In Detroit, Valtteri Filppula and Tomas Holmstrom each had a goal and an assist for Detroit.
Andreas Lilja, Henrik Zetterberg and Kirk Maltby also scored in Detroit's fourth win in a row. Chris Osgood made 10 saves, allowing only Alexei Semenov's late power-play goal.
Sharks goalie Evgeni Nabokov stopped 26 shots before being pulled in the third period.
