VANCOUVER, British Columbia - Penalty killing kept the Anaheim Ducks in the game on Sunday night. The power play won it for them.

Corey Perry scored the go-ahead goal on a power play 7:51 into the third period as the Ducks recovered from a double-overtime loss at home in Game 2 with a 3-2 victory over the Vancouver Canucks.

Perry's goal, on a screened slap shot from the top of the faceoff circle, came 70 seconds after the Ducks killed off his holding penalty, and less than five minutes after the Canucks failed to score on their second lengthy 5-on-3 of the game.

"We had to weather the storm on the penalty kill and we took a few too many tonight," said Perry, who also set up Dustin Penner's goal 3:08 into the first period.

Francois Beauchemin also scored, and Jean-Sebastien Giguere made 24 saves, including three in the final seconds, as the Ducks took a 2-1 series lead.

Special teams made the difference as the Ducks killed off seven of eight power plays and converted two of their five chances at the other end.

"We had a pretty good power play all year," Perry said. "It's a big key to our game and a big key to our team, we feed off the momentum from our power play."

For the Canucks, the power play was a momentum killer.

Just 3-for-50 in the playoffs coming into the game, Markus Naslund scored with the man advantage late in the first period. But Vancouver managed just two shots during a two-man advantage for 1:22 early in the third period, and failed to get a shot on Perry's penalty just before the winning goal.

"That was a key moment of the game, too and we needed to get a goal there," Naslund said. "We have to have better shots, hit the net and be strong on rebounds."

They didn't do any of that, and with Alexandre Burrows off for shooting the puck out of play, Perry sent a screen shot between the legs of goalie Roberto Luongo.

"He's playing well, but what he can't see he can't stop," Perry said.

Daniel Sedin also scored, and Luongo made 21 saves for the Canucks, who have already bounced back from a 5-1 loss in Game 1 and can tie the best-of-seven Western Conference semifinal series at home on Tuesday night.

"We're down a game here but we know that we can beat them and we just have to work on a few things and I think we'll be right there," Naslund said.

After winning in double overtime in Game 2, Vancouver outshot the Ducks 13-2 in the first period. But they went into the intermission tied 1-1 because of an inept power play, some great saves by Giguere and a rare mistake by Luongo.

Giguere made four great stops in the opening 2 1/2 minutes, including two tips in front and a pad stop on Jan Bulis off a rebound. But Anaheim opened the scoring on its first shot at 3:08, with Luongo playing the puck past his own defenseman and straight to Perry in the corner. He spotted Penner alone in the slot for the goal before a diving Luongo could get back into position.

"I was trying to shoot it hard and didn't get all of it and it went right on his stick," Luongo said. "It was a tough goal to give up right off the bat and unfortunately I have to take the blame for that one."

Vancouver had another great chance to score when top Ducks defensemen Scott Niedermayer and Chris Pronger took hooking penalties 1:23 apart later in the period. But the Canucks managed just one shot on the 5-on-3.

The power play finally clicked after the fourth straight Anaheim penalty, with Naslund driving hard to the net to tap in a rebound after Giguere only got part of Mattias Ohlund's hard point shot. It was Naslund's second goal in as many games.

"I think our heads are spinning still," Ducks winger Teemu Selanne said of the start. "We were talking and we wanted to be good in the first period and god, it was ugly. But the PK was the key thing tonight and the PP too."

Anaheim only needed one power play to retake the lead. Luongo got a piece of Beauchemin's deflection from the slot, but the big defenseman beat him to the rebound, knocking in the loose puck before the goalie could smother it.

Daniel Sedin tied it again four minutes later after Taylor Pyatt's wraparound came straight to him on the other side and he snapped it in off Giguere's pad.

Anaheim took three more penalties early in the third period, but it didn't matter against a Canucks power play that struggled at times to even get set up and is now just 4-for-58 in the playoffs.

"It was good to see us killing those penalties but we're playing with fire right now by taking so many," Giguere said.

Notes:@The Canucks got top D Sami Salo back after missing the first two games with a torso injury, but D Rory Fitzpatrick joined Kevin Bieksa on the injured list. Anaheim LW Brad May, who spent parts of five seasons in Vancouver, returned after serving a three-game suspension for punching Minnesota D Kim Johnsson in the first round. Tough guy George Parros came out of the lineup. Selanne didn't have a shot after recording seven in Game 2.
