Getzlaf scored the tiebreaking goal on a two-man advantage with 7:34 left, sending the Ducks to a 2-1 victory over the Vancouver Canucks on Thursday night.
It was the second straight game-winner for Getzlaf, who capped a stunning comeback Tuesday in Edmonton by scoring in overtime after the Ducks tied that one with 17 seconds to go in the third period.
"It's good to get rolling a little bit and find that groove and contribute like I can in the third period like that," said Getzlaf, who had just one goal in eight games before scoring in each of the last three. "Obviously, I have to contribute as much offensively as I can and power play is a big part of my game -- and that's where I get a lot of my minutes and I have to capitalize."
"That's what the new NHL is all about -- you need your power play to get some big goals," said Giguere, who earned his NHL-best 15th win.
Rookie defenseman Alexander Edler tied the score 8:22 into the third period for the Canucks, who gave the goal right back by taking three straight penalties.
The third, to goalie Roberto Luongo for clearing the puck over the glass, gave the Ducks a 5-on-3 power play. Getzlaf parked himself in the slot and one-timed Scott Niedermayer's pass from behind the net past Luongo's blocker.
"Niedermayer makes an unbelievable play there and a nice pass through the lane and I'm able to tee off," said Getzlaf, whose 11 goals are three shy of his total as a rookie last season.
Luongo made 28 saves for the Canucks, who have one win and three goals in their last four games.
Pulled after giving up three goals on nine shots when Anaheim blew out Vancouver 6-0 three weeks earlier, Luongo didn't look good when McDonald beat him under the glove on the far side from a sharp angle midway through the first period. And Luongo's errant clearing attempt cost his team on the winning goal, but he kept the Canucks in the game with several brilliant glove saves.
"As I went to shoot, the puck rolled," he said about the costly penalty. "There's no way I could get it that high normally. It's a tough break, especially after a big goal to tie it up there."
Edler's first NHL goal broke up Giguere's shutout bid. The 20-year-old slapped a rolling puck at the point through Daniel Sedin's screen in the slot and over Giguere's shoulder. But the Canucks continued to put Anaheim's second-ranked power play to work.
First, Matt Cooke was whistled for holding the stick in the offensive zone, then Kevin Bieksa was called for slashing when he chopped Dustin Penner's stick in half, and finally Luongo misplayed the puck out of play.
"It was good to settle it down and get a goal on that 5-on-3," Niedermayer said. "You need to be able to score on your power play to win games these days. Our PK had two chances to kill and did, and we scored on the power play to win it."
Giguere was good -- and lucky -- at the other end.
The Canucks buzzed early, but Sedin hit the post in the opening minute and Taylor Pyatt rang a shot off the crossbar 30 seconds after McDonald scored.
Giguere poke-checked Markus Naslund alone in tight to take away a great scoring chance late in the first and made a terrific sliding stop on Sedin's redirection after Vancouver got its first power play with 7 minutes left in the second.
"We took too many penalties," Naslund said. "You watch a good team like Anaheim and they're so disciplined and it's not a fluke they only took two penalties."
