PITTSBURGH -- Brock Boeser has found his inner chill. It's working wonders.

"I've learned that if your confidence gets too high, you won't produce and stuff like that. So I like to stay even keel, have the same approach every game," Boeser said Wednesday night after he scored twice to keep his hot streak alive and help the Vancouver Canucks down the Pittsburgh Penguins 5-2 at PPG Paints Arena.

"I think about some of the things I have to be better at and fix those, and continue to improve my game."

Boeser, who leads the Canucks with 21 points, has six goals and seven points in five-game point streak. He scored two goals for the second straight game.

"There's a lot to be excited about with Brock," Canucks coach Travis Green said of the 20-year-old, who has played just 28 NHL games. "He's playing well offensively. I'm happy with that part, but I'm really happy with the rest of his game."

Defenseman Derrick Pouliot, a 2012 Penguins first-round draft pick who never panned out with Pittsburgh and was traded earlier this season, scored the winner on a power play at 7:08 of the second for a 3-1 lead.

Loui Eriksson and Brandon Sutter also scored for Vancouver (11-8-3), which improved to 8-3-0 on the road, and goaltender Anders Nilsson made 43 saves. Michael Del Zotto and Thomas Vanek each had two assists.

Jake Guentzel scored twice and Phil Kessel had two assists for Pittsburgh (11-9-3), which lost in regulation for the second home game in a row after starting 6-0-1 at PPG Paints Arena.

Matt Murray stopped 32 Canucks shots.

Vancouver took a 1-0 lead at 3:52 of the first on a wrist shot by Boeser from the inner edge of the right circle after he got a perfect saucer pass from Sven Baertschi.

On a Penguins power play, Kessel sprang Guentzel down the slot. Guentzel got around defenseman Erik Gudbranson for a clear shot on Nilsson, who stopped an initial shot, but Guentzel swatted the short rebound inside the left post to tie it 1-1 at 6:28 of the first.

The Canucks regained the lead, 2-1, on a fluke play. Sidney Crosby's stick broke in his own end, and the puck glanced off the shaft lying on the ice and went right to Vanek. He drove to the net but was stopped by Murray before Eriksson scored on the rebound at 8:33 of the first.

Pouliot upped the lead to 3-1 with a power-play goal, and his first goal with the Canucks, at 7:08 of the second. His wrist shot from the left circle went far side and caromed in off the shin of Pittsburgh defenseman Brian Dumoulin.

"It was a great game," Pouliot said. "I was very excited to come back here and play. Both teams played really well. They came at us hard and we answered. So, it was an awesome game to be a part of."

Boeser struck again at 9:47 of the second, another Canucks power-play goal, for a 4-1 lead. He roofed a one-timer from the top of the left circle over Murray's glove.

"Me being a shooter, I like to get pucks to the net," Boeser said. "So when that slides over, I just want to make sure I make good contact with it."

Pittsburgh has allowed two power-play goals in four of its past six games.

"The goals were just weird bounces," Murray said. "Our start could have been a whole lot better, but also pretty much all the goals they got were kind of hilarious. That one with the broken stick ... that's about as unlucky as you can get.

"You've got to look at some of those goals and just laugh."

Guentzel got his second, on a power play, 1:24 into the third to make it 4-2. After Crosby won a faceoff, a Kessel pass deflected in off of Guentzel's skate.

"We had a good push," Dumoulin said. "We had some good chances to crawl back in the game, but anytime you have to come back from three, it's tough."

Sutter, another former Penguins player, added an empty-netter with 1:20 left.
