GLENDALE Ariz. -- After dominating for most of the first 48 minutes, the Boston Bruins suddenly found themselves stuck in a tie game with the Arizona Coyotes midway through the third period and in need of a second wind to get over the hump.
Patrice Bergeron and the Bruins' power play did the job.
Bergeron deflected home Ryan Spooner's power-play shot with 10:50 left to put Boston ahead to stay and added another extra-man goal with 1:06 left to help the Bruins defeat the Coyotes 5-3 at Gila River Arena on Saturday.
Center David Krejci continued his hot start with a goal and two assists to help the Bruins beat the pesky Coyotes for the seventh straight time. They outshot the Coyotes 43-23 and have won back-to-back games after a 0-3-0 start.
"[The power play] is moving the puck very well and we're talking what's open," said Bergeron, who also had an assist on Brad Marchand's shorthanded goal earlier in the third period. "We're not trying to force it. Up top, guys are finding a way to get pucks on the net and we're trying to collapse and find it. We have to keep doing more of that.
"We showed a lot character all night, first to find a way to get the lead and then to get it back."
Krejci has four goals in five games and is tied for the NHL lead with nine points. He set up rookie Tyler Rendell for his second goal in as many games 8:42 into the second period to make it 1-1, then scored Boston's first of three power-play goals at 15:19 to give the Bruins their first lead.
"You're disappointed if you don't score on the power play. If you don't expect to score, you shouldn't be out there," Krejci said. "It's been good [to get off to a good start], but it's better the last few games because now we're winning."
Captain Shane Doan had a goal and two assists for Arizona, moving him past the 900-point mark in the process. He trails Dale Hawerchuk by 10 goals and 27 points for the all-time franchise record in each category.
The Coyotes have followed a 3-0-0 start with consecutive home losses. Arizona goalie Mike Smith made 38 saves but was unable to hold off the relentless Bruins.
"They outplayed us in the first half of that game pretty badly. [Mike Smith] was unbelievable. We deserved to be in a bigger hole than we were going into the third," said Doan, whose team entered the final period down 2-1 despite having been outshot 33-10. "We've got to find ways to win games at home. We didn't think we started the way we needed to, and that can't be a trend."
The Coyotes were outshot 19-4 in the second period and trailed 3-1 early in the third after Marchand snuck behind Arizona's defensemen during a power play. He took a Tommy Cross pass off the boards and beat Smith on a shorthanded breakaway for a 3-1 lead.
"They were trying to keep the puck in and I was hoping it got through," said Marchand, back in the lineup after missing two games with a concussion. "Lucky it did: Otherwise I would have been in trouble."
But the Bruins were in trouble a few minutes later. With Boston defenseman Adam McQuaid still in the box, Tobias Rieder got the goal back for Arizona 13 seconds later, scoring for the third time in five games. Kyle Chipchura got the Coyotes even at 7:21, burying a Doan feed behind Boston goalie Tuukka Rask to tie the game 3-3.
"I didn't have a lot shots but when I had them they were pretty tough," said Rask, who made 20 saves for his first win of the season, "When we got up 3-1 we kind of let down a little bit and they really gave us everything. But we managed that and the power play was great tonight."
The tie lasted less than two minutes before Bergeron put Boston back in front.
The Bruins finished 3-for-6 with the extra man and are 7-for-18 this season. They scored three times in two of their past three games.
"They seem to be reading off each other well and know where they want to go," Boston coach Claude Julien said. "They've got confidence right now and every one of them has poise with the puck."
The Coyotes lost forward Joe Vitale after he took several shots to the face during a fight with Boston's Kevan Miller in the second period. He went to the hospital for X-rays after the game.
