Filip Hronek put Vancouver ahead 2-1 at 10:46 with a wrist shot from near the blue line that deflected off an Anaheim stick and fluttered over a screened Dostal.
Boeser made it 3-1 on the power play at 11:32 when he deflected a shot pass from Hughes over Dostal’s shoulder from the slot.
“Me and Quinn have connected a lot on that high tip play, so I came from the goal line and snuck in the middle, and he had some time up there,” Boeser said. “I knew Quinn would get me the puck there.”
Conor Garland extended it to 4-1 on the man-advantage at 13:25 by converting the rebound of a Hughes shot. Vancouver finished 2-for-2 on the power play.
“We started out really well,” Anaheim coach Greg Cronin said. “We scored a goal, we had two consecutive 2-on-1s where we had a no-shot on one, and Thatcher made a good save on the second one. Then we break down on a rush arrival and it seemed to elevate their game and for the like next five or six minutes, they played on their toes. They got rewarded with penalties. They score two consecutive power-play goals and for that stretch they controlled the game.”
Dakota Joshua then made it 5-1 at 14:10. He scored from close range after a deflected shot bounced onto his stick.
Anaheim called a timeout after the fifth goal.
“That wasn't Lukas' fault,” Cronin said. “Two came off our sticks, they're seeing-eye shots through traffic, and he's been our best player all year. I thought it was a moment in that timeout to rally the guys around him. He didn't deserve that. It wasn't on him, so I told them to dig in and support the goalie.”
Zegras cut it to 5-2 at 2:49 of the second period, scoring with a one-timer from below the left circle after Radko Gudas’ shot rebounded off the end boards.
Max Sasson, called up from Abbotsford of the American Hockey League earlier in the day, scored on a breakaway at 5:33 of the third period for the 6-2 final.
Cronin noted that the Ducks hit the post or crossbar four times.
“What people don't realize is we also had three pipes in the first period, three dead on pipes,” Cronin said. “I know it's a different game when you're down 5-1, but we had a lot of scoring chances to get it back to 5-3 but we just couldn't do it."
NOTES: Terry became the fourth Ducks player with 20 goals this season, joining Leo Carlsson, Mason McTavish and Frank Vatrano, who each has 20. It is the seventh time in Anaheim history that it has had four or more 20-goal scorers. … Ville Husso backed up Dostal after John Gibson sustained a lower-body injury in the second period of a 4-1 loss at the Calgary Flames on Thursday, and Ducks defenseman Jacob Trouba was a late scratch with a lower-body injury. There was no timeline for either injury. … Hughes has 12 points (two goals, 10 assists) in his past 12 games. … Boeser has 10 points (seven goals, three assists) in his past nine games.
