Pacioretty came out of the penalty box to score his second of the game for a 4-1 lead at 8:12. Pacioretty, out five weeks with a lower-body injury before returning Nov. 24, has scored five goals in six games.
"We did a good job of playing fast, moving the puck quick in transition. When we're able to do that, it's a huge game-changer," Vegas defenseman Nicolas Hague said. "It gives us confidence when we can move it up quickly, stay out of the D-zone and play in the offensive zone."
Amadio scored his first goal since Dec. 14, 2019 for a 5-1 lead at 12:47. Dylan Coghlan stole the puck to set up Dadonov's goal at 15:08 to make it 6-1 and Roy scored at 17:54 of the third for the 7-1 final.
"It's frustrating," Coyotes coach Andre Tourigny said. "We take a lot of pride in being tough to play against, you've got to work hard against us. But when you get beat up the ice, when you give us odd-man rushes, it's a dream for an offensive player."
