With the win, the Ducks improved to 11-4-0 since a Halloween afternoon win over Montreal at Honda Center, the best record in the Western Conference and the second-best mark in the NHL over that span.
"I thought right from the start, right through the finish, we were moving our feet," head coach Dallas Eakins said. "I thought we made some great plays at the other end. As always, if pucks go in your net, it's always along the line. You're looking to try to keep those out. We made some mistakes, we didn't get squirrely on the bench, we just kept playing."
Anaheim also improved to 9-4-1 at Honda Center, tied for the most home wins among Western Conference clubs.
"Our fans here are incredible," Eakins said. "It is so loud down on that bench. I think they have had a massive effect on our home record here. Without them last year, go have a look at what our home record was. This year, with them, it's like day and night."
Troy Terry, Rickard Rakell, Josh Manson, Hampus Lindholm, Jamie Drysdale and Isac Lundestrom scored for Anaheim.
Anthony Stolarz made 34 saves to earn his third conseuctive victory.
For the second straight night, Anaheim skated to a scoreless first period thanks to an early goaltending duel. Stolarz turned aside all 13 Vegas shots he saw in the opening 20 minutes while Golden Knights netminder Robin Lehner made 11 saves on the other end of the ice.
The scoreless deadlock did not last long in the middle frame, though. After weathering a Vegas surge to start the period, Anaheim took the first lead of the night. Jamie Drysdale took a pass at the right point from Sam Steel before working his way towards the slot and spotting Terry alone on the far side of the ice. Drysdale delivered a perfect pass and Terry did the rest, one-timing a shot just inside the post to give Anaheim a 1-0 lead.
