Maroon made it 3-0 with a sizzling one-timer, recording a goal and assist in a span of 57 seconds. Leon Draisaitl was set up in the offensive zone corner, waiting for the right time for Big Rig to get into the slot. He sauced a pass to the winger, who wasted no time in getting it up and over Maxime Lagace's blocker for his fifth of the season.
Puljujarvi continued showing his competence at both sides of the ice in the second period. The young Finn blocked a shot in the Oilers zone, broke his stick, then had the wherewithal to carry the play up ice as the Edmonton bench fed him a fresh stick. He finished the night with three hits, one shot on goal and one block in 11:55 of ice time.
Rogers Place approved when Puljujarvi got to the bench, giving him a rousing applause following the shift.
Matt Benning made it 4-0 Oilers at 10:19 of the second, redirecting a Klefbom point shot past Lagace. It was his second goal and third point of the season, while Klefbom recorded his second point of the night. McDavid had the secondary apple.
Although the Oilers were up 4-0, the Golden Knights continued skating, eventually getting a goal of their own.
Pierre-Edouard Bellemare broke the goose egg at 14:41 of the second, scoring his third goal of the season. He sniped a wrist shot from the slot that beat Talbot glove side to make it 4-1.
The Oilers entered the final frame with a chance to add to their lead on the man-advantage due to a late James Neal roughing minor in the second.
And the club kept the power play perfect.
Draisaitl fed a goal-line pass through the crease to McDavid, who whacked at it while Lagace was down. The netminder's right pad somehow managed to keep it out but the puck bobbled in the crease until Deryk Engelland accidentally popped it into his own net, awarding McDavid his eighth goal of the season.
Neal replied immediately for Vegas, getting an easy tap-in from a blueline pass to him on the doorstep. The forward scored his team-leading 10th goal.
