If what happens in Vegas stays in Vegas, the Pittsburgh Penguins are presumably eager to vacate Vegas.

Especially since wins rarely seem to happen there for them.

Skating once again without the services of superstar forwards Sidney Crosby (suspected right leg injury) and Evgeni Malkin (suspension), the Penguins were unable to keep up with the offensive firepower of the Vegas Golden Knights and were thumped, 6-2, at T-Mobile Arena in Las Vegas on Thursday.

The result was the Penguins’ fourth-consecutive loss in Sin City and dropped their all-time road record against the Golden Knights to 2-6-0 since that franchise entered the NHL in 2017.

The Penguins are 0-1-1 in the first two games of an ongoing five-game road trip.

Rookie goaltender Arturs Silovs stopped 11 of 16 shots as his record fell to 14-9-8.

Golden Knights forward Colton Sissons opened the scoring with his fifth goal of the season — and the 100th of his career — 8:41 into regulation.

Under pressure from Golden Knights forward Brett Howden, Penguins defenseman Parker Wotherspoon turned a puck over in the defensive zone along the right wing boards. Golden Knights rookie defenseman Braeden Bowman accepted the charity at the near point, cut through the slot and fed a pass from below the lower left hashmark to the front of the crease. Sissons barged in, established position above the blue paint and shoveled in a forehand shot under Silovs’ left leg. Bowman had the only assist.

The Golden Knights went up by a pair via forward Pavel Dorofeyev’s team-leading 31st goal at 5:02 of the second period.

Following a failed clearing attempt by Penguins defenseman Ilya Solovyov from the left of his own cage, Golden Knights defenseman Kaedan Korczak corralled the puck in the high slot. Suggesting he would fire a wrister for a moment, Korczak slipped a pass to the right of the crease for Dorofeyev, who roofed a near-side wrister over Silovs’ left shoulder. Korczak and Bowman bagged assists.

Penguins forward Rickard Rakell got his team on the scoreboard at 8:26 of the second frame with his 13th goal.

Off some passing around the perimeter of the offensive zone, Penguins defenseman Ryan Shea accepted the puck at the left point, then fed it toward the near corner for forward Bryan Rust. Turning to his left, Rust surveyed his options, then snapped an offering toward the far side of the crease. Golden Knights defenseman Brayden McNabb appeared to sufficiently seal off the passing lane, but Rakell was able to shimmy his stick from the right of the cage into the blue paint and direct a backhander by goaltender Adin Hill’s left skate. Rust and Shea secured assists.

Only 54 seconds later, Golden Knights forward Mitch Marner found his 19th goal.

Collecting a blocked shot in Vegas’ zone, Penguins forward Connor Dewar backtracked to the neutral zone and attempted an ill-conceived backhand toward the visiting penalty box intended for linemate Blake Lizotte. Applying light pressure, Marner easily stole the puck and generated an offensive rush. Gaining the Penguins’ zone on the right wing, Marner leveled out in the high slot, then left a drop pass for Dorofeyev after the pair crisscrossed. As Dewar spun out of orbit in trying to defend the attack, Dorofeyev quickly fed the puck back to Marner, who deked past a poke check attempt offered by Silovs and tucked in a forehand shot while sprawling to the ice. Dorofeyev was deemed worthy of the lone assist.

The Penguins persisted as rookie Ben Kindel scored his 16th goal at 16:22 of the second period.

As the Golden Knights made a line change — with the benches on the far end of the rink from each team’s defensive zone — Shea slung a stretch pass from his own left circle across the ice to the center red line for Penguins forward Anthony Mantha. Galloping into the Vegas zone on the left wing, Mantha shielded the puck from Bowman, waited for a passing lane to open and directed a backdoor feed for an onrushing Kindel, who tapped in a forehand shot over Hill’s left leg. Assists were merited by Mantha and Shea.

Dorofeyev scored again 4:35 into the third period.

Taking a pass from Wotherspoon at the right point of Vegas’ zone, Penguins rookie forward Ville Koivunen was muscled off the puck by Dorofeyev, who directed the puck into the neutral zone. Marner took possession and gained the Penguins’ zone on the left wing, creating an odd-man rush. As Penguins defenseman Erik Karlsson provided positionally sound resistance, Marner fed a pass from the lower left circle to Dorofeyev, who swiped a one-timer from between the hashmarks past Silovs’ glove. Marner had the lone assist.

Golden Knights forward Jack Eichel got in on the act at 6:20 of the third frame with his 24th goal.

Rushing into the offensive zone on the left wing, Golden Knights forward Ivan Barbashev veered toward the slot, then left a drop pass for an on-rushing Eichel, who sizzled a wrister past Silovs’ blocker that clunked off the crossbar and entered the cage. Barbashev and defenseman Shea Theodore tallied assists.

McNabb capped the scoring by potting his third goal on an empty net at 19:01 of the final frame off an assist by Eichel.
