WINNIPEG, Manitoba — The Winnipeg Jets were in rhythm and the Vegas Golden Knights looked rusty.

Or, maybe the Jets are just that good.

Dustin Byfuglien scored about a minute after the puck dropped and Winnipeg built a three-goal lead early in the first period and went on to beat Vegas 4-2 on Saturday night in Game 1 of the Western Conference finals.

While the Jets played at home less than 48 hours after advancing past top-seeded Nashville on the road, the Golden Knights were off for nearly a week after eliminating San Jose in the second round.

“We didn’t have much of a rest,” Byfuglien said. “We’re still in game mode.”

Patrik Laine and Joel Armia had goals 46 seconds apart to put the Jets up 3-0. Mark Scheifele gave Winnipeg a 4-1 lead midway on a power play through the second period with his 12th goal this postseason.

Brayden McNabb scored midway through the first and William Karlsson had a power-play goal late in the second period to pull Vegas within two, but the expansion team couldn’t get closer.
