Robin Lehner made 25 saves for the Golden Knights (41-31-5), who have lost back-to-back games and failed to gain ground in the playoff race. They trail the Los Angeles Kings by three points for third place in the Pacific and are four points behind the Dallas Stars for the second wild card into the Stanley Cup Playoffs from the Western Conference.
"We have to find a way to win hockey games," Vegas forward Jonathan Marchessault said. "For the first time, we're going to need help from other teams. They're going to need to lose. That's just the way it is."
The Golden Knights have five games remaining.
"We got to win them all. It's pretty simple, we got to win them all," Vegas coach Peter DeBoer said. "Circumstances have put us in a situation here where we have no margin of error. That's a tough way to play. … The work in what has happened all year and what has happened the whole year has put us in a spot where we don't have the luxury to relax and play loose this time of the year. We don't have that. We've got to make sure we handle that and find a way to stick some pucks in the net."
