Vegas leads best-of-7 series 3-0
LOS ANGELES -- The Vegas Golden Knights can become the first NHL team to sweep their first Stanley Cup Playoff series in their inaugural season in Game 4 of the Western Conference First Round against the Los Angeles Kings at Staples Center on Tuesday.

Vegas scored three goals in the third period to defeat Los Angeles 3-2 in Game 3 on Sunday and would join the Pittsburgh Penguins (1970) as the second team in NHL history to win their first four playoff games.
The Kings are one of four NHL teams to win a series after trailing 3-0, defeating the San Jose Sharks in the first round in 2014.
Here are 5 keys for Game 4:

1. Don't look past Game 4

With 11 players on their roster who played against the Sharks in 2014, the Kings understand they can't win the series in seven games without a victory in Game 4. The Golden Knights have enough playoff-tested veterans, including forwards James Neal and David Perron to realize they can't look ahead to a possible second round showdown against the Sharks or Anaheim Ducks until they get another win to close out this series.
"Down three, up three, you are focusing on winning one game, and that's going to be our focus," Kings defenseman Jake Muzzin said.
Vegas has won each game in the series by one goal.
"Playoffs are all about momentum, so let's keep the momentum," Vegas coach Gerard Gallant said. "We're playing well, we're winning hockey games, so don't look and it and say, 'We got four chances to win one game.' We better come out and play our best game."

2. Controlling emotions

Game 3 went a long way in establishing the Kings and Golden Knights as rivals with each side trading big hits and plenty of retaliation. Kings defenseman Drew Doughty said Monday, "I don't like a lot of those guys on that team and I'm pretty sure almost every guy on that team doesn't like me, so it's just part of playoffs."
It nearly cost Vegas when Jonathan Marchessault hit Doughty on a high-sticking penalty at the end of the second period. Dustin Brown nearly gave Los Angeles a 2-0 lead on the ensuing power play but the puck skipped over his stick early in the third. The Golden Knights got lucky, but there are no guarantees it will happen again if they cannot maintain their composure.

3. Put pucks on net

Anze Kopitar's late goal to put the Kings within 3-2 in Game 3 ultimately wasn't enough, but it might have established the blueprint to get their offense on track. Oscar Fantenberg threw a puck toward the net and Kopitar tipped it in for his first goal of the series.
The Kings admit they haven't created enough chances to make those kind of plays, notably from the blue line. Los Angeles defensemen had the fifth most points in the regular season, but have three points (one goal, two assists) in the series.
"You can give [Vegas] some credit," Kings coach John Stevens said. "They are probably more aggressive on the top than any team we've played this year, and I just think we have to do things a little bit quicker. When you only score three goals in the series to this point, there's not a lot of production going on."

4. Goaltending duel

Marc-Andre Fleury of the Golden Knights and Jonathan Quick of the Kings seem to elevate their game in the playoffs, and this series has been no exception.
"All great goalies have it, and even Quick has played well in this series," Golden Knights forward Ryan Carpenter said. "It seems like [Fleury is] so darn competitive. Watching him just even in practice, he hates getting scored on, and so I think that competitiveness and that desire to be great carries itself over into big games like this."
Fleury ranks first in the playoffs with a 0.84 goals-against average and is tied for first with a .970 save percentage; Quick is fourth with a 1.69 GAA. Fleury needs one win to pass Dominik Hasek (65 wins) for sole possession of 11th place in career playoff wins. Quick needs one win to tie Rox Hextall (47 wins) for 21st place.

5. Play a complete game

The stop-and-start nature of the series was evident in Game 3. The Kings dominated in the first period, but their inability to build on a 1-0 lead came back to bite them. The Golden Knights were erratic, needing pressure in the second before winning it with a late push in the third. Whichever team finds the consistency that has been lacking will have a significant edge.
"It's do-or-die now, so we got to make sure we're ready for the full 60 [minutes]," Kings forward Trevor Lewis said.
