Doughty gave the Kings a 3-1 lead while shorthanded at 5:44 of the third period, finishing off Kopitar's pass on a 2-on-1 break despite not knowing where the puck was.

"Luckily I saw it at the last second and tried to get some wood on it," said Doughty, who had a goal and assist for the second straight game. "Great pass by [Kopitar]. You expect him to do that every game and he never disappoints."
Cizikas stuck with his wraparound shot and eventually scored with 5:37 remaining in the third period, but Kuemper made two saves in the final 35 seconds to preserve the win.
Islanders center John Tavares had a low-angle shot into an empty net with 22 seconds remaining, but the puck sailed through the crease. Tavares has two goals and one assist in six games.
"They're counting on me to produce and I haven't done that as consistently to start the season as I would like," Tavares said. "I definitely expect more of myself, especially when I get those chances."
Muzzin gave the Kings a 2-1 lead when he scored his first goal of the season at 11:32 of the second period. Halak was screened by Tanner Pearson on the play.
Kings forward Alex Iafallo kept the play alive after Halak stopped Muzzin's earlier shot when the rookie used several aggressive taps with his stick to keep Halak from covering the puck. The Kings were able to reset and eventually score their fourth goal in their past six chances with the man-advantage in sweeping their first set of back-to-back games.

"It wasn't that long ago we were talking about our power play and lack of production," Kings coach John Stevens said.
The Islanders were aggressive to start the second period and finally scored on Bailey's shot while falling to his knees at 8:56. Kuemper had a chance to clear the puck, but was indecisive on where to play it with his stick. Barzal, a first-round pick (No. 16) at the 2015 NHL Draft, had an assist for his first point.
Kopitar was credited with his fourth goal after Islanders defenseman Adam Pelech stuck out his stick trying to break up a pass for a hard-charging Dustin Brown. Instead, Pelech redirected the puck between Halak's legs to give the Kings a 1-0 lead at 12:44 of the first.
Goal of the game
Muzzin might not seem like a staple on the power play, but 14 of his 40 NHL career goals have come with the man-advantage. He has a big shot, and Pearson's pestering presence in front of net made it that much more dangerous.

Save of the game
Kuemper capped off his performance with saves against Anders Lee and Jordan Eberle in a span of 11 seconds, then benefitted from a little luck when Tavares whiffed on an open chance.
Highlight of the game
Doughty's second NHL career shorthanded goal was as much a testament to the resurgent play of Brown and Kopitar. Brown pressured Joshua Ho-Sang into a bad pass that was easily picked off by Kopitar for a 2-on-1 break the other way.

"We have to play like we did in the second period. We kind of shot ourselves in the foot a little bit by taking a couple penalties right in the midst of really tilting the ice, pouring lines on them. They were dog-tired." -- Islanders coach Doug Weight
"We go as they go, and you always want your best players being your best players. I think they have been tremendous on both sides of the puck." -- Kings coach John Stevens on forwards Anze Kopitar and Dustin Brown
