John Carlson scored with 53 seconds remaining in the third period for the Washington Capitals in a 4-3 win against the Los Angeles Kings at Capital One Arena in Washington on Sunday.

Carlson, who also had an assist, scored on a long shot through traffic from along the right boards to give the Capitals (19-13-6) their first win in three games.

“This was an important game for our group, and you could feel that at ice level,” coach Spencer Carbery said.

Nicolas Aube-Kubel had a goal and two assists for his first three-point NHL game, Nic Dowd had a goal and an assist, and Alex Ovechkin had an assist to extend his point streak to five games. Darcy Kuemper made 38 saves.

“Obviously, we haven’t had the easiest time scoring this year, and kind of when we were winning games early on in the season, we were getting contributions from everyone,” said forward Dylan Strome, who scored a goal. “Every line was scoring on any given night, and we kind of lost that for a little bit where no one was really scoring for the last five, six games.”

Kevin Fiala scored twice, and Adrian Kempe had a power-play goal for the Kings (20-10-6), who lost a season-high fifth straight game (0-3-2). Cam Talbot made 30 saves.

“We just have to make sure next game we’re ready to play 60 minutes,” Fiala said. “I feel like we started well, and they score at the bad moments. At the end as well, one minute to go or whatever, those moments we have to tighten up.”

Fiala put Los Angeles back ahead 3-2 at 1:01 of the third period, scoring on the power play from close range after Quinton Byfield forced a turnover behind Washington's net.

Aube-Kubel tied it 3-3 at 8:36 on a long wrist shot.

“Fourth line was unbelievable all game, so credit to them,” Strome said. “They got the ice time tonight, and they deserved it. Not only just did they get the goals, but they got the chances, too. They were great defensively and not enough good things to say about them. They’re really good line and hard to play against.”

Dowd put the Capitals up 1-0 at 4:22 of the second period with a backhand from the slot on a 2-on-1 that was set up by Carlson.

“I love what Nic Dowd’s line does there driving the puck down into the offensive zone and then doesn’t settle to just hold it,” Carbery said. “There’s a couple plays to be made there, and they made them, and ‘Dowder’ does a great job on the flash screen and Johnny Carlson delivering the puck.”

Kempe tied it 1-1 on the power play at 7:12, scoring with a one-timer from the top of the right circle off a pass from Drew Doughty. Anze Kopitar had the secondary assist.

Fiala put the Kings ahead 2-1 at 13:02 when he put in Phillip Danault’s rebound from the low slot after waiting out Kuemper. 

“We just tried to play a simple north-south game, you know, and just attack the net front,” Fiala said of his line with Danault and Arthur Kaliyev. “Overall, it was a better night for us.”

Strome tied it 2-2 at 15:35. Max Pacioretty stole Pierre-Luc Dubois’ backhand pass in the offensive zone, which created a 2-on-0 for Ovechkin and Strome, who finished it off from the top of the crease.

It was Pacioretty’s first point in three games for Washington.

NOTES: Ovechkin has four assists in his past three games and six points (two goals, four assists) during his five-game point streak. ... Kempe’s goal was the 295th time Kopitar and Doughty factored into the same goal, breaking a tie with Sidney Crosby and Kris Letang of the Pittsburgh Penguins for third by a forward and defenseman in NHL history. Wayne Gretzky and Paul Coffey were involved in 350 goals for the Edmonton Oilers and Kings, and Phil Esposito and Bobby Orr were involved in 306 goals for the Boston Bruins. … Kempe has three goals in his past two games and nine points (six goals, three assists) in his past seven games. … Capitals forward Tom Wilson briefly left the game in the third period because of a bloody nose. Carbery did not know if Wilson broke his nose. … Kings defenseman Brandt Clarke had one shot and a minus-1 rating in 15:43 of ice time in his season debut.
