Lindgren helped Washington hang on in the third period, when it was outshot 15-3. He has won five of his past six starts.
“I thought the guys did a good job in front of me tonight,” Lindgren said. “Felt like I saw a lot of pucks, which is what I need to do. The Kings could be the best team we've seen all year. For us to come in here in a tough building and get the two points was a big one.”
Connor McMichael and Anthony Mantha each had a goal and an assist, and Aliaksei Protas had two assists for the Capitals (11-6-2), who lost their previous two games. They visit the Anaheim Ducks on Thursday.
“This is a big deal,” Mantha said. “The Kings are really good. They're well-balanced, and we found a way.”
Arthur Kaliyev scored for the Kings (13-4-3), who had won five in a row and had the last 11 shots on goal in the game. Cam Talbot made 13 saves.
It was their second regulation loss in the past 15 games (11-2-2).
“I didn’t think we were a disaster,” Los Angeles coach Todd McLellan said. “I don’t think we played poorly. But early in the game, we gave up two goals based on details. And when you don’t score four or five in a night and you’re going to have those nights, those details become important.”
Anze Kopitar thought he had tied it 2-2 for the Kings at 11:10 of the third, but Capitals coach Spencer Carbery successfully challenged that Kopitar had entered the zone offside.
“Some games you’ll play not as good and score five, so it happens,” Los Angeles center Phillip Danault said. “It’s not that we didn’t try; we definitely tried hard and we didn’t play bad. Yeah, [it] happens sometimes.”
