John Carlson had a goal and an assist for the Capitals (3-3-0), who scored four goals in the third after entering the period trailing 2-0. Nic Dowd and Lars Eller scored, Orlov had three assists, and Darcy Kuemper made 22 saves.
"Usually they or I, or we both together have a good idea when we don't play well," Washington coach Peter Laviolette said. "It didn't feel like it was 2-0 and so we just stayed with it. The big thing was putting more pucks to the net, trying to generate more chances, whether it be the first chance or the second chance, third chance."
Washington outshot Los Angeles 17-13 in the third period.
Viktor Arvidsson had a goal and two assists, and Trevor Moore had two assists for the Kings (3-4-0) who finished 3-2-0 on their five-game road trip. Sean Durzi and Phillip Danault scored, and Jonathan Quick made 28 saves.
"You look at it at 3-2, but then obviously the last two, the [6-1 loss at] Pittsburgh (on Thursday), we weren't real pleased with. This game wasn't a disaster, although we gave up four in the third to lose it," Los Angeles coach Todd McLellan said. "So, we're still not where we need to be, quite frankly, and I think that's evident in the amount of goals we've given up."
