Anze Kopitar scored twice and the Kings beat the Senators 5-2 on Saturday afternoon for their sixth straight win.
The Kings took control of the game, scoring twice in the first 4:18.
''We kind of slacked a little after we were up 3-0,'' Kings defenseman Drew Doughty said. ''We let them back in the game and they started outshooting us and taking the play to us and after they got those two we had to get back in the game.''
Los Angeles moved to 22-7-4.
Ottawa continues to struggle with afternoon games. The Senators are 1-6-1 when the puck drops before 7 p.m.
''They got off to a better start than us so they carry momentum early,'' Ottawa's Jason Spezza said.
Joe Corvo and Erik Karlsson scored for the Senators, who saw their home record drop to 6-9-3.
L.A. took control early on as King opened the scoring just 21 seconds into the game beating Anderson blocker side.
Carter's goal at 4:18 put an end to Anderson's afternoon.
''I had a bad day,'' Anderson said. ''Everyone has a bad day once in a while. It just so happens the red light goes on when I make a mistake. It's all magnified that way. It stinks, but I can't focus too much on it, I've got to move forward and put it behind you.
''It's a little blip on the radar and one of those things where the sooner you forget about it the better off you'll be.''
Senators coach Paul MacLean admitted that Anderson's rough start made it that much more difficult for his team.
''We didn't get saves early,'' MacLean said. ''That team that we played is a very good team. They play a certain way and they play that way the whole game and they make it difficult for you and they certainly did that (Saturday).''
While Anderson had his share of struggles his teammates say they didn't offer much help.
''It's a (bad) goal, but at the same time we can't just put it on (Anderson) in that situation,'' defenseman Erik Karlsson said. ''The things he's done for us in the past is probably way more than just one unlucky bounce there so we should be able to clean it up there for him. Obviously today we didn't have his back like he usually has ours.''
Kopitar made it 3-0 after beating Lehner from in close at 12:56.
That marked the 18th straight game in which the Kings did not allow a goal in the first period.
''We just keep winning,'' Stoll said. ''There's just a bunch of things going right right now. We just have to make sure we keep on top of it.''
The Senators scored at 13:51 of the second as Corvo was able to jump on Spezza's rebound and beat the 23-year-old Jones on the left side.
Ottawa made things close as Karlsson made it 3-2 at the four-minute mark of the third, but were never able to score the equalizer as Jones was solid.
''We stuck to it as good as we could,'' Karlsson said. ''We won the second period and got an early goal in the third, but unfortunately wasn't able to hold on for the tie.''
Stoll made it 4-2 at 13:18 of the third as he picked up a Doughty rebound and Kopitar scored his second of the game on the power play with just over three minutes remaining putting an end to any hopes of a Senators comeback.
