The Kings converted on four of their first six power-play chances and improved to 2-0-0 against the Oilers this season. It was the first time Los Angeles scored four power-play goals in a game since April 5, 2012.
Fiala had his sixth game with at least three points this season and second consecutive. It was the first time in Kings history two players scored multiple power-play goals in a game.
Kailer Yamamoto, Ryan McLeod and Connor McDavid scored for the Oilers in the opener of a four-game road trip after Edmonton dropped three of four at home. The Oilers were 0-for-6 on their power-play chances.
Stuart Skinner was bombarded for three goals on 24 shots before he was replaced early in the second period. Former Kings goalie Jack Campbell came on after Kempe gave Los Angeles a 3-1 lead at 3:51 of the second period.
The matchup was the first between the teams at Los Angeles since Game 6 of a first-round playoff series last season. Edmonton advanced in seven games.
One game after recording a hat trick Saturday at Vegas, Fiala made it five goals in four periods when he scored twice in a span of 1:51 on separate first-period power plays. The goals gave him 15 on the season.
Yamamoto got one for Edmonton when he scored with 2:58 remaining in the first period when he deflected a shot by Darnell Nurse off the shaft of his stick for his fourth.
Kempe scored his second goal of the second period for a 4-1 lead at 11:38 on a blistering shot from the right circle that Campbell actually snagged with his glove. On replay review, the puck was ruled to have crossed the goal line while in the webbing of the glove.
The man-advantage success gave the Kings 24 power-play goals at home this season. The teams combined for 13 penalties.
McLeod scored for Edmonton at 16:36 of the second period, his fourth.
Iafallo scored his seventh of the season for the Kings at 7:44 of the third, while McDavid scored less than two minutes later for his NHL-leading 34th. Arvidsson scored into an empty net with 1:42 left.
Anze Kopitar’s first-period assist for the Kings on Fiala’s first goal of the night helped him to reach a pair of milestones. Not only did Kopitar record his 1,100th career point (376 goals, 724 assists), he also reached 600 career points at home (199 goals, 401 assists).
Kopitar has played 1,254 games over 17 seasons, all with the Kings and is third in Los Angeles history in home points behind Luc Robitaille (669) and Marcel Dionne (700).
