Craig Conroy took a penalty eight seconds into the game setting up a quick start for the Oilers. Ryan Smyth
was right at the doorstep to put home a Chris Pronger rebound 34 seconds in to put the visitors ahead 1-0.
Morrison made a big stop early to keep the Oilers up by a goal. Lubomir Visnovsky blasted a one-timer in the low slot and Morrison turned it aside with a pad stop.
Morrison had a nervous moment late in the period when he fanned on an attempt to clear the puck around the boards. Derek Armstrong pounced on it but couldn't generate a quality scoring chance.
The Oilers goaltender atoned for his error several minutes later, robbing Luc Robitaille on a redirected shot by swatting it away with his blocker arm. Robitaille thought he had his 665th career goal and even raised his arms in celebration prematurely.
Shots after one period were 11 apiece for the Oilers and Kings.
Edmonton ran into some penalty trouble early in the second. Greene was penalized for a questionable delay-of-game call for clearing the puck over the glass followed by Jason Smith going off putting the Kings on a two-man advantage for 30 seconds.
Morrison was stalwart in keeping it a 1-0 game while the Kings pressed on the power play. Cammalleri was denied on a wraparound and Morrison then stuck out the pad to rob Avery on the rebound.
Just as the penalty was about to expire, Moreau had a wide open net but Nathan Dempsey slid across the crease to block the shot.
Seven minutes into the period the Kings drew even on a nice passing play between Armstrong and Robitaille. The Oilers were caught on a bad line change, sending the two Kings in on a two-on-one. Armstrong made a nice behind-the-back pass to Robitaille in the slot and he made no mistake, whistling it past Morrison glove side.
Edmonton looked to regain the lead after a high sticking penalty to Jeff Cowan was called but it was the Kings who capitalized on the Oilers power play.
After Pronger had a stick broken, Alexander Frolov sent Conroy in on a breakaway. Craig Conroy shot the puck low glove side for his 18th of the season.
Edmonton tied it up after Steve Statios corralled a nice back pass from Marty Reasoner before dishing it to Radek Dvorak who was streaking towards the net. Dvorak backhanded it just under Garon's blocker hand to make it 2-2.
As the second period was near its conclusion, Edmonton had a great chance to take the lead and gain some momentum heading into the third with a 1:18 two-man advantage. Instead, it was the Kings who picked up momentum as the killed off both penalties with ease.
Shots in the second were 10-6 for Los Angeles.
Edmonton took the lead at 3-2 in the third thanks to a goal by Raffi Torres. Torres, Stoll and Laraque did a good job cycling the puck along the right side boards. Torres skated to the front of the net and Laraque found him with a neat backhand pass.
Less than two minutes later while on the penalty kill, Moreau and Peca broke in on a two-on-one. Peca threaded a pass to Moreau past Lubomir Visnovsky. Moreau made no mistake in flicking a shot behind Garon to double the Edmonton lead.
Not to be outdone, Morrison made a pair of brilliant saves at the other end of the ice just as the penalty expired. He robbed Cowan and then slid across to deny George Parros on the rebound.
The Kings went back on the power play on Greene's second delay-of-game penalty of the night and this time they capitalized. Michael Cammalleri picked up the puck in the corner off Pronger before skating in front where he snapped one high over the shoulder of Morrison.
With Edmonton on a late third-period power play, Garon made a huge stop stretching his pad out to deny Moreau on a backhand one-time attempt.
The Oilers kept on the attack as the third period progressed and it paid off in the team's fifth goal of the night. Fernando Pisani made a nice no-look pass to Todd Harvey in front who fired a bullet past Garon to put Edmonton up 5-3.
