Roloson made 15 of his 39 saves in the second period, four more in overtime, then stopped both shots he faced in the shootout to lead the Edmonton Oilers to a 3-2 victory Saturday.
Dustin Penner had a goal and an assist, Shawn Horcoff scored a power-play goal and Ales Hemsky had two assists for the Oilers, who began this four-game trip with their fourth shootout victory of the season despite getting outshot 24-8 through the first two periods and 41-21 for the game.
"Dwayne was outstanding," coach Craig MacTavish said. "He played exceptionally well. It was a great performance."
The Oilers averaged 36.2 shots on goal in their previous five games, compared to 25.4 by their opponents. The Kings came in allowing an NHL-low 27.2 shots per game, tied with San Jose.
The Kings have lost two straight following a 7-1 stretch. Rookie defenseman Drew Doughty scored a power-play goal for Los Angeles in the second period, and Dustin Brown tied it during another power play with 26 seconds left in the third period.
The Kings had a great chance to tie it with about 12 minutes left in regulation. Edmonton defenseman Tom Gilbert tried to flip the puck out of his zone and it struck Kings center Patrick O'Sullivan, who went in on a breakaway and hit the left post after beating Roloson to the stick side.
Los Angeles got another opportunity late in the third after a penalty on Andrew Cogliano for tripping Brown put them on the power play. Michael Handzus won a faceoff from Kyle Brodziak with goalie Jonathan Quick pulled in favor of a sixth attacker, and the Los Angeles captain redirected Alexander Frolov's one-timer from the left point with the blade of his stick for the equalizer.
"We got into some penalty trouble and it kind of took the wind out of our sails a little bit," Gagne said. "They're a good team, they've been playing pretty well and they were coming hard there at the end. It was a tough win, and it was a good thing we were able to get it in the shootout."
Edmonton gave the Kings an early wakeup call in this matinee affair when Sheldon Souray carried the puck through the neutral zone and rang one off the left post about 1½ minutes after the opening faceoff. The Oilers then opened the scoring with their first official shot on net.
Penner got a pass in the low slot from Hemsky and beat Quick to the glove side with a one-timer at 4:58 of the first period. Horcoff scored at 13:11 on another one-timer from shot range, beating Quick high to the glove side about a minute after drawing a hooking penalty from Anze Kopitar.
The Kings didn't take the two-goal deficit lying down in front of their 10th sellout crowd. Immediately after Horcoff scored, Doughty went after Horcoff and both were sent off for roughing. Less than two minutes later, Gagner and Kings defenseman Jack Johnson got into a fight and were joined in the penalty box by Ladislav Smid and Kyle Quincey with coincidental roughing minors.
"They were going after some of our players and we went after some their players. That's just the nature of the way the playoff chase is going to be," Brown said. "These are games that are going to be emotional games, especially when they're a couple of points ahead of us. If we came out better in the first period, we might win that game in regulation."
Another 72 seconds ticked off the clock before Raitis Ivanans mixed it up with Oilers enforcer Zack Stortini right after a faceoff. For good measure, Brown got into a scuffle with Souray just five seconds before the first intermission and both received roughing penalties.
"I think guys on both teams woke up on the wrong side of the bed," MacTavish said. "It was a very competitive game, and indicative of where everybody is in the standings and how important these games are. It was two teams that desperately wanted to win, and it was a heck of a hockey game."
After going 0-for-6 on the power play in Thursday's 2-0 loss to Calgary, the Kings got on the board at 6:29 of the second period during a 5-on-3 advantage, after staggered penalties against rookie Theo Peckham for interference and Steve Staios for holding. Johnson beat Roloson to the glove side with a screened 50-foot slap shot as Handzus was parked at the edge of the crease -- as he was on the tying goal.
Doughty's fourth goal came with 16 seconds left on Peckham's infraction. Peckham was playing in his fourth NHL game after being recalled to replace former Kings defenseman Lubomir Visnovsky, who had season-ending shoulder surgery on Thursday.

- Penner, who signed with Edmonton as a restricted free agent in August 2007 after winning a Stanley Cup with Anaheim, had seven goals in 17 career games against the Kings.
- The visiting team has won all three games in this season series, which concludes April 7 in Edmonton.
