Korpisalo and in for the winning goal.

The Oilers had already surmounted a three-goal lead and, much as they rallied from two series deficits last season, they overcame a second disadvantage as well Sunday. With 3:02 to play in regulation, Kane gained the zone, moved the puck and got it back for the equalizer from the left faceoff circle.

Unabated by a three-goal inferno that fizzled to ash during the middle of the game, the Kings responded with a go-ahead goal with 15:32 left in the third.

Edmonton defenseman Darnell Nurse stepped up to hit winger Trevor Moore, parting the seas for a Kings rush that was started by Roy and culminated in his jumping into the play for a goal between the wickets of Campbell. Roy had superb timing in delivering his first goal of the postseason.

Edmonton came out determined to tilt the ice in the second period and the Oilers did just that, closing to within a goal with a power-play tally and then another marker at even strength.

A bit of controversy preceded the Kings’ third goal Friday, Moore’s overtime game-winner, and another came before Edmonton’s third goal Sunday. Fiala checked Draisaitl to the ice, sending the Kings on a counterattack that was blown dead because of a tripping penalty. The offense was difficult to discern, but that didn’t prevent Draisaitl from scoring his NHL-leading fifth goal of the postseason with a power-play marker from the doorstep with just 11 seconds left in the stanza for a 3-3 tie.

Draisaitl had scored from in tight 10:08 earlier. McDavid caused defenseman Drew Doughty to fall behind the net, taking a defenseman out of the play and leaving Draisaitl unmarked to receive a pass in front for a rising wrist shot.

Edmonton had gotten on the scoreboard less than five minutes into the period with another power-play goal.

Their first unit moved the puck with aplomb, setting up two one-timers for Bouchard, the second of which interrupted a nearly 60-minute shutout streak for Korpisalo.

Though their lead did not hold, the Kings tried to reward their fans in the first period for a long wait — nine years — since the team’s last playoff series victory. They piled up three goals between the 9:25 and 18:11 marks of the frame, pushing aside a pair of early near misses to open up a commanding advantage.

After two even-strength goals, the Kings’ third marker came on the power play. Fiala beat Nurse off the wall and chipped a pass into the slot to a wide-open Kopitar, who waited out Skinner and deposited the puck off his backhand.

The Kings had cushioned their edge when Arvidsson received a pass at the blue line before twirling into the zone, burning defenseman Vincent Desharnais and zooming ahead for a goal that beat Skinner to his five hole.

The Kings got their first goal from a pair of players who began the series battling injuries. Fiala, who hadn’t played since for three weeks, dragged Desharnais to the net and banked a shot off Skinner’s pad, creating a rebound goal for Vilardi.
