Quinton Byfield, Jordan Spence and Brandt Clarke scored for the Kings, who were the No. 2 seed from the Pacific. Kevin Fiala and Alex Laferriere each had two assists, and Darcy Kuemper made 23 saves.
“One-hundred percent it’s a missed opportunity. It’s very clear it’s a missed opportunity for us,” Kings coach Jim Hiller said. “Especially when we had great buy-in from our players. We believe we could have won the series, we believe we should have won the series.
“We didn’t, so that’s the bottom line. We had our chances to get it done, didn’t get it done.”
Byfield put the Kings ahead 1-0 at 1:19 of the first period, getting sprung on a breakaway by a centering pass from Fiala and sending a shot low stick side on Pickard.
Adam Henrique tied it 1-1 at 3:04. Brown picked up a rebound off a shot by Frederic and fired through a crowd for a deflection by Henrique over Kuemper’s right shoulder.
Clarke responded for Los Angeles just 33 seconds later to make it 2-1, taking a cross-ice pass from Phillip Danault and sending a wrist shot high in the right circle far side past Pickard.
Nugent-Hopkins tied it 2-2 on the power play at 5:55, taking a cross-ice feed from McDavid inside the left dot and scoring with a catch-and-release wrist shot past Kuemper’s blocker.
Hyman put Edmonton ahead 3-2 at 12:49, deflecting a point shot by Nurse high over Kuemper’s glove after an offensive-zone face-off.
Nurse made it 4-2 at 14:59 of the second period, sending a wrist shot from the top of the left circle past Kuemper’s blocker after Mattias Janmark allowed what looked to be a pass back from Vasily Podkolzin go between his skates to the defenseman for an open shot.
