Phillip Danault made it 2-0 at 6:07 of the third period, getting inside position at the edge the crease and deflecting in Moore’s sharp-angled shot, which first hit off the stick of Sorokin.
Moore then scored into an empty net at 17:38 for the 3-0 final. It was his 25th goal of the season.
The Islanders were 0-for-5 on the power play, including a 5-on-3 in the first period which was cut short after forward Mathew Barzal was assessed a minor for slashing.
“If our power play would have clicked, maybe it would have made a difference,” New York coach Patrick Roy said. “We needed more traffic. When the puck is not moving as well as we wish on the power play, we need to do things a little different and get more traffic in front of the net (rather) than try to be a little fancy around and try to play around.”
NOTES: Kings defenseman Mikey Anderson had one shot and was plus-1 in 18:59 of ice time in his return after missing eight games because of an upper-body injury. … Islanders forward Matt Martin did not play because of a lower-body injury. He is day to day, Roy said. ... Defenseman Drew Doughty had the secondary assist on Danault's goal. It was his 660th point (155 goals, 505 assists) in 1,159 games, passing Butch Goring for eighth in Kings history. ... Kempe's goal was his 20th, the third straight season he's reached the mark.
