Sorokin had a stellar save early in the third, doing the splits on an attempt by Tatar, to keep the Islanders within two.

However, Mercer pushed New Jersey's lead to 3-0 on a 2-on-1 rush as he got a pass from Andreas Johnsson between the circles, went forehand-backhand and lifted the puck over Sorokin for his fourth of the season at 5:46.

Hamilton, back after missing three games with a lower-body injury, fired a slap shot from the top of the right circle to make it 4-0 with 3:27 left. It was his third.

With the Devils leading 1-0 after 20 minutes, Casey Cizikas fired a one-timer from the right side that Blackwood caught in his chest with 7:18 remaining in the second to keep the Islanders off the scoreboard.

Tatar made it 2-0 on the power play as he deflected Hamilton's shot from the point past Sorokin for his first with 50 seconds to go.

Blackwood made a nice stick save on Mathew Barzal just 1 1/2 minutes into the game. Sorokin slid to his left to deny Alexander Holtz nearly three minutes later, and had a right pad save on Mercer with 8 1/2 minutes left in the period.

New Jersey got on the scoreboard first. With New York on a power play, the puck came out of the corner and squirted out in front. P.K. Subban fired a shot that was stopped by Sorokin, who also denied Nico Hischier's follow from the left side. However, the rebound went to the goalie's left and Kuokkanen quickly put it into an open net for his third with 7:48 left.

New York had a chance to tie it, but Blackwood gloved Oliver Wahlstrom's shot from the right faceoff dot with just under six minutes left in the first.
