The Islanders’ dogged work for the opening 10 minutes of the second period helped make good on Roy’s promise on Saturday night. They scored three goals during that stretch — those goals the result of won battles, races, and every inch of contested ice — to fuel a 6-3 win over the Penguins at USB Arena in Elmont, N.Y.

Duclair gave the Islanders a 2-1 lead at 5:39 of the middle frame off the rush. Kyle Palmieri collected a puck just inside the Penguins’ zone before he found Duclair cutting toward the low slot on an odd-man rush for a finish past Jarry’s blocker.

Casey Cizikas and Anders Lee each scored twice and the New York Islanders beat the Pittsburgh Penguins 6-3 on Saturday night. Jean-Gabriel Pageau and Anthony Duclair also scored, and Mathew Barzal and Alexander Romanov each had two assists for New York, which had lost three of four. Ilya Sorokin finished with 22 saves.
