Mayfield and Salo each scored two goals in a game for the first time in their NHL careers.
For Mayfield's first goal, Beauvillier retrieved the puck along the boards to start a chance on the rush. He found Anders Lee, who took a shot on net. Mayfield, who'd joined the rush alongside Lee and Beauvillier, buried the rebound at the net for the first goal of the game and his first goal of the season.
Mayfield's second goal of the game came off a rush chance from Barzal, who found Mayfield on the other side of the zone. Mayfield ripped a shot from the point which sailed over Gibson's glove for the Islanders' fourth goal of the game. Mayfield, who turned 30 on Friday, started the play by disrupting a cross-ice chance on a Ducks rush.
"Our game plan starts with our forwards being able to backtrack and help us out too," Mayfield said. "They did a great job of that, that allows us to jump up. Full team effort for us to be able to jump into plays like that. It's been good so far, but we'll keep it going."
Both of Salo's shots came from the point in the third period, with his first coming just as a power play came to a close, and his second in the final minute of the game. Salo didn't have to wait as long as Mayfield for his first two-goal game, with Salo's coming in his 23rd career contest. Salo finished the game with eight shot attempts (three on net, five blocked) in 17:05.
