Tony DeAngelo scored for the Islanders (29-27-7), who had won four of five, including 4-2 at the San Jose Sharks on Saturday. Marcus Hogberg made 24 saves in his first game since sustaining an upper-body injury in a 3-2 overtime win against the Carolina Hurricanes on Jan. 25.
"That's tough to do, playing your first game in quite some time," New York forward Kyle Palmieri said of Hogberg. "We didn't play well enough in front of him, and he kept us in it and gave us a chance to try and find our legs and find our way back into the game."
The Ducks took a 1-0 lead at 17:52 of the first period. McTavish sent a spinning backhand pass to Cutter Gauthier, who quickly touched it to Colangelo cutting through the slot. Colangelo then waited out Hogberg before lifting the puck into the net.
"Playing with two top five picks, there's a reason they were drafted so high, and they're unbelievable players playing in the League at a very young age," Colangelo said of McTavish and Gauthier. "I think we read off each other very well and we get along great, so it's been a lot of fun."
Helleson extended the lead to 2-0 at 14:56 of the second period. He scored with a wrist shot from the right point that made its way through traffic before hitting the right post, banking off Hogberg's left skate and deflecting in near the opposite post.
McTavish scored a power-play goal on a 2-on-1 rush 43 seconds into the third period to make it 3-0.
"If I just save the puck there in the third period, we have the best chance to get back into it," Hogberg said.
