"It wasn't a terrible game, by any means," New York forward Josh Bailey said. "I thought we did some good things. I thought we came out on the wrong end of the first period, or maybe it could've gone the other way. They have a good team over there and they play well too."
Cogliano scored his first goal of the season at 11:59 of the first period to give the Stars a 1-0 lead. Jamie Oleksiak's centering pass went in off Cogliano's right skate in the crease.
"It feels good," Cogliano said. "It's been a tough stretch for me, personally, offensively. I think I just try to approach every game just doing what I do. I have other jobs to focus on with my line and helping the team win. It's always nice to contribute."
Radulov, who was a healthy scratch for a 3-2 overtime win against the Winnipeg Jets on Thursday, scored with a wrist shot from above the circles through traffic on the power play at 16:02 to make it 2-0.
"I thought we came out and had a really good start in the first seven or eight minutes," Islanders coach Barry Trotz said. "They got some chances towards the end of the period, took it over, and got a goal. I thought we were really good in the second for a good stretch, and we were good in the third.
"At the end of the day, it was the two power-play goals. They have a good hockey team, and I thought it was a well-played game."
