Keller gave Arizona a 1-0 lead at 4:58 of the first period, skating into the high slot for a shot that deflected off Islanders defenseman Nick Leddy. It was his first goal since scoring twice against the Philadelphia Flyers on Jan. 4.
"I felt the last few games that this is the best they played as a line," Coyotes coach Rick Tocchet said of the Keller-Nick Schmaltz-Phil Kessel line. "If they can just commit to playing in the right way in their own end, they're going to get chances the other way."
Conor Garland made it 2-0 at 3:53 of the third period, tapping in a backhand cross-crease pass from Christian Dvorak into the open net. Garland is the first Coyotes player to score 20 goals since Keller had 23 in 2017-18.
Anthony Beauvillier cut it to 2-1 at 6:42 of the third when he redirected Greene's pass in the left circle off the right post and in. The goal ended the Islanders' scoreless streak at 166:46.
"It's been tough for us lately to find goals and we got one there from Beau to give us life, we just weren't able to get the second one," Lee said. "Chances over and over. You just got to find a way to put it in."
Before that, Raanta stopped Brock Nelson on a breakaway at 6:53, and he preserved the 1-0 lead in the second period when he kept Devon Toews' shot from completely crossing the goal line on a redirection with his right pad.
"We hit four posts, had a breakaway, put one off the knob of [Raanta's] stick, and had a puck in the crease. We talk about a game of inches, but it's really a game of centimeters right now," Islanders coach Barry Trotz said. "I thought as much as [Arizona] deserved to win that game, so did we."
