The Capitals, Islanders and Penguins each have six games remaining. The Islanders play the Capitals in Washington on April 6, the final day of the regular season.
"It just feels right the way we play," Islanders coach Barry Trotz said. "When you play right, it feels right, and you don't really worry about the score as much. … Just play and then we can frustrate teams, we can get on you and the results sort of come."
The Coyotes (36-33-7) finished 0-3-1 with four goals on their four-game road trip and are two points behind the Colorado Avalanche in the race for the second wild card into the Stanley Cup Playoffs from the Western Conference.
