"Keep playing the way we are; there's no reason to deviate now," said Lehner, who lowered his NHL-leading goals-against average to 2.02. "We're starting to play our game, we're playing very consistent. We're just frustrating the other teams, I think."
Chad Johnson made 25 saves for Anaheim (21-20-9), which won its previous two games after losing 12 in a row (0-8-4).
The Ducks, who went 2-2-1 on a five-game road trip, have scored two goals or fewer in 10 of their past 15 games.
"It just seemed they had more energy than we did right off the bat," Anaheim coach Randy Carlyle said. "We take a too many men on the ice penalty that opened the door for them. You know you're going to have to weather a storm in most buildings coming off a back-to-back. They're a good hockey club that's pushing for first place, and we knew that they would come with some energy."
Clutterbuck gave the Islanders a 1-0 lead with a power-play goal at 4:50 of the first period. Josh Bailey found Clutterbuck skating into the slot, where he sent a wrist shot past Johnson's blocker.
