In each of New York's wins on the trip, the opponent was limited to one goal. That included Dallas, which won 6-2 at Barclays Center on Nov. 18, and Colorado, which leads the West with 129 goals scored.
"There's some pretty dynamic talent on that team that we played tonight, and there was some in Colorado," Islanders coach Barry Trotz said. "We did a really good job against their top players. We were on top of people, and we're making plays and we're committed in the right area. Then, we can beat some pretty good teams."
Lee scored on a rebound after a shot from the high slot by Nick Leddy found its way through a crowd and went off the post and Khudobin for his 13th goal of the season.
Pitlick gave Dallas a 1-0 lead at 6:20 of the second period, ending a 16-game goal drought with his fourth of the season. He skated in from the left circle and slid the puck between Lehner's five-hole.
