Jack Hughes scored for the Devils (32-22-6), who have alternated wins and losses in their past 10 games (5-5-0). Jake Allen allowed five goals on 36 shots before leaving the game with 1:42 remaining due to cramping. Nico Daws replaced him and did not face a shot.
“I thought we had our share of chances, especially in that second period. But even in the first period we had a couple and the game's right there,” New Jersey coach Sheldon Keefe said. “The game just kind of gets away at the end there, but we're right there all the way throughout despite being outplayed a little bit.”
Lehkonen gave Colorado a 1-0 lead at 8:54 of the first period. Necas forced a turnover by Brett Pesce behind the net and passed out front to Lehkonen, who beat Allen five-hole with a backhand from the top of the crease.
“That was a huge game for our team because morale was kind of low coming out of the two road games,” Avalanche coach Jared Bednar said. “We want to embrace this stretch run, right? That's what we want to do. We want to enjoy it, we want to embrace it, we want to use the pressure to push our game to another level consistently.”
