Joel Armia and Jordan Harris each had a goal and an assist for Montreal (23-28-8), which ended a five-game losing streak (0-5-0).
“We got outshot pretty good tonight, so it was a fantastic game by [Montembeault], and I can’t speak enough of how he’s been all year,” Harris said.
Alex Kerfoot scored in his 500th NHL game, and Connor Ingram made 17 saves for Arizona (23-30-5), which is 0-11-2 during the losing streak.
“We’re in that kind of stretch,” Coyotes coach Andre Tourigny said. “You watched the game. We had 77 percent of the scoring chances tonight. We had a lot of possession in their zone, quality shots. Their goalie stood tall. There’s always nitpicking, we always can find a few things. We could have a little bit more traffic in front of him. We did not reload properly on two of their goals.
“There’s never a perfect game, but if you look all in all, I don’t want to find excuses or I don’t want to blame the players for an effort like tonight, that’s for sure.”
Armia put Montreal ahead 1-0 at 7:52 of the first period with a low wrist shot past Ingram’s glove off a pass from Alex Newhook on a 2-on-1.
