The Habs got on the board early in the second with a power play goal. It followed a shorthanded opportunity by the Rangers, however, but after Jacob Trouba's wrister was stopped by Montembeault, Cole Caufield, Christian Dvorak, and Kirby Dach passed the puck around as they entered the zone before Dach fired a wrister that beat Shesterkin for his eighth of the season.
Dvorak and Caufield picked up the helpers.
The goal, scored at 4:54 of the second, also helped Dach set a new career high in points with 27, and put him in sole possession of the team lead in power play points this season with 12.
