Desharnais, whose scoring drought even attracted the attention of Montreal's new mayor, perched in front of the net to redirect Josh Gorges' drive in the first period. The goal stood after a video review to determine whether Desharnais had scored with a high stick.
Travis Moen also scored his first of the season, and Daniel Briere added a goal for the Canadiens, who have won two straight.
Ovechkin scored on a last first-period power play and again in the third period to give him an NHL-leading 19 goals.
I think everybody wanted the puck tonight. Everybody wanted to be part of the solution and it reflected on the way we played. It's tiring when you have to chase the puck but tonight was one of those nights where everyone really wanted to make a play and wanted to have an impact on the game.
