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.
Right now I'm just happy to be back and get through this season and make sure I do my job. I've never had an issue with having to prove myself again and I'll try to do it again. We'll see where it takes me.
