The skinny: Max Pacioretty took advantage of a strong defensive effort by David Desharnais to score the winning goal in overtime to give the Canadiens a 1-0-victory over New York Islanders on Saturday night at Nassau Coliseum. Desharnais took the puck away from defenceman Thomas Hickey behind the Islanders’ net and then set up Pacioretty for his team-leading 12th goal. Said Pacioretty: “It was all Davey. I showed him my stick and I knew he was going to get me the puck.” Goalies sharp: Canadiens head coach Michel Therrien made an inspired choice when he deviated from his normal plan of having Peter Budaj start in the first half of a back-to-back series. He went with Carey Price, who made 21 saves for his second shutout this season. He has 21 for his career, tying Charlie Hodge for eighth place on the Canadiens’ all-time list. Evgeni Nabokov, who returned after missing 12 games with a groin injury, had 24 saves. Nothing special: The Canadiens had two power plays, but managed only one shot against the team with the worst penalty-killing record in the NHL. The Canadiens’ power play ranks sixth in the NHL, but is 0-for-15 over the past six games. The Montreal penalty-killing unit, which ranks fifth in the NHL, killed three Islander power plays and has allowed only one goal in the past 10 games. They have faced 26 power plays in that span.
