BOSTON — Carey Price made 34 saves to lift the Montreal Canadiens to a 3-1 victory and a season sweep over the Boston Bruins on Sunday night.

Dale Weise and Max Pacioretty each had a goal and an assist for the Canadiens, who completed their first regular-season sweep of Boston since taking all eight meetings in 2007-08.

Price has won seven of eight and allowed 11 goals in that span. He extended his shutout streak against Boston to 159:25 until David Pastrnak scored with 4:31 remaining.

Pastrnak cut Montreal’s lead to 2-1 when he batted the puck toward the net and Price appeared to have made the stop, but his glove was behind the goal line and after replay, the goal was allowed.

Weise gave Montreal a 1-0 lead 38 seconds into the second period when he converted a cross-ice pass from Pacioretty and beat Tuukka Rask.

Rask made 31 saves, but dropped to 3-13-3 against Montreal for his career.

Pacioretty scored on a breakaway 56 seconds into the third period when Weise fed him the puck after Zdeno Chara collided with Dougie Hamilton for a 2-0 lead.

Boston has one win in its last 11 games against the Canadiens, including six straight home losses.

Andrei Markov added an empty-net goal with 31 seconds remaining to cap the scoring for Montreal.

The Bruins had no power plays for the third time this season and are six points ahead of Florida for the final playoff spot in the Eastern Conference.

Boston suffered its second regulation loss at home in its last 13 games. . David Krejci has one goal in his last 15 games, while Chara has one goal since Oct. 21. for the Bruins.
