Filip Kuba scored his sixth goal of the season at 3:07 of overtime Friday as the Ottawa Senators moved into first place in the Northeast Division with a 2-1 win over the Montreal Canadiens.

After taking a pass from Daniel Alfredsson, Kuba beat Carey Price in the Montreal net with a slap shot from the top of the left faceoff circle.

Ottawa defenceman Erik Karlsson assisted on Kuba's winner, giving him four points in his last three games and 71 points in 71 games on the season.

Kuba scored on Ottawa's 33rd shot as the Senators jumped over idle Boston for first place in the Northeast, although the Bruins have two games in hand.

Colin Greening scored in regulation for the Senators, while Tomas Plekanec replied for the Canadiens.

The Senators (37-25-10), snapped a two-game slide in the process and earned a little redemption from their 3-2 shootout loss in Montreal on Wednesday. They have also collected points in five straight games. Senators goaltender Ben Bishop faced just 14 shots.

The Canadiens (28-32-12) also have points in five straight games, including three wins, as they continue their ascent out of the Eastern Conference basement.

Greening scored at 6:27 of the third period to tie the game after some good work from Zack Smith, who outskated the Montreal defence and got the puck on goal before Greening backhanded a rebound past a fallen Price.

Despite 10 combined power plays through the first two periods, there was only one goal scored, and a short-handed one at that.

Plekanec made his way into the Montreal zone with Petteri Nokelainen sat in the penalty box and fired a quick shot that seem to catch Bishop a bit off guard.

Plekanec looked as though he was going to try and split the Ottawa defence, but after taking a quick step to his left he shot and recorded his second short-handed goal of the season, and ninth for the Canadiens, at 8:18 of the first period.

Notes: Karlsson is the youngest defenceman to reach 70 points since Brian Leetch in the 1988-89 season. ... Friday's game was the second of three over a nine-day span between Ottawa and Montreal. The Canadiens were 3-2 winners in a shootout at home March 14 and the two will meet for the sixth and final time this season in Montreal March 23. ... Plekanec's goal Friday was his 139th with the Canadiens, two behind Ryan Walter for 40th all-time in Canadiens' history.
