Tomas Tatar scored the tiebreaking goal on a deflection with 1:17 left in the third period and the Montreal Canadiens beat the Chicago Blackhawks 3-2 Sunday for their third straight win.
Max Domi and Shea Weber scored scored in the first period to give Montreal an early lead. Carey Price, starting for the seventh straight game and 11th in the last 12, stopped 37 shots.
Patrick Kane scored twice to tie the score for Chicago, which has lost seven straight and nine of its last 10. Corey Crawford finished with 25 saves.
The reeling Blackhawks fell to 3-11-2 under coach Jeremy Colliton, who replaced Joel Quenneville on Nov. 6.
On the go-ahead goal, after a failed clearing attempt by the Blackhawks, Jeff Petry shot from the left point into traffic in front of the net. The puck went off the tip of Tatar's stick and past a screened Crawford.
Chicago went 1 for 8 on the power play, failing to muster much pressure during a six-minute advantage early in the third.
Domi and Weber scored 1:31 apart early in the first period to give the Canadiens a 2-0 lead about 7 1/2 minutes in. It marked the 10th straight game an opponent scored first against the Blackhawks.
Domi converted a rebound of Mike Reilly's shot from the point 6:05 in after Reilly's drive struck Andrew Shaw in front of the net and dropped to the ice. It was Domi's team-leading 14th.
Weber, playing his sixth game after knee surgery, ripped in a rising screened shot from the top of the right circle for his third after taking a feed from Kenny Agostino.
Kane connected on the Blackhawks' third power play of the first and cut it to 2-1 as he beat Price from the right circle with a screened shot on the short side with 59 seconds left in the period.
Chicago has been outscored 22-5 in the first period in the last 10 games and has had a lead only in two contests - one time was when the Blackhawks came from behind for a 5-4 overtime win at Florida on Nov. 24.
Kane's second of the game and team-leading 15th tied it 2-all with 7:05 left in the second. Following a faceoff in the Montreal zone, Kane drifted into the right circle, took a pinpoint cross-ice pass from Dominik Kahun and one-timed a rising shot over Price's shoulder.
Chicago wasted three power plays covering six consecutive minutes early in the third when Tomas Tatar was sent off for cross-checking at 1:58, then Jordie Benn got a double-minor for high-sticking Dylan Strome in the face at 3:58. The Blackhawks managed just six shots - and no rebounds - during long man advantage and Price turned them all away.
Montreal then failed to connect on two power plays, including a 55-second 5-on-3 advantage, midway through the third. Crawford was sharp during the span, thwarting several close-in attempts.
