MONTREAL -- Tyler Seguin scored 14 seconds into the third period and set up David Krejci's eventual game-winning goal 1:51 later as visiting Boston posted a fifth straight victory over its Original Six rival, 2-1, on Wednesday.

Krejci also recorded an assist and Tuukka Rask stopped 20 shots to snap a personal five-game losing streak against the Canadiens. The Bruins' third-period flurry led them to their fifth win in six contests (5-1-0) and a spot atop the Eastern Conference.

Defenseman P.K. Subban netted a power-play goal and Carey Price survived a pregame scare to finish with 21 saves for Montreal, which saw its five-game home winning streak come to an end.

With the game tied at 1-1, Seguin skated into the offensive zone before feeding Milan Lucic. The bruising left wing wired a centering pass from the left faceoff circle which caromed off Krejci's stick and into the net. The tally was Krejci's third of the season and second in three games.

Subban opened the scoring midway through the second period as his blast from the right point deflected off Rich Peverley's stick and over the glove of Rask. Seguin answered early in the third, accepting Krejci's centering pass on the doorstep and backhanding it past Price.
