Max Pacioretty had two goals, Dale Weiss scored on a penalty shot, and the Montreal Canadiens downed the rival Boston Bruins 5-1 on Thursday night for their fourth straight win.

Lars Eller and Jiri Sekac also scored for Montreal (12-4-1), which saw Sergei Gonchar's debut after he was acquired Tuesday in a trade with Dallas.

Dougie Hamilton scored a power-play goal for Boston (10-8-0), which lost badly for a second game in a row after a 6-1 setback in Toronto on Wednesday night. The Bruins were playing a third game in four nights.

With Tuukka Rask pulled after allowing four goals on 16 shots in Toronto, Niklas Svedberg got the start for Boston and faced 34 shots. Carey Price made 21 saves for Montreal.
