UNDATED (AP) — Max Pacioretty and the Montreal Canadiens now find themselves atop the NHL's Eastern Conference standings following a convincing win over a bitter rival.

Pacioretty scored twice and Carey Price needed to make just 21 saves as the Habs hammered Boston 5-1. Dale Wiese (wees) tied the game by scoring on a penalty shot 2 ½ minutes into the second period before Lars Eller notched the game-winner. Eller and Wiese also had one assist apiece for the Canadiens, who improved to 12-4-1.

The Canadiens were able to take over the conference lead when Tampa Bay fell to San Jose 2-1. Joe Thornton and Tyler Kennedy scored second-period goals to support Antti Niemi (AN'-tee nee-EH'-mee), who turned back 32 shots and blanked the Lightning until Steven Stamkos beat him with 10:25 remaining.
