Senators 3, Canadiens 2 (OT): Cory Conacher tied the game with 22.6 seconds remaining in the third period and Kyle Turris scored at 2:32 of overtime as host Ottawa edged second-seeded Montreal to take a 3-1 lead in their Eastern Conference first-round series.
After Conacher forged a 2-2 tie by burying a loose puck at the top of the crease, Turris put the seventh-seeded Senators within one victory of advancing when his rising shot from the top of the left faceoff circle deflected off Canadiens defenseman Raphael Diaz and past Peter Budaj. It was just the second shot faced by Budaj, who started the overtime session after Carey Price (30 saves) suffered an undisclosed injury at the end of the third period.
Mika Zibanejad also scored, Turris added an assist and Craig Anderson stopped 26 shots for Ottawa, which can close out the series when the teams meet in Montreal for Game 5 on Thursday.
Defenseman P.K. Subban and rookie Alex Galchenyuk tallied for the Canadiens, who were outshot 15-5 after the second period.
After a scoreless first session, Montreal built a 2-0 lead as Subban and Galchenyuk scored 62 seconds apart early in the second. Ottawa halved the deficit with 8:05 remaining in the third, as enforcer Chris Neil's pass from along the right-wing boards caromed off the left skate of Zibanejad and past Price.
