After being unable to score on three breakaway chances during the final two minutes of regulation and into overtime, the Senators finally buried the game-winning goal through Brady Tkachuk to beat the Montreal Canadiens 3-2.
"They were out there for a while and it was a great job by the lines before," Tkachuk said. "I tried making a backdoor play but just a lucky bounce and just tried to quickly get it on net and luckily it went in."
Drake Batherson missed a breakaway with less than 100 seconds left in regulation while Connor Brown and then Tkachuk weren't able to bury their own chances all alone in the extra frame.
But Tkachuk wouldn't waste his second opportunity as he buried a puck out front after banking it off the skate of Alexander Romanov at 3:30 of overtime for his sixth goal of the year.
"We don't want to get it to just overtime, we want to win," Tkachuk said. "We want to win whether it's in regulation or overtime. We want to keep attacking and keep creating chances and taking advantage of the chances we have.
"That was the mentality we had and I think it was a great moment for our group to get success from that mentality and we're going to use that moving forward."
Batherson and Josh Norris had goals in regulation for Ottawa (5-14-1) while Matt Murray made 30 saves. Nick Suzuki and Corey Perry scored for the Canadiens (9-5-3) while Jake Allen turned away 36 shots.
Montreal grabbed a 1-0 lead 1:17 in on Suzuki's fourth of the season but the Senators got out of the period all square as Batherson drove the net and lost the puck but it hit Romanov's stick and flipped over Allen and into the net at 9:47.
After a scoreless second, Ottawa had the lead 3:33 into the third on another fortunate bounce. Norris tipped Nikita Zaitsev's point shot and it hit the stick of Allen and again went over his head before rolling in as the Sens rookie collected his fourth goal of the year.
Montreal tied the game with 5:25 to play on Perry's second of the season.
"Our mentality in overtime was let's win this thing," Sens head coach D.J. Smith said. "Let's not sit back and certainly we did that … I thought we were attacking and I thought we were dangerous."
The Senators kept the Montreal power play quiet, killing off all three of their opportunities. On the flip side, the Sens were unable to score a power play goal yet again as they went 0-for-4.
Sens d-man Thomas Chabot did not play, missing his second straight game. Forward Evgenii Dadonov played in his 300th career NHL game.
The two teams meet again Tuesday night.
