The Sens erased a four-goal deficit to storm back to beat the Toronto Maple Leafs 6-5 in overtime Monday night at Scotiabank Arena.
"In hockey, anything can happen," Evgenii Dadonov said. "We didn't stop playing. We went shift by shift and goal by goal."
Dadonov tied the game with 2:01 to play with a fantastic swat of the puck out of the air with the goalie pulled before burying the overtime winner on a breakaway at 2:19.
"We've won two games in a row and it's given us some belief we can play," Dadonov said.
The Sens (4-13-1) also had goals from Drake Batherson, Nicholas Paul, Artem Zub and Connor Brown while Marcus Hogberg made 33 saves for his second straight win.
Toronto (11-3-2) got goals from Auston Matthews (2), Travis Boyd, Pierre Engvall and Joe Thornton while Frederik Andersen stopped 25 shots.
It was the first time in franchise history that the Senators had overcome a four-goal deficit.
"We got in the room and we were so fired up," Batherson said. "Comebacks like that are the best wins and I'm so happy for the boys."
The Maple Leafs had built a 5-1 lead through essentially two periods of play. Matthews opened the scoring 6:32 in before Boyd doubled the lead at 10:29.
Ottawa got some life through Batherson's second of the year at 12:40 as he beat Andersen short-side with a backhander but the Maple Leafs rattled off three straight goals in the third to open the game up.
Engvall's first of the season came 1:49 into the second before a returning Thornton scored at 9:51. Matthews' second of the night came with 59 seconds left in the period as he was left all alone out front on a 5-on-3 power play.
But the Sens found life with just nine seconds left in the period as Paul scored the first shorty of the year as he buried a rebound after Austin Watson had originally been denied by Andersen.
"The short-handed goal was huge going into the intermission," Batherson said. "The guys told us during the second intermission to keep going and that anything can happen and we showed it there."
And just 41 seconds into the third period, the Sens really began to roll. As he stepped out of the penalty box, Zub took a pass from Brown and impressively went forehand, backhand, and back to his forehand to slide the puck past Andersen for his first career NHL goal.
"I'm incredibly happy," Zub said.
Brown's third of the year at 5:52 cut the deficit to 5-4 as he worked a lovely passing play with Colin White before Dadonov's heroics gave the Sens the two points.
"It was a great win," Batherson simply summed up.
