The Sens remain two points back of the Penguins, Red Wings and Bruins. All four clubs have three games remaining.
With Ottawa’s loss, the Washington Capitals have clinched a berth in the playoffs.
Joffrey Lupul opened the scoring at 3:10 of the first.
After Erik Karlsson scored his 21st of the season to tie it 1-1, James van Riemsdyk gave Toronto a 2-1 lead.
Karlsson becomes the first Senators defenseman in franchise history to record 21 goals in a single season. With his assist on the goal, Kyle Turris established a new career high for points in a season (59).
Mark Stone netted his 22nd of the season 1:09 into the third to force overtime.
#Sens coach Dave Cameron: "We're clawed, we're clawed. We're still alive."
Interim head coach Peter Horachek chose to bench Lupul during the Leafs’ 4-3 shootout victory over the Buffalo Sabres.
Lupul, who has just two assists and no goals in 16 games, had a costly turnover in the second period, which led to the Sabres’ second goal of the game.
Lupul played the final 1:32 of the second period, but watched the first 12:09 of the third period and did not play in overtime.
“I think Joffrey turned the puck over a few times and he let the guy go on the back-check going back to the net, gave him a chance,” said Horachek outlining the reasons for Lupul’s benching. “The guy could’ve scored, he basically shot it wide and hit the side of the net.
“There was two, three, four things that I didn’t think was up to his standards. Tonight I didn’t think that he was on top of his game.”
Lupul was dropped from his line alongside Peter Holland and Richard Panik to the fourth line. David Booth replaced Lupul on Toronto’s second power play unit.
Lupul, who averaged 15:44 in ice time this season entering Wednesday’s game, finished with 13:09 in time on ice.
David Booth, who was once a 30-goal scorer in the NHL but then endured a number of different injuries and a buyout last summer, finally scored his second goal of the season on Thursday.
You know what? It was actually quite a nice goal, too. It ends a scoring drought at 31 games for the winger.
Booth forced the turnover in the neutral zone, and seconds later he buried a Peter Holland pass top corner, over the shoulder of Ben Bishop. Booth last scored on Dec. 16 against the Anaheim Ducks. That goal also counted as the winner.
With the All-Star Game in the books, Leafs coach Peter Horachek revealed that Dion Phaneuf is week-to-week with an upper-body injury sustained prior to the break.
Toronto didn’t provide further details on his condition, but he reportedly aggravated an existing hand injury while fighting Carolina’s Eric Staal on Jan. 19 and then made his condition worse versus Ottawa on Jan. 21, according to TSN’s Darren Dreger.
If you missed the Hurricanes and Leafs’ captains spar, you can see it below:
He also fought Milan Michalek in the Ottawa game:
Toronto has endured a horrendous 3-14-0 stretch that has added fuel to the speculation that the Maple Leafs might attempt to revamp their core.
Joffrey Lupul and Peter Holland remain day-to-day, but on a more positive note Leo Komarov should be back Wednesday, per the team’s Twitter feed.
