Tucker one-timed a shot over Ray Emery’s left shoulder, the roof nearly blowing off Air Canada Centre as the Leafs erased a pair of two-goal deficits to earn two huge points as they kept pace in the Eastern Conference playoff chase. The Leafs moved into a tie for the eighth and final playoff spot with Carolina at 75 points.
Nik Antropov and Boyd Devereaux had third-period goals for the Leafs (33-27-9), who deserved the victory after outshooting the visitors 45-22 and clearly outchancing them.
But Emery was fantastic, losing for only the first time this season after facing 40 or more shots (6-0-1).
Daniel Alfredsson, Mike Fisher and Dany Heatley scored for the Senators (39-23-7), who still won the season series 5-1-2.
Alfredsson opened the scoring at 14:06 of the first period, slipping in a rebound after the Leafs had enjoyed most of the scoring chances. The Senators captain then set up Fisher for a pretty power-play goal 8:01 into the second period, with Fisher beating Andrew with a one-timer from the slot.
Tucker got his team back into the game with Toronto on a two-man advantage, finishing off a cross-ice pass from Sundin from his usual spot.
Heatley, short-handed, quieted the crowd of 19,527 at the ACC with a one-time blast from the top of the faceoff circle after a clean faceoff win by Jason Spezza over John Pohl. But what would have normally been a back-breaking goal with only 55 seconds left in the middle period was not.
The Leafs, however, didn’t play like their spirits were broken, continuing to hustle in the third period before Devereaux broke through at 9:09, his wrist shot beating Emery through a screen.
Then Antropov tied it on a strange goal with 4:02 left in the third period, somehow knocking in his own rebound past Emery, setting up Tucker’s overtime heroics.
The game marked the return of Leafs forward Kyle Wellwood, who missed 33 games with a sports hernia.
