Anthony Cirelli scored with 13 seconds remaining in overtime to lift the Bolts to a 4-3 win over the Senators on Tuesday night.
The goal put a positive finish on what was an up and down night for the Lightning.
The Bolts took advantage of a mistake from Ottawa goaltender Marcus Hoberg to open the scoring. The Senators appeared to be on the way out of their zone but Nikita Kucherov stepped in to force a turnover and fired a shot past Hoberg who was looking for his misplaced stick after chaos in the crease moments prior caused it to go flying.

The lead would last only a few minutes as Mark Borowiecki scored with a blistering shot from the point that beat Andrei Vasilevskiy through traffic to tie the game.
Tampa Bay managed to take a lead into the first intermission after Cedric Paquette scored late in the period. Yanni Gourde found Paquette wide open in the slot and he wired a shot past Hoberg to put the Lightning up 2-1.
The Lightning appeared to be in control after Brayden Point scored less than four minutes into the second period on a wrist shot from the right circle but the Senators answered back with a pair of goals to tie the game at three through 40 minutes.
Connor Brown scored Ottawa's second goal just 29 seconds after Point's tally and Anthony Duclair scored on a breakaway late in the period, capitalizing on a turnover from Kucherov at the offensive blueline.
After a scoreless third period, the Lightning controlled play for most of overtime.
Anthony Cirelli scored the game-winner after he split the Ottawa defense and scored on a breakaway with only 13 seconds remaining. Cirelli ended up crashing into Hoberg but the puck crossed the line before the net came dislodged to give the Lightning both points.
Point was the only Bolts to finish with multiple points, picking up a goal and the assist on Cirelli's goal in overtime. Vasilevskiy finished the night with 25 saves on the 28 shots faced.

The Bolts got good news on the injury front on Tuesday night with both Tyler Johnson and Kucherov dressing. Johnson hadn't played since suffering a lower-body injury earlier this month and Kucherov was a game-time decision after leaving Saturday's game with a lower-body injury.
The Lightning return to Amalie Arena on Thursday to host the Stars in the finale of a four-game homestand.
