The Lightning collected their sixth-straight win on Saturday, defeating the Senators 5-3 at the Canadian Tire Centre.
Tampa Bay entered the third period trailing by one but rallied with three unanswered goals to close the game and extend their season-high winning streak.
After a scoreless opening period, Ottawa emerged with a 3-2 lead after a back-and-forth second frame.
Chris Tierney opened the scoring with a shorthanded goal 46 seconds into the second period. Tierney tried to pass the puck on a two-on-one break but the puck deflected off Victor Hedman's stick and past Curtis McElhinney.

Tampa Bay stormed back to take the lead on a pair of goals from Carter Verhaeghe and Kevin Shattenrkirk just over a minute apart. A nice passing play between Yanni Gourde and Hedman left an open net for Verhaeghe to score and tie the game at one. 65 seconds later, Shattenkirk fired a shot past Craig Anderson after the puck fell to him on a broken play.
The Senators retook the lead with nine seconds to play in the period on a power play goal. Mark Borowiecki scored through traffic with a shot from the point to put Ottawa up 3-2 through 40 minutes.
Brayden Point scored midway through the third period to tie the game at three. Mikhail Sergachev entered the offensive zone with speed and found Point at the left circle who stopped on a dime and fired home a quick shot.
With 90 seconds to play in regulation, Tyler Johnson netted the game-winner. Johnson had his stick on the ice in the slot and redirected a pass from Hedman past Anderson.

Alex Killorn added an empty net goal late in the third to put the game out of reach.
Tampa Bay enjoyed production up and down the lineup with 10 different players recording points. Hedman was the only player to register multiple points, picking up a pair of assists.
Getting the call in the first half of a back-to-back, McElhinney deliverd a solid performance. He finished the night with 25 stops and made some key saves to keep the Lightning in the game as Ottawa applied heavy pressure much of the second period.
The Lightning will look to continue the winning streak on Sunday evening in Raleigh against the Hurricanes.
