OTTAWA - Stephen Weiss scored 4:50 into overtime as the Florida Panthers downed the Ottawa Senators 4-3 at Scotiabank Place.
Following a Senators turnover, Weiss moved in across the Senators blue-line and took a shot that deflected off the outstretched stick of defenceman Chris Phillips and past netminder Alex Auld.
Nick Boynton, Michal Repik and Jay Bouwmeester also scored for the Panthers (12-12-3) while Craig Anderson made 35 saves for the win.
Chris Kelly, Dany Heatley and Jason Spezza replied for the Senators (10-11-4), who blew three one-goal leads. Auld made 36 saves in defeat.
The teams entered the third period tied 3-3 following a four-goal outburst in the second period. The Senators took leads of 2-1 and 3-2, but the Panthers scored to tie the game in quick succession both times.
Heatley scored at 2:32 of the second when his shot from the right face-off circle went through Anderson's legs, but Repik scored his first career goal at 3:52 to tie the game. Repik was playing his first game in the NHL after being recalled from the Panthers' AHL affiliate in Rochester earlier in the day.
Jason Spezza scored for the fifth time in his past three games after taking a puck off the end boards and stuffing it past Anderson at 8:20, but again the Panthers responded. After a flurry in front of the Senators goal, Bouwmeester moved in from the point and beat Auld with a shot from the slot at 9:58, just 21 seconds into a power play.
The Senators played the final 91 seconds of the period with a two-man advantage but were unable to get a third go-ahead goal of the period.
Kelly scored his first goal in 15 games to give the Senators a 1-0 lead at 7:31 of the first period. Several players slid over a loose puck in the crease before Kelly lunged forward and knocked it into the back of the net.
The Panthers tied the game at 11:26 when Boynton one-timed a behind-the-net pass from Ville Peltonen past Auld.
