Senators 3, Lightning 2, OT

OTTAWA - Jason Spezza scored a power-play goal 4:17 into overtime to give the Ottawa Senators a 3-2 victory over the Tampa Bay Lightning on Thursday night.

Spezza, sidelined the previous two games because of back pain, drove a slap shot past Antero Niittymaki after Tampa Bay's Mattias Ohlund was sent off for holding three minutes into overtime. Spezza also assisted on Daniel Alfredsson's first-period goal, but his first tally of the season couldn't have been more timely.

"It felt good to get it in overtime and get the win," Spezza said afterward. "And to get my first one was nice. I felt pretty good about my game going into tonight. I just wasn't getting any bounces, so it was nice to finally get one."

Mike Fisher also scored for Ottawa (7-4-2) and Pascal Leclaire made 18 saves in the third meeting between the two teams this season, the second in seven days.

Alex Tanguay and Steven Stamkos scored power-play goals for Tampa Bay (5-4-5). The Lightning are 1-1-1 on a four-game trip that included a 2-1 overtime win in Toronto on Tuesday night. Stamkos has 12 goals this season.

Niittymaki stopped 26 shots in his second start in a row.

Stamkos drew the Lightning even at 2-2 when he drove a slap shot past Leclaire 13:40 into the second for Tampa Bay's second power-play goal of the game.

Referee Kerry Fraser waved off a pair of Ottawa goals with under five minutes remaining in the third, including Chris Kelly's high-stick tip with 26.8 seconds left.

A brief video review confirmed Fraser's call.

The official drew the ire of the Scotiabank Place crowd moments earlier when he waved off another apparent go-ahead goal by the Senators with 4:09 remaining.

Fraser ruled that the Lightning gained possession while a delayed penalty was signalled against Tampa Bay's Andrej Meszaros before Filip Kuba put a backhand past Niittymaki. 

Tanguay gave the Lightning a 1-0 lead 3:03 in with his second of the season.

Alfredsson drew Ottawa even just under two minutes later with his sixth goal.

Fisher scored on a power play 12 minutes into the second to give the Senators a brief 2-1 lead.
