OTTAWA -- Jason Spezza is glad he won't have to answer any more questions about his early goal drought.
Sidelined the previous two games because of back pain, Spezza drove a slap shot past Antero Niittymaki for his third point of the game after Tampa Bay's Mattias Ohlund was sent off for holding 3 minutes into overtime.
"I felt pretty good about my game going into tonight and I just wasn't getting many bounces," said Spezza, a 30-goal scorer each of the last three seasons. "It's nice to get one, though, to get the monkey off a little bit."
Spezza also assisted on goals by Daniel Alfredsson and Mike Fisher.
"He's a big part of our team," said Pascal Leclaire, who made 18 saves. "He's a presence. When he has the puck he can do so many things. He makes the defense back up a little bit and keeps them thinking so obviously you want him on your team and he played great tonight."
Ottawa (7-4-2) won for the second time in three meetings between the two teams this season, including a 5-2 loss in Tampa Bay one week earlier.
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.
"Obviously we wanted to win but I think it was a good game," Lecavalier said. "It was a little bit like the game in Toronto, high intensity, and both teams had their chances and the goalies played well. I think it was a good game overall."
Rookie Lightning defenseman Victor Hedman left the game in the second and did not return after he was leveled by Ottawa's Chris Neil on a hit along the boards behind Tampa Bay's net.
"I saw it kind of quickly on the board," Lecavalier said. "A couple of guys said it was dirty but I don't want to comment on it. I didn't see it clearly."
Steve Downie was assessed an instigating minor, a major and a misconduct at 14:12 when he came to his teammate's defense and fought Neil, who wasn't surprised by Downie's reaction.
"You don't like to see your teammates get hit like that but it's a clean hit, sometimes you can't do much about it," Neil said.
Stamkos drew the Lightning even at 2 when he drove a slap shot past Pascal 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 5 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 signaled 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 2 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.
