TAMPA, Fla. (AP) Milan Michalek surpassed the 30-goal mark for the first time in his career in an unusual way.

Michalek scored three third-period goals, helping the Ottawa Senators withstand a Tampa Bay comeback attempt and beat the Lightning 7-3 on Tuesday night.

Ottawa, which took a three-goal lead early on, went up 5-3 when Michalek scored a power-play goal at 12:12 of third. The left wing added two empty-net goals, including a short-handed effort with 7 seconds left to give him a career-best 32 goals this season.

``That's great for him,'' Senators coach Paul MacLean said. ``I think he's always been a player of that potential and the injuries that he's had kind of slowed him down. We're really happy for him. To reach that plateau, it's really a credit to him and his hard work.''

Michalek's previous high for goals was 26, set while with San Jose in 2006-07. He also had a hat trick against Tampa Bay on Oct. 15, 2009.

Tampa Bay got within 4-3 when Steven Stamkos scored his league-leading 48th goal of the season during a power play at 5:41 of the third. The center has five goals and three assists during a five-game point streak.

Sergei Gonchar, Colin Greening, Kyle Turris and Erik Karlsson had the other Ottawa goals. Michalek also had an assist, setting up Greening's goal with a nifty pass from behind the net.

Senators defenseman Chris Phillips left in the first with a broken nose after a center-ice hit.

``Right now, it's open to evaluation,'' MacLean said. ``He had to get it reset. We'll just to see how he gets through it.''

Ryan Shannon and Tim Wallace also scored for the Lightning, who had won four in a row. Teddy Purcell assisted on Stamkos' goal and has 14 assists and 20 points during a career-high 10-game point streak.

Tampa Bay goalie Mathieu Garon left four minutes into the game with an undisclosed lower body injury after making a save and was replaced by Dwayne Roloson. Garon, who had gone 12-3-2 in his previous 17 starts, appeared to get hurt when he kicked out his leg on the play.

Lightning coach Guy Boucher said Garon will have an MRI on Wednesday.

``He's been playing well for us,'' Stamkos said. ``It was tough.''

Greening and Turris scored 53 seconds apart late in the first as Ottawa took a 3-0 lead. Greening scored from the low slot, while Turris' shot went off Tampa Bay defenseman Brett Clark.

Gonchar stopped a personal 43-game goal drought, dating back to Nov. 12 against Toronto, to put Senators up 1-0 midway through the first.

The Lightning got within 3-2 in the opening 7:12 of the second when Shannon and Wallace scored on 6-foot-7 Ben Bishop, who was making his Senators debut. Bishop was acquired from St. Louis for a 2013 second-round draft pick on Feb. 26.

``When they score seven goals, it helps,'' said Bishop, who made 25 saves. ``The guys played good in front of me.''

Karlsson made it 4-2 on a power-play goal at 11:58 of the second. The defenseman has 16 goals and 67 points this season.

The Senators won the season series 4-0, outscoring Tampa Bay 19-6.

``We can't seem to beat those guys,'' Boucher said.

Ottawa is without goalie Craig Anderson, who is sidelined by a hand injury. He won all three of the Senators' previous games this season with the Lightning, allowing just three goals overall.

The NHL fined Karlsson $2,500 for slashing Florida's Sean Bergenheim during a game on Sunday. ... Tampa Bay D Victor Hedman was in the lineup after missing four games due to an upper body injury. ... In 10 games against Tampa Bay, Anderson is 6-1-2 with three shutouts and an 1.24 goals-against-average. ... Lightning D Marc-Andre Bergeron is scheduled to have back surgery on Wednesday. ...
