Brandon Hagel scored on a breakaway 1:19 into overtime as the Tampa Bay Lightning took down the NHL's top club, topping the visiting Boston Bruins 5-4 on Monday night.

After Tampa Bay won the overtime faceoff and kept possession for the entire three-on-three session, Victor Hedman found Hagel on a breakaway off a line change.

Hagel slipped his ninth goal of the season through the legs of goaltender Jeremy Swayman (41 saves) as the Lightning won for the first time in five overtime games.

Hagel and Steven Stamkos each had a goal and an assist, while Tanner Jeannot, Nicholas Paul and Austin Watson scored to help Tampa Bay improve to 6-2-2 at home and win its third straight game. Goalie Jonas Johansson stopped 23 shots.

David Pastrnak recorded a goal and an assist, and Pavel Zacha, Charlie Coyle and John Beecher each scored for the Bruins, who dropped to 7-1-2 in their past 10 games and are 2-3 in overtime.

To open the second game on their three-game homestand, the Lightning went up 1-0 on a delayed penalty, as Jeannot scored his fourth goal at 6:39.

However, the visitors scored the equalizer off a turnover when Pastrnak skated in and reversed a pass to Zacha, who deposited his seventh goal at 9:55.

During a testy second period that resulted in three of the six minor penalties being for roughing, the Lightning had a five-on-three and four-on-three power play.

Paul put his club up 2-1 when he deflected in a wide shot from Mikhail Sergachev with 30 seconds remaining in the frame.

Starting the third trailing for just the second time in 17 games, the Bruins evened it at 2-all when Pastrnak blistered his 12th goal from way above the left circle at 6:26, then the club quickly took its first lead.

It kept the puck in the offensive zone, and the puck found its way to Beecher, who slipped his second tally by Johansson just 81 seconds after Pastrnak's goal.

For his first point of the season, Watson flipped in the game-tying goal from the bottom of the right circle less than a minute later.

James van Riemsdyk won a battle behind the Lightning goal and put the puck on Coyle's stick for his sixth tally at 16:09.

However, Stamkos' seventh marker tied it with 4.8 seconds left to send the match to overtime.
