TAMPA -- Brad Marchand scored 10 seconds into overtime, and Jonas Gustavsson made 42 saves to help the Boston Bruins to a 1-0 win against the Tampa Bay Lightning at Amalie Arena on Tuesday.
Marchand scored his 34th goal on a 2-on-1 rush with Patrice Bergeron, who made a perfect pass to Marchand in the slot for a one-timer that beat Lightning goalie Ben Bishop to the stick side.
"Anytime you have a game like that, a tight-checking game, back-and-forth, it was big to win that," Marchand said. "We're battling for position right now. [Gustavsson] played incredible. We wouldn't have won if he didn't play the way he did. He kept us in it with some big saves."
Boston (38-23-7) is tied with Tampa Bay for first place in the Atlantic Division at 83 points; the Lightning have played one fewer game and have two more regulation and overtime wins (36-34).

It was Gustavsson's first shutout this season and the 7th of his NHL career.
"We wanted to bounce back from last night (a 5-4 overtime win against the Florida Panthers), especially defensively, and I thought we did that," Bergeron said. "We gave a lot of shots, but most of them were from the outside. It's great to the see the results of the hard work. We have some more work to do, but at the same time, we're seeing some great things happening."
Bishop made 32 saves for the Lightning (39-23-5), who have lost two games in a row after winning nine straight, the longest streak in their history.
After Boston had an 11-8 advantage in the first period, the Lightning outshot the Bruins 34-21 in the second and third.

"We had a little bit of a flat first period," Lightning coach Jon Cooper said. "But I thought we responded really well in the final two periods. We were putting good pressure on, we got a little unlucky on the iron a couple of times, but both goalies were outstanding. It was going to take a really nice goal to win this game."
Gustavsson, in his first start since Feb. 22, made his best save in the second period, when he robbed Alex Killorn with his glove on a redirected shot.
"I thought we had a good first period, the second period we were on our heels a little bit," Bruins coach Claude Julien said. "But our patience paid off and we found a way to score that goal."

Bishop also made some tough saves in the second period, including a stop on a redirect from Landon Ferraro and a save on Loui Eriksson from the slot near the end of the period after Eriksson skated past the Lightning defense.
"That was a big point with both teams playing back-to-back," Bishop said. "Obviously, you'd like to get the two points, but right now we'll take one. Two teams fighting for first place, it had a little bit of a playoff atmosphere."
Lightning defenseman Anton Stralman missed the game with an undisclosed injury. It was the first game he has missed since signing with Tampa Bay as a free agent July 1, 2014.
