BOSTON -- The Boston Bruins had their eight-game winning streak stopped when Jonathan Toews scored in overtime, giving the Chicago Blackhawks a 4-3 victory at TD Garden on Thursday.
The Bruins scored three times in the third period to extend their point streak to 13 games (9-0-4) and remain the only NHL team without a regulation home loss (12-0-5).
Robin Lehner made 37 saves for the Blackhawks (11-12-5), who ended their three-game losing streak.

"Well obviously it's a good feeling. I mean, we knew this was a good challenge for us and a great opportunity," Lehner said. "Been in a little bit of a slump coming in to [play] probably the best team in the League at the moment in their building. Obviously we would like to win in it regulation, but we made some mistakes and they capitalized on it. … They're a good team, we battled hard, made some mistakes, they capitalized on it, and eventually we were rewarded, so it's a great win."
Tuukka Rask made 27 saves for the Bruins (20-3-6), who won their previous three games despite trailing or being tied in the third period.
"I don't know that it's sustainable. Maybe if you can keep it tied and then in the third find that crack and try to expose it. We've got game breakers that can do that," Bruins forward David Backes said. "But certainly digging the hole 2-0, letting them score  seconds into the third, was not a recipe for success.
"That being said, we showed some great character and found a way to get one point out of it, and whatever you say about overtime, they made a play and you know you got all the momentum and you hope to finish off the job of all the hard work to getting that game back to even."
Ryan Carpenter scored a shorthanded goal on a rebound shot at 18:14 of the first period for a 1-0 lead.

Strome, playing for the first time in five games after being out with a concussion, extended the lead to 2-0 on the power play with a tip-in off a shot by Erik Gustafsson at 18:51. Strome had one goal and one assist.
"He was really good I thought, both with and without the puck," Blackhawks coach Jeremy Colliton said.
Alex DeBrincat made it 3-0 with a goal on a snap shot from the left circle 17 seconds into the third period.

Joakim Nordstrom cut the lead to 3-1 at 1:49 when he scored off a rebound of a Backes shot in front.
Chris Wagner's shorthanded goal on a 2-on-1 at 15:01 made it 3-2.
Torey Krug scored from the right side to tie the score 3-3 at 17:27 after Jake DeBrusk passed him the puck from behind the net.
"It was amazing, it was feeling good, too bad we weren't able to pull the two points," Bruins forward David Pastrnak said. "But that's a [heck] of a one point for us. I think the third period, [Par Lindholm] and [Sean] Kuraly's line were unbelievable, and that was a good comeback."

Toews won the game 54 seconds into the extra period on a breakaway from the center line after a Boston turnover.
"I just was able to cause a turnover there," Toews said. "And obviously they had three guys jumping trying to score a goal, and I was able to get a breakaway so it was nice to get that opportunity and capitalize on it."

"We had the start we needed tonight and carried it through 60 for the most part. It's got to be a confidence builder when you beat a team like Boston in their own building, but what matters is what you do next." -- Blackhawks captain Jonathan Toews
"Our job is to make sure we don't get complacent. I don't think we have been, to be honest with you. I think it would show in our record if we were. But, lack of urgency from period to period, absolutely. We're going to continue to address it, but to get to your level 82 times a [year] for 60 [minutes] … it is a challenge for a coach, and it's a challenge for the players, but we'll need it." -- Bruins coach Bruce Cassidy
