BOSTON -- Dallas Stars forward Tyler Seguin scored his seventh NHL hat trick, including two of the Stars' three power-play goals, in a 5-3 victory against the Boston Bruins at TD Garden on Tuesday.
Seguin, who was traded by the Bruins to the Stars on July 4, 2013, had no points in his previous two games with Dallas here. Seguin extended his point streak to six games and got his 300th NHL point.
"Yeah, I mean, it feels good. It feels good to win in here; it's a tough building to win [in]," Seguin said. "It always feels good to score, and obviously I'm very happy with how we responded after playing a bad game in Toronto [on Tuesday] night."
Defensemen Alex Goligoski and Jyrki Jokipakka scored for Dallas (10-3-0), which has won four of its past five games. John Klingberg, Jamie Benn and Jason Spezza each had two assists, and goaltender Kari Lehtonen made 36 saves.
Boston (6-4-1) had its seven-game point streak end (6-0-1). Loui Eriksson, who was part of the Seguin trade, scored twice, and Tuukka Rask made 14 saves.
"There were a lot of problems tonight," Bruins coach Claude Julien said. "First period I didn't mind, and second period and third period I don't know where our team went. We just kind of lost our focus and we weren't the same team again. Instead of trying to dig it in, I think the way they were playing us, our guys were getting more and more frustrated, and the more we got frustrated, the more we got away from our game. It's a lesson learned for our guys, and with a tough road trip coming up, we just made it even harder."
Bruins forward Chris Kelly fractured his femur 1:40 into the game; he will have surgery Wednesday and is expected to be out 6-8 months. The Bruins found out quickly they are going to miss the versatile veteran.
"Him being out that long, where he's such a good guy at pulling guys aside and he always plays the right way, always makes the right play," Bruins forward Brad Marchand said. "Having him not there in the room to talk to us about certain things and stepping up where we need it, where after the second period, he would've been the guy to say something. So it's times like that we're going to miss him."
Boston had the first seven shots on goal. But Seguin scored on the first Dallas shot of the game with a wrist shot from the left circle for a 1-0 lead at 5:46.
The Bruins made it 1-1 on a Colin Miller shot that beat Lehtonen low to the stick side for Miller's first NHL goal at 7:14.
Boston took a 2-1 lead on a power play; Eriksson flipped in a rebound of a Torey Krug shot with 24.1 seconds remaining.
Seguin scored his second goal and tied the game 2-2 during a Dallas power play in the second period. He beat Rask with a slap shot from the top of the left circle at 4:37.
Jokipakka put the Stars ahead 3-2 with a slap shot from the left point that eluded a screen by Radek Faksa at 17:18. It was Jokipakka's first NHL goal.
Seguin completed his hat trick on another Dallas power play by beating Rask with a one-timer from below the left faceoff dot for a 4-2 lead at 1:18 of the third period.
Goligoski scored a power-play goal at 9:13 for a 5-2 lead. Eriksson's second goal made it 5-3 with 2:15 remaining.
Dallas lost the first game of its four-game Eastern Conference road trip 4-1 to the Toronto Maple Leafs on Monday. So it was important to the Stars that they bounced back.
"Yeah, that was the message coming into this game, and we didn't have the best effort there in Toronto," Benn said. "And I thought we responded well as a team. Even though they probably doubled us in shots, I thought we played a much better game on the defensive side."
The Bruins were without forward David Pastrnak because of a bruised foot. The Stars were without forward Ales Hemsky because of a hip injury.
The Dallas road trip continues against the Carolina Hurricanes on Friday. Boston next plays at the Washington Capitals on Thursday.
