The Boston Bruins clinched the Presidents' Trophy on Thursday but quickly turned their focus towards the postseason, with coach Jim Montgomery "looking forward to that grind".

The Bruins have been the NHL's outstanding team this season and moved to 121 points – out of the reach of any rival – with a 2-1 overtime win against the Columbus Blue Jackets.

Their 58th win of the campaign set a new team record, but Montgomery is keen to ensure this is not the extent of their achievements.

After a victory that he acknowledged was "not the standard we've seen all year", he said: "We're not at our game, and there's fatigue that comes in. It's not easy, but we're finding ways to win.

"It's been a magical season so far, and we know the hardest part is ahead of us, and we're looking forward to that grind."

Bruins captain Patrice Bergeron was slightly more interested in revelling in their Presidents' Trophy success, the fourth in team history.

"Of course you're proud," he said. "A lot of games and a lot of hard work.

"I'm proud of the way we've done it, sticking to our process and growing as a team."

The Bruins have seven games left in the regular season and need five more wins to set a new NHL record for wins in a single season.

Boston Bruins coach Jim Montgomery hailed his side for rising to the challenge of a tough schedule to beat the Montreal Canadiens.

A 4-2 win at TD Garden marked a fifth consecutive victory for the Bruins and saw the team hit the 55-win mark, their second-highest all-time total behind only the 57 wins secured by the 1970-71 side.

The Bruins' fine run has highlighted their resilience, having endured a two-game skid prior to their current streak, with no side in the NHL currently having a longer win streak.

Having already secured their playoff berth, the Bruins are looking to maintain their momentum heading into the postseason and Montgomery was delighted by the result, though admitting his team were not at their best.

"Happy that we got the two points. It's a tough league to win in," he told reporters after Thursday's win. "I know we've won a lot this year, but it really is.

"With the schedule as challenging as it is right now – we're playing four games a week, and it's four in six nights consecutively for five weeks – we're not going to have the most energy we usually do have.

"I don't think we skated very well tonight, but it's understandable at times. You've got to give credit to those guys. We find a way to win hockey games.

"It's not an easy league to win in, and we find ways to do it. That's the positive side of things."

David Pastrnak was again on form for the Bruins, hitting his 49th goal of the season to represent his best campaign and tie him with Ken Hodge for eighth-highest scorer all-time for the Bruins with 289.

The 26-year-old was not focused on his display, however, and simply enjoyed the rivalry clash against the Canadiens.

"This is the kind of game where the only thing you think about is getting the win," Pastrnak said.

"These games against Montreal never get old. It doesn't really matter where in the standings each team is. It brings so much history.JI

"It's a big win. When Montreal and the Bruins play, both teams are gonna play hard."

Boston Bruins coach Jim Montgomery has learned to normalise the success of his team this season, even as they made NHL history on Thursday.

In beating the Buffalo Sabres 7-1, the Bruins improved to 48-8-5 and 101 points for the year.

The Bruins passed 100 points in their 61st game, beating the previous record set by the 1976-77 Montreal Canadiens, who reached that mark in 62 games.

But Montgomery was relatively unmoved by the achievement, having grown used to his brilliant team setting the benchmark over the course of the campaign.

"For me personally, it doesn't mean that much," the Boston coach said. "We try to stay in the moment, and we've been doing that.

"We started off 11-1, and I was like, 'man, that's unreal,' and then you catch yourself and you go back into the moment, and we've probably gone 11-1 every 12 games to have the record we have.

"It's been really amazing to watch them want to be great, because with the schedule and everything, it's really impressive."

The latest win came on an eventful day for the Bruins, who tied David Pastrnak to an eight-year, $90million extension earlier on Thursday.

Pastrnak then had a goal and two assists against the Sabres just hours later.

The Bruins also traded for forward Tyler Bertuzzi from the Detroit Red Wings ahead of Friday's deadline.

Boston Bruins winger Brad Marchand says they could not "care less about any regular-season records" as hype swirls about breaking the long-standing NHL points record.

The NHL-leading Bruins possess a 43-8-5 record through 56 games, putting them on track for 133 points which would eclipse the record during an 80-game season of 132 points set by the Montreal Canadiens in 1976-77.

Boston are also on pace for 63 wins which would surpass the single-season record of 62 victories held by both the 1995-96 Detroit Red Wings and the 2018-19 Tampa Bay Lightning.

But Marchand downplayed the significance of those milestones within the playing group who were focused on bigger targets.

"People have talked a lot about some of these records, that we could potentially hit or we have hit," Marchand told ESPN.

"Nobody cares about those in this room. We couldn't care less about any of these regular-season records because they really don't mean anything.

"Before we were going through this season, if you asked any of the guys on this team who owned any of those records, nobody would know, because nobody cares, because it's not about the regular season.

"As soon as somebody brings it up, it's in one ear and out the other."

Marchand added that lifting the Stanley Cup was the goal, rather than records or finishing atop the standings after the regular season.

"If you win the Presidents' Trophy but you don't win the Cup, nobody cares," he said. "That's what we know on this team."

David Pastrnak became the fifth Bruins player to score 40 goals in consecutive seasons as the Bruins remained on pace for a history-making season with Monday's 3-1 win over the Ottawa Senators.

Pastrnak scored twice, breaking the second-period tie to move beyond the 40-goal mark for the third time in his career.

The win improved the NHL-best Bruins' record to 43-8-5, extending their current win streak to four games.

Boston are currently on pace for 62 wins, which would match the record held by the 1995-96 Detroit Red Wings and the 2018-19 Tampa Bay Lightning.

The Bruins are also on pace for 133 points, which would exceed the record held by the 1976-77 Montreal Canadiens.

Boston also tied the 1979-80 Philadelphia Flyers for the fewest games to reach 90 points in NHL history.

Bruins center David Krejci, who brought up his 1000th game, said the challenge for the team was to not mentally let standards slip.

"We're at that point in the season where it's mental," Krejci told reporters. "We all know what we can do in this room, and we've got to be mentally prepared for each game.

"We hit a little tough patch maybe a couple of weeks ago, but we're a good team. We've got good guys on the team, and we talk about it.

"Like I said, it's mental. We've just got to get ready for those games. We've got to stay sharp because it is not easy.

"This is the time of the year that if you let up, it can get away from you pretty easily, so we've got to stick together, grind it out and be mentally sharp."

Boston Bruins head coach Jim Montgomery hailed his side's ability to overcome adversity after rallying for a 3-2 overtime win against the Dallas Stars on Tuesday.

The NHL-leading Bruins improved to a 40-8-5 record with the victory where Pavel Zacha tied the game at 2-2 at 10:12 of the third period, before David Pastrnak fired a one-time finish home from Charlie McEvoy's cross-ice pass with 1:16 remaining in overtime.

Pastrnak's goal came after the Bruins had killed off a Dallas OT power play, thanks to five Linus Ullmark saves, to get the better of the Stars, who lead the Western Conference.

Dallas had fought back from an early deficit from Taylor Hall's strike to lead 2-1 after goals from Roope Hintz and Jason Robertson, before the Bruins rallied. The Stars also failed to capitalise on a five-on-three power play in the second period.

"It was nice to win a game where we had to overcome so many struggles within the game," Montgomery told reporters.

"The penalty kills, then playing really well and not having the lead, trailing. Keep pushing, keep believing.

"There's a lot of belief in that locker room if we play the right way. We have a lot of depth that can overcome a lot of adversity."

The win was Montgomery's 100th in the NHL, including 60 in charge of the Stars before being fired in December 2019. This game marked his first in Dallas as a head coach since that dismissal.

Zacha, who finished the game with a goal and an assist, praised his side's identity.

"That's what our team is about, our identity," he said. "With having the leaders like we do I don't think we get frustrated. We just get to working hard, sticking to the process.

"I think that's one of the game's best third-period teams, so we know our strength."

Sebastian Aho has taken his game to a new level after inspiring the Carolina Hurricanes to a 4-1 victory over the NHL-best Boston Bruins on Sunday.

That is the assessment of team-mate Brent Burns, who is enjoying a first-hand view of the flying Finn's excellent form.

Aho scored for a fourth game running, while Paul Stastny, Seth Jarvis and Jordan Staal each finished with goals as the Canes made it five straight wins to sit top of the Metropolitan Division in the Eastern Conference.

"It's been fun. It's fun to see a guy like that off the ice, what he does and how competitive he is on the ice," Burns said of Aho.

"He doesn't like to lose in anything. It's fun to see it up close and take it to the next level.

"He's just explosive when he gets the puck. Anybody can see his confidence growing and he's just a special player. It's special to see every day."

Aho has racked up seven goals during his streak, and has 21 overall for the season.

"He seems to have picked that step up again," Canes head coach Rod Brind'Amour said. "He's playing at a high level, that's for sure."

Pavel Zacha managed the solitary goal for a Bruins side who have 81 points, the most in the NHL, but are now on a three-match losing streak.

Nonetheless, Aho recognised the quality at Boston's disposal.

"Through the lineup, every line did their job. That's a great team we played tonight," Aho said.

"There's a reason why they're at the top of the standings. They play a good game. We needed to bring our best tonight."

Brind'Amour added: "It was a great game. Listen, we know that that team is the cream of the crop and they're lapping everybody right now. It was a good test. 

"We played good. Regardless of the opponent, we played solid the whole game."

Boston Bruins head coach Jim Montgomery heaped praise on Patrice Bergeron but says he will undergo X-rays after copping a puck to the face in Wednesday's 4-1 win over the New York Islanders.

Bergeron headed down the tunnel early in the third period after a deflected slap shot from David Pastrnak missed his visor and hit him in the face.

The Bruins captain was in apparent pain, having medical attention, but would emerge back on the bench later in the period, helping his side round out a third straight win.

Despite returning to the ice, Montgomery revealed Bergeron had not been cleared by medical staff yet.

"How much respect I have for him coming back after, I know the puck got deflected, but it hits him up high and in the face," Montgomery told NESN.

"The admiration I have and everybody has for him coming back to try to help the team win after that is immense.

"We're hoping that all the X-rays come back good."

The Islanders had taken a first-period lead from Zach Parise but Bruins defensemen Charlie McAvoy and Derek Forbort responded with goals 4:12 apart in the second period to claim the advantage.

Brad Marchand and Trent Frederic added third-period goals for Boston with Charlie Coyle having two assists, while goal-tender Linus Ullmark made 25 saves in his 100th career win.

"I couldn't be more happy, it's been overwhelming," Ullmark said. "I have a lot of gratitude playing with the boys who work so hard every night."

The Bruins are the NHL's only 30-win team, improving their record to 35-5-4.

Jake DeBrusk did not want to see the Winter Classic end as he enjoyed a dream outing at Fenway Park, guiding the Boston Bruins past the Pittsburgh Penguins.

The Bruins replicated their 2010 feat – when they beat the Philadelphia Flyers 2-1 in the previous Winter Classic to be held at Fenway – by downing the Penguins by the same score on Monday.

DeBrusk was the hero with two third-period goals after Kasperi Kapanen gave the Penguins the lead in front of 39,243 fans in the NHL's annual outdoors game.

Speaking to TNT after the game – which the NHL-best Bruins have now won a record three times in four appearances – DeBrusk expressed his gratitude for the chance to play at Fenway.

"I've been lucky enough to play in three of these now, and just look around. I mean, this is Fenway Park all pretty much in yellow," DeBrusk said.

"It's one of those things where you almost don't want it to end."

DeBrusk expected team-mate Taylor Hall to make the decisive contribution after he tied things up by beating replacement goaltender Casey DeSmith just six seconds after a Pittsburgh penalty expired.

While DeBrusk ultimately proved the game-winner by knocking in a rebound with two minutes and 24 seconds left, the goal owed much to Hall's fine work.

"I actually thought it was going to be him [who scored]," DeBrusk said. "I was talking to him on the bench, saying, 'Hey Hallsy, it wouldn't be bad to score your first one at Fenway'."

The defeat leaves the Penguins in fifth in the Metropolitan Division with a 19-12-6 record for the season.

Head coach Mike Sullivan lamented fine margins, including an early injury to goaltender Tristan Jarry.

"There's a fine line between winning and losing", Sullivan said. "It comes down to subtle details. There were momentum swings on both sides in all periods.

"I don't have any update on Tristan. Obviously he is being evaluated for a lower body injury. It's tough to lose a guy that early in the game."

Colorado Avalanche coach Jared Bednar refused to use injury as an excuse after his side were routed 4-0 by the NHL-leading Boston Bruins on Wednesday.

The short-handed Avs slumped to their third straight loss amid a swathe of injuries that have hit the squad, forcing them to call up Cal Burke, Ben Meyers, Sampo Ranta and Andreas Englund from the Colorado Eagles of the AHL.

Colorado, who won last season's Stanley Cup, have used a league-high 34 players this season.

"Listen, if you're quitting, you shouldn't be in the league," Bednar told reporters. "It's a privilege to play in this league.

"It's not always going to be easy. It's a hard game. That's one. Moral victories? We’re going to take it, and we’re going to teach it.

"If this group stays the exact same moving forward for the next one game, two games, five games, I expect us to be better the next game.

"They're going to learn as a group, what it takes to be able to play in this league, what it takes to be able to have success in this league."

For the Bruins, the win improved their overall record to 21-3-1, with Taylor Hall scoring twice along with David Pastrnak and Trent Frederic adding goals. Goaltender Linus Ullmark stopped 23 shots.

Boston's 14-game NHL-record home win streak had come to an end on Monday with a 4-3 loss to the Vegas Golden Knights, with coach Jim Montgomery delighted with Wednesday's response at altitude in Denver.

"Just the response we had after losing the game and ending our [winning] streak at home, we come back and get on the road, and it was a great start to our road trip," Montgomery said.

"We made some big blocks. I thought Brandon Carlo was outstanding on the penalty kill and made some really smart offensive zone plays, too."

Just over a week after he was fired by the Boston Bruins, Bruce Cassidy has been hired as the next coach of the Vegas Golden Knights.

Cassidy guided the Bruins to the playoffs in each of his seasons and compiled a 245-108-46 record during his tenure in Boston. He led the team to the Stanley Cup Finals in 2018-19 before losing to the St. Louis Blues in seven games.

In the following season, Cassidy won the Jack Adams Award as the top coach in the league after the Bruins finished with the NHL’s best record (44-14-12).

Despite that success and coming off a 51-26-5 record this past season, Cassidy was fired on June 6, a month after the Bruins lost a seven-game first-round series against the Carolina Hurricanes.

"The Golden Knights are very pleased to have Bruce come in to coach our team," Golden Knights General Manager Kelly McCrimmon said.

"His success in Boston over six years is extremely impressive. His teams have had a clear identity, having been among the very best in the NHL in terms of goals for, goals against, goal differential and special teams. This is the right coach for our team at this time."

Cassidy fills the opening left when Vegas fired Peter DeBoer on May 16 after the team missed the playoffs for the first time in the franchise’s five-year history.

"I am excited to join an organisation that shares my commitment to winning and can’t wait to work with the talent that has been assembled in Vegas," Cassidy said.

"It’s been impressive to watch the city embrace the Golden Knights from afar, and my family and I look forward to becoming a part of that."

Cassidy is 292-155-53 as a head coach in the NHL, also serving as the Washington Capitals coach for two seasons (2002-2004).

The Boston Bruins have taken the "extremely difficult decision" to fire coach Bruce Cassidy despite reaching the playoffs in each of his six seasons.

Cassidy was appointed as coach in February 2017 – initially on an interim basis – having served as assistant since the start of the 2016-17 season. He had previously led the AHL Providence Bruins.

The Bruins made the former Washington Capitals coach their permanent hire in April of that year, and Boston made the playoffs.

The team had been missing from the postseason in the previous two seasons but would go on to be regulars with Cassidy behind the bench.

He took the Bruins all the way to Game 7 of the Stanley Cup Finals in 2019, only to lose to the St. Louis Blues.

Despite the Bruins continuing to make the playoffs, that was as close as Cassidy would come to adding a seventh championship, this year losing in the first round to the Carolina Hurricanes.

Cassidy leaves Boston having overseen 399 regular season games, the fifth-most in team history. With a record of 245-108-46, he is tied third for most Bruins wins.

General manager Don Sweeney explained his dismissal, saying in a statement: "Today I informed Bruce Cassidy that I was making a change.

"After 14 years working with Bruce, this was an extremely difficult decision.

"I want to thank and acknowledge Bruce for all his work and success with the Bruins organisation. His record for the Bruins is impressive, and we are appreciative of Bruce both professionally and personally.

"After taking some time to fully digest everything, I felt that the direction of our team for both this season and beyond would benefit from a new voice."

Nick Paul scored twice, including a stunning individual goal late in the second period, as the Tampa Bay Lightning defeated the Toronto Maple Leafs 2-1 in Game 7 on Saturday.

The two-time defending Stanley Cup champions came from a goal down in the previous two games, and had to do it again on the road at the Scotiabank Arena after Thursday's overtime win to level the series.

Morgan Reilly scored for Toronto but Andrei Vasilevskiy stopped an eventual 29 shots to keep the Lightning in the game, before Paul's brace secured the series win.

The Leafs were condemned to their seventh consecutive playoff series loss, and have not made the second round since 2004. After the match, Leafs head coach Sheldon Keefe commended the reigning champions on their series win.

"They [Tampa Bay] don’t get a lot of credit because you don’t really think of them this way, but we knew coming into this series that going into third periods down against this team was going to be a challenge," he said post-game.

"They are the number-one team in the NHL when it comes to limiting chances against when up a goal in the third period. All regular season, they were that.

"That is sort of the hallmark of their success. That is championship hockey. They didn’t give us a great deal in that third period tonight. Those are the things I take away - just how hard they defend and how they prioritise defending."

In Saturday's other results, the Carolina Hurricanes won their series-deciding game at home to the Boston Bruins 3-2, while the Edmonton Oilers claimed Game 7 against the Los Angeles Kings with a 2-0 win.

Brayden Point scored the winning goal in overtime and forced a Game 7, as the Tampa Bay Lightning secured a thrilling 4-3 victory over the Toronto Maple Leafs on Thursday.

Ondrej Palat, Anthony Cirelli and Nikita Kucherov also scored for the reigning Stanley Cup champions, but they had to battle until 1:56 remaining in overtime for Point's sealer.

The Lightning had to fight their way back from 3-2 down in the final period with their season on the line, after Leafs captain John Tavares scored twice in the second period's closing 34 seconds.

With his side dropping a lead for the second straight game, Tavares said the focus is now on regrouping as the series heads back to Toronto for the decider.

"We worked hard all year to earn home ice and we've got a great opportunity going home in front of our fans to try to close this thing out," he said.

"So just regroup here, and look forward to the opportunity. This is what the game's all about."

The Boston Bruins also forced a Game 7 after they defeated the Carolina Hurricanes 5-2, while the St. Louis Blues advanced to the second round, beating the Minnesota Wild 5-1 in Game 6.

In Thursday's final game, the Edmonton Oilers evened their series up with the Los Angeles Kings in Game 6, winning 4-2.

Auston Matthews says his game-winner was "pretty special" after the Toronto Maple Leafs battled back from two goals down to win 4-3 over the Tampa Bay Lightning in the NHL playoffs on Tuesday.

The Maple Leafs trailed 2-0 after the first period but rallied with Matthews settling the contest with their third goal in the third period.

The win means Toronto lead 3-2 in the best-of-seven series against the reigning Stanley Cup champions.

"It was pretty special," Matthews told reporters, speaking about the goal. "To battle back from down two goals, and never losing hope and competing, that was big."

Matthews led the NHL across the regular season with 60 goals but he had not scored in the playoffs since Game 1 of the series.

Teammate John Tavares, who pulled one back during the second-period power play, praised the NHL's back-to-back Rocket Richard Trophy winner Matthews, who was also credited with seven hits.

"His whole game is all just really good," Tavares said. "When you score 60 goals, that's going to get [discussed], and how he scores it in different ways and the uniqueness of his shot in his abilities, but his all-around game is as good as anybody's in the league.

"He's going to play hard and compete because they're making it hard on him to earn his ice and opportunities, so good for him to play them hard."

The victory means Toronto are one win away from the franchise's first playoff series victory since 2004.

"I just think we needed to possess the puck a little bit more," Matthews said. "Get on top of them and be forechecking and not giving them as much time and space. We were on top of them and had our heads up to make plays."

Elsewhere, Adrian Kempe's over-time goal earned the Los Angeles Kings a 5-4 win over the Edmonton Oilers, having blown a 3-1 lead.

The goal was Kempe's second of the game, as he finished with a three-point performance. The result puts the Kings up 3-2 in the series.

The Carolina Hurricanes also moved up 3-2 in their series against the Boston Bruins with an emphatic 5-1 win after losing their past two.

Rookie Seth Jarvis scored twice and Antti Raanta finished with 34 saves.

The St Louis Blues piled on three third-period goals, all from a Vladimir Tarasenko hat-trick, to secure a 5-2 win over the Minnesota Wild to lead their series 3-2.
