"We had trouble getting energy and anything really going," Panthers interim head coach Andrew Brunette said. "[The Bruins] played hard, a little more desperate than we did, hence the score."
With Sam Reinhart providing a screen in front, Gustav Forsling opened the scoring when he ripped a shot past Linus Ullmark to put the Panthers up 1-0 eight minutes into the first period.
Taking advantage of a defensive miscue, Erik Haula beat Sergei Bobrovsky on a 2-on-1 rush to get the Bruins on the board and make it 1-1 at 16:18. Just six seconds later, Taylor Hall doubled the lead for Boston when he buried a shot from the slot on a breakaway to make it 2-1 at 16:24.
Just beating the buzzer to wipe the slate clean heading into the first intermission, Sam Reinhart jumped on a rebound and fired the puck past Ullmark and into the cage on the power play to get the score knotted back up at 2-2 with less than a second remaining on the clock in the period.
"It's small details," Forsling said. It could've gone either way. I think we had a good push, but didn't come up with a goal. I think after the first we weren't that happy, and then we came out [better] in the second. It's a tight game."
Regaining the lead for the Bruins early in the second period, Jake DeBrusk followed up on a shot from Brad Marchand and powered the rebound past Bobrovsky to make it 3-2 at 4:59.
Late in the third period, Marchand put the Bruins up 4-2 with just 3:05 left in regulation when he fired the puck into an empty net after the Panthers had pulled Bobrovsky for the extra attacker.
Finishing with 34 saves, Bobrovsky stopped 23 of 24 shots over the second and third periods.
"Good game, good flow, saw lots of pucks," said Bobrovsky, who remains one win shy of becoming the first 40-win goalie in franchise history. "Unfortunately we didn't win tonight, but it was a good game. The atmosphere was kind of a playoff atmosphere. It was fun to be there."
With just two games left until the playoffs, the fun is only just beginning.
