The Bruins, offline and off-kilter for most of Sunday evening, are on their first three-game losing streak of the year.

Danton Heinen and Brad Marchand scored in the third period, bringing the Bruins back from two goals down. But despite a penalty shot and a power play in the final five minutes, they couldn’t produce the winner. They even survived a too-many-men call with 21 seconds left in overtime.

The Flyers’ Joel Farabee scored in the shootout, giving Philadelphia a 3-2 win. Farabee, the ex-BU Terrier, pitched a forehand over Jaroslav Halak in the first round to lift the Flyers. Charlie Coyle, Marchand, and David Pastrnak couldn’t beat Carter Hart at the other end.


With 7:38 left in regulation, Marchand ripped a wicked, one-footed snapper far side on Hart to tie the score at 2, following up Heinen’s tally 5:59 into the third. The Garden went from lifeless and sullen to loud and lovin’ it.

Heinen scored on the 14th shot of the game for Boston on a turnaround shot in front. Heinen got the opportunity to beat Hart thanks to Coyle’s possession work in the zone. It was Heinen’s fourth goal in 17 games.

That woke up the Bruins, who sent out their top line after the goal. Marchand had a golden one-timer chance off a cross-ice feed from Pastrnak, but snapped it high over the net. Marchand made up for it with his 11th goal of the year at 12:22, tying him for sixth with Detroit’s Anthony Mantha in scoring.

With 4:56 left, Pastrnak, hooked by Ivan Provorov on a breakway, had the go-ahead goal on his stick on a penalty shot. He drifted from left to right, slowed in the slot, put on two upper-body fakes and tried to outwait the netminder . . . but couldn’t lift it over a prone Hart.


Marchand drew a tripping call on Oskar Lindblom with 3:20 left, but Hart made a save on a Pastrnak one-timer from the circle, and Bergeron flipped a cross-ice one-timer wide of the net.

The Bruins had a season-low 10 shots through two periods.

“Poor,” Cassidy said with distaste of the Bruins’ start. “That’s about it, to sum it up. Poor.”

He attributed it to Philadelphia playing a strong road game, and his team misfiring on its chances to make game-changing plays.

“We never got an opportunity to put them on their heels, in any way, shape or form,” Cassidy said. “That’s my explanation of the start. We need to correct it in the hurry.”

The Bruins (11-3-3) host the Panthers on Tuesday.

■  Is this the Stanley Cup hangover coming to swallow the Bruins?

“Maybe it’s starting to hit us a little,” Cassidy mused, adding that the absence of “players up front” (read: Karson Kuhlman and Jake DeBrusk) isn’t helping matters. He believes his team can get out of its own end cleaner, manage the puck better through the neutral zone, and shoot more when attacking.

“I don’t know if it’s an energy issue,” he said. “We talked about [it], we thought the residual effect of last year, maybe it’s kicking in earlier than we thought. We’ll talk to the players and see where it leads.”

■  Torey Krug was not available for the overtime period because of an upper body injury, Cassidy said. “I was told Torey’s off the bench, gone,” he said. “We managed without him. We’ll see how he is tomorrow.”


■  His players falling to 0 for 7 in shootout attempts, Cassidy was ready to try other hands than his three shooters from Sunday — Marchand, Pastrnak and Coyle, all now 0 for 2, and DeBrusk (0 for 1).

“We can’t let it get frustrating,” Coyle said.

■  In the shootout, Coyle couldn’t beat Hart with a cutback and forehand stuff-in along the ice.

■  Joakim Nordstrom’s full-out shot block in the final seconds kept the shots tied, 27-27, after 60 minutes. Nordstrom had missed the previous six games with an elbow infection.

The Bruins heard some rare boos at TD Garden after the first period, when they allowed a pair of goals. They hadn’t faced a 2-0 deficit after 20 minutes since Oct. 8, the third game of the season, in Vegas.

■  Hoping to end a two-game losing streak, they came home and were outshot, 14-5, in the first 20, and 20-10 through two periods. They produced one shot in the first 13 minutes of the second period, and six in the first 33 minutes of the game.

■  Through two periods, the top line of Marchand-Bergeron-Pastrnak combined for four shots, two each from the wingers and none from pivot Bergeron.

■  The Flyers, who beat Toronto in a shootout the night before, raced out to a 12-3 shots edge. They scored the opening goal by going on a 4-on-1 against Matt Grzelcyk. Halak made the first stop, but Travis Konecny cleaned up the rebound at 13:50. Sean Kuraly had a chance to clear, but whiffed.


■  The Bruins entered the evening 2-1-1 when opponents scored first, and 9-2-1 when they did the same.

■ Marchand drew a high-sticking call 24 seconds after the opening goal, but the Bruins got nothing of note from the first unit. They had no shots other than a heavy Charlie McAvoy one-timer from the circle, which Hart shunted aside.

■ The Flyers pushed the shots edge to 14-4 and the score to 2-0 on a bullet of a shot by defenseman Phillipe Myers, who beat Halak far side from the right dot. After a dish from Konecny, the 22-year-old backliner had ample time to load up, Connor Clifton and Kuraly late to close on him.

■  The Bruins appeared to score in a net-front pileup 2:50 into the second period, when Par Lindholm pushed the puck in amid a net-front scramble. Officials consulted each other for three minutes, but saw no reason to change the “no goal” call on the ice, and the scoreboard to 2-1, Philadelphia. The NHL’s Situation Room in Toronto initiated the review, noting that referee Francis Charron informed them the puck crossed the line because of goaltender interference, ostensibly Lindholm pushing both pad and puck across the red. Charron explained the deal to both benches, but said nothing to the crowd.

■  Cassidy said his video review staffers and goalie coach Bob Essensa, who works on the ninth floor, told him a challenge would have likely been unsuccessful because a Bruin stick pushed puck and pad over the line.


■  Pastrnak’s second-period hooking penalty registered as his third offensive-zone infraction in the last two games. The Bruins killed the minor.

■  The move to place third-line center Coyle up on Krejci’s right wing did not pay immediate dividends. Coyle did not land a shot, missing both attempts, in the first two periods. Linemate Heinen saw his one attempt blocked. Krejci did not attempt a shot.

■  Halak, making his first start since a Nov. 4 win over Pittsburgh, stopped 18 of 20 through two periods. His best work came late in the second, when he stopped tough bids from Claude Giroux and Travis Sanheim to keep it a two-goal game.

■  At a stoppage midway through the first period, Zdeno Chara was recognized and given a standing ovation for playing his 1,500th game. The Bruins played a tribute video, a fuller version of which was previously released online, that included fellow captains Alex Ovechkin, Jonathan Toews, Ryan Getzlaf, Anze Kopitar, and Nick Lidstrom congratulating him. Both teams rapped their sticks.
