Frederic made the final score 2-1 with a power play goal at 5:26 of the second period. It was his first goal in 10 games.

“If the team is doing well, I think it’s good for the individual,” Frederic said. “We played well, we won. Every time that happens, I feel like you feel good as an individual too.”

York gave the Flyers a 3-1 lead at 15:29 with a shot from high position.

“We are a good team and we expect to win every game,” said York. “It obviously hurts to lose this game. But we have an opportunity to come back tomorrow (at home against Utah Hockey Club) and hopefully come out victorious.”

Joel Farabee nearly scored on a breakaway at 2:03 of overtime, but Swayman made the stop to keep Boston alive before Zacha’s winner.

“This is huge. That’s a huge save,” Bruins defenseman Charlie McAvoy said. “That and coupled with a special play right after, you know, that gives us two points. That was great.”

NOTES: Travis Konecny, who leads Philadelphia with 31 points (13 goals, 18 assists) in 27 games, had an assist, but the forward missed the final 13:55 of the third period and did not play in overtime. Tortorella said Konecny ​​was removed from the game by a concussion observer. Konecny ​​was allowed to return, but Tortorella kept him out for what the coach called undisciplined play. … Michkov joins Eric Lindros (three games, 1992-93) and Peter Zezel (twice, 1984-85) as the third Flyers teenager with three consecutive multi-point games. … Marchand’s goal marked the 15th time he scored an equalizer in the final 10 minutes of the third period. In the same scenario, he tied with Ray Bourque (15) for the most goals in Bruins history. … Sanheim’s assist on York’s goal was his 200th NHL point.
