Ullmark made 26 saves.
With 4:30 remaining in the first period, the Pens changed their goalies as an injured Jarry left for the locker room. Sullivan said that Jarry was being looked at for a lower body injury.

The Pens took the lead with 11:20 left in the second period, as Danton Heinen fed linemate Kasperi Kapanen for a point- blank shot that beat Ullmark. The goal came after the Bruins killed four minutes of power-play time after minor penalties to David Pastrnak and Hampus Lindholm.

The game was tied at 12:14 in the third quarter. After a Pittsburgh penalty expired, Brad Marchand found DeBrusk on the side of the net and he beat De Smith with a wraparound.
Taylor Hall made a great stickhandling move to the net that led to DeBrusk's game winning goal. The puck was knocked in on the rebound by DeBrusk.
He is a big goal scorer. He has been with the Bruins for over a decade. The puck sometimes finds him when he plays with that confidence. He was responsible for it happening.
The puck crossed the line after the final buzzer when the Pens were close to tying the game. Ullmark raised his arms in the air as the Bruins surrounded him, while Pittsburgh's players were on the bench waiting for the no- goal to be confirmed.
There was a lot of confusion at the end. It felt like we had it under control. Afterwards, it was pure joy. It has been a dream of mine since I saw the first one in Sweden. I was very jealous of the people who played before in the game. We had the chance.
Kris Letang went back to Montreal to be with his family after his father died.
The game was competitive. It was a close game. There is a fine line between winning and losing.
