Ovechkin made it 2-0 at 18:35. Matt Roy drove to the net and, after drawing Vladar to the left post, centered the puck before it bounced around the slot, where Ovechkin tipped it home.
Sanheim pulled the Flyers within 2-1 when he scored with a snap shot from the high slot 39 seconds into the second period. The goal was initially waved off due to goaltender interference by Dvorak, but the Flyers challenged the call, and it was overturned after a video review.
“They came out the first 10, 12 (minutes) and tried to bully us, and I thought after that we started to get our game,” Flyers coach Rick Tocchet said.
Carl Grundstrom tied the score 2-2 at 4:36, scoring in front after a backhand pass from Trevor Zegras in the corner.
Chychrun gave the Capitals a 3-2 lead with a power-play goal at 6:58, scoring on a one-timer from the left dot off a backhand pass across the point from Leonard.
“Well, I think we moved the puck quickly tonight (on the power play)," Wilson said. “I think we were just keeping it simple, getting pucks to the net and moving the puck.”
Leonard made it 4-2 at 17:37. He received a pass in the right circle from Dubois and beat Vladar with a glove-side snap shot on the power play.
“I thought our 5-on-5 play was good,” Tocchet said. “They won the special teams. That was the difference in the game.”
Dvorak pulled the Flyers within 4-3 at 33 seconds of the third period when he scored from the left post off a pass by Konecny from behind the net.
Ovechkin made it 5-3 at 3:47, receiving a backhand pass from Connor McMichael and putting a diving snap shot past Vladar from the bottom of the right circle.
“Just dragging guys into the fight, playing his best hockey at the most important time of the year, and scored a couple of huge goals getting to the net, and we needed those,” Carbery said of Ovechkin.
