Jarry made a pad save against Alex Ovechkin on a breakaway with 4:07 left in the period.
Ovechkin finished with four shots on goal in 18:42 of ice time.
“I think we played well in the first period,” said Ovechkin, who is Washington’s captain. “Second one, we didn’t score. They scored, and that’s kind of the game.”
Smith, acquired in a trade with the Vegas Golden Knights on June 28, scored his first goal with the Penguins with a shot from the left circle off a pass from Malkin at 16:57 of the third period for the 4-0 final.
“I thought Geno was on his game tonight,” Sullivan said. “When he’s on his game, it seems like the puck follows him around. … That play he made on Reilly’s goal at the end, just an unbelievable pass. It started with a track, just tracking the puck from behind.
“He was playing at both ends of the rink. He’s competing hard. I just think when he’s on his game, he’s as dominant player as there is in the League.”
