Ovechkin scored at 1:26 of the first with a shot from the high slot to give the Capitals a 1-0 lead. The puck came off the stick of Penguins forward Patric Hornqvist on a rush up ice.
"They came out flying," Murray said. "We didn't have an answer for it."
Vrana finished a pass from Lars Eller with five seconds left on a power play to make it 2-0 at 14:54 of the first for his first playoff goal. The Penguins used a coach's challenge for goalie interference on the play, but the call on the ice stood.

Connolly scored after a stretch pass from Eller at 2:08 of the second for a 3-0 lead.
"We need to have a better start," Penguins coach Mike Sullivan said. "We need more pushback from the drop of the puck. Listen, we knew they were going to come out hard. We're up 1-0 (in the series) after the first game, we knew they were going to come out hard. We didn't match the urgency."
Holtby helped preserve the lead for Washington in the second period when it was outshot 16-6. He stopped Hornqvist, knocking the puck out of the crease with his stick at 10:56 and then stopped Guentzel's rebound chance with a pad save at the left post.
"I thought Braden was real solid all game," Capitals coach Barry Trotz said. "I thought he made some timely saves. He moved well. They were trying to make everything very difficult and he responded the way he always has."
Letang's point shot at 13:04 of the second made it 3-1.
The Penguins appeared to make it 3-2 at 9:03 of the third period when Hornqvist tucked a puck underneath Holtby. However, it was not ruled a goal on the ice and the call stood after a review.

Backstrom scored an empty-net goal at 19:53 of the third to make it 4-1.
Washington trailed 2-0 losing each game at home in its past two playoff series.
"We have a confident group, so we don't get that down," Holtby said. "We believe we can win any game no matter the circumstances. We focus on the task at hand and tonight that was Game 2. Game 1 was a long time ago."

They said it
"We have to do a better job of being more difficult to play against and limiting some of the chances they get. But having said that, we had a number of quality chances as well. At some point, we have to find a way to score goals. That's something we'll get to work on." -- Penguins coach Mike Sullivan
"We know that they've got guys that can hurt you. Game 1 it was tough, we played a really good game and they just kind of found a way to get some breaks and score some timely goals. I think we learned from that this time around, I think we weren't as loose, I think we were a little more solid as the game went on." -- Capitals forward Brett Connolly on holding onto a two-goal lead
