WASHINGTON -- Nicklas Backstrom scored two goals in the third period for the Washington Capitals in their sixth consecutive win, 5-2 against the Vegas Golden Knights at Capital One Arena on Saturday.
Evgeny Kuznetsov had a goal and an assist, Jonas Siegenthaler scored his first NHL goal, and Jakub Vrana and John Carlson each had two assists for Washington (13-2-3), which is 10-0-1 in its past 11 games, outscoring opponents 50-31. Braden Holtby made 30 saves in the win.
"I think we're working together as a team," Backstrom said. "We're doing all the details right. We're trying to follow the system that the coaches want us to play. I feel like when you have confidence like we have … we're just trying to keep going and get better every day. So far, so good."

Max Pacioretty and Reilly Smith scored for Vegas (9-6-3), which is 1-1-1 on its four-game road trip and 1-1-3 in its past five. Marc-Andre Fleury made 29 saves.
"I don't think we played as good as we had in the past lately, and we just didn't look [like we were] getting ready to beat a good team," Golden Knights coach Gerard Gallant said. "We had to play a lot better than that."

Backstrom scored on the power play with a shot from the right face-off circle that trickled through Fleury's pads to make it 4-2 at 11:30. He scored an empty-net goal with 46 seconds remaining for the 5-2 final.
Kuznetsov scored on a breakaway off a Dmitry Orlov stretch pass to give the Capitals a 1-0 lead 58 seconds into the game.
"When we support each other in our zone when we have the puck, that's how we get those 3-on-2, 2-on-1 looks," Kuznetsov said. "The hockey's pretty simple right now. You have to go back for the puck. Not only one defenseman. It has to be all five guys."
Tom Wilson made it 2-0 with a shot from the high slot at 5:53 off a pass from Vrana following a turnover by Vegas forward Jonathan Marchessault.
"Obviously, it's a tough way to start the game, but I feel like I wasn't good," Fleury said. "I didn't make the key saves, or I didn't change the game in a good way for us. I didn't make those key saves to keep the score close."

Pacioretty cut it to 2-1 when he scored unassisted at 8:57, knocking a loose puck past Holtby from the slot following a face-off.
Siegenthaler took a cross-ice pass from Travis Boyd and beat Fleury far side from the left circle to make it 3-1 at 15:32 of the second period. His first goal came on the one-year anniversary of his NHL debut.
"It feels pretty good, even better with a win," he said. "It's been exactly a year. It took a year. It feels great."
Smith pulled the Golden Knights within 3-2 with a one-timer from the top of the left circle on the power play at 17:27.

The Golden Knights had two power plays while trailing 3-2 in the third period.
"That definitely hurt," Gallant said. "We scored one late in the second that made it 3-2, and we had the one starting the third that we didn't get much on, and the next one, we didn't get much on. That was a huge part of it."
They said it
"Consistency is a hard thing in hockey to find. I think we're not playing with the swag we should have, the confidence that we should have. There's a glimpse of it, and I think it's [important] to stay a little bit more simple. It doesn't matter where we play, just play a strong forecheck game, and when we do that, I think we're one of the best teams." -- Golden Knights forward Jonathan Marchessault
"I was really impressed with our start to the game because they were ready to go. They've been hyping this game up, and we responded. I challenged our guys pretty good before the game and got, I thought, a really good response to start with." -- Capitals coach Todd Reirden
