PITTSBURGH - The Washington Capitals are well aware of their franchise's inglorious past, one filled with unmet expectations and gut-wrenching collapses.

And they don't care. It's not 1992. It's not 1996, 2009 or 2016, for that matter.

The Capitals spent the better part of the NHL season insisting that this time, things would be different. No longer were they burdened by the weight of the team's history of playoff flameouts, one most of the guys in red, white and blue had nothing to do with.

Backed up to the precipice against a rival that's tormented them for decades, the Capitals finally punched back on Monday night.

And they punched back hard.

Andre Burakovsky scored twice and Nicklas Backstrom sniped his sixth goal of the playoffs as Washington beat the Pittsburgh Penguins 5-2 to force a Game 7 in their seesaw Eastern Conference semifinal.

This is the fourth time the two teams will meet in a winner-take-all. The Penguins have won each of the previous three.

"I haven't been here forever but, one, I've never been in a Game 7," said Washington forward T.J. Oshie, who opened the scoring with a first-period powerplay goal.

"Two, I've never been past the second round. I know how much it would mean to me and I imagine it would be the same to every guy in this locker room."

The Capitals are as close as they've ever been to their first appearance in the conference final in 19 years after rallying from a 3-1 series deficit to win Game 5 at home and then delivering a masterful performance 48 hours later in a city that's often been their burial ground..

A year ago, Washington trailed Pittsburgh 3-1 in the second round, won Game 5 at home only to fall in overtime of Game 6. Intent on not repeating history yet again, the Capitals jumped on the defending Stanley Cup champions early and didn't relent until the things were well in hand and a once raucous arena was largely empty.

"Since Game 3 we've had a sense of calmness about what we're doing," Washington coach Barry Trotz said. "We're having fun now. The fun part has been the obstacle."

Jake Guentzel picked up his playoff-leading ninth goal and Evgeni Malkin added another 52 seconds later late in the third period to make the score look cosmetically better, but the Penguins were never in it.

Marc-Andre Fleury finished with 21 saves and received little help in front him.

"I think we were probably guilty of making a few mistakes early on and then probably chasing our mistakes after that," said Pittsburgh captain Sidney Crosby, who had an assist in 20 minutes but was largely a nonfactor in his second game back after missing Game 4 with a concussion.

Pittsburgh coach Mike Sullivan tinkered with his line combinations reuniting the HBK line (Carl Hagelin, Nick Bonino and Phil Kessel) that played an instrumental part in the team's Cup run last spring.

Sullivan also moved rookie Guentzel alongside Malkin and put Conor Sheary with Crosby.

None of it worked, as Washington pushed the Penguins around.

Crosby took a nasty spill in the first period when he was slammed into the end boards head-first while he tangled with Carlson. He remained in the game but found little room to work.

Then again, neither did any of his teammates as Washington dominated.

Pittsburgh's first shot in the opening 17 minutes was a 136-foot flip by Brian Dumoulin that made its way to Braden Holtby for the first of his 16 saves. By then the Capitals already had a 1-0 lead on Oshie's fourth of the playoffs.
