Bradley scored his first two playoff goals, Ovechkin added a highlight-reel tally, rookie Simeon Varlamov posted his second shutout of the opening round, and the Capitals beat the New York Rangers 4-0 in Game 5 on Friday night to avoid elimination.
"We never give up. We fight. We love the situation," Ovechkin said. "It's hard, but we love it."
The seventh-seeded Rangers, who played without Sean Avery, lead the best-of-seven series 3-2 heading to Game 6 in New York on Sunday.
"Something has to give with our top guys. I'm not trying to insult them. We have some great guys in that room," said Rangers coach John Tortorella, who threw a plastic drinking bottle into the stands during a third-period confrontation with a fan. "This is a game where your best players have to be your best players, and it won't happen until our best players are our best players - not kids."
The Capitals are in a familiar position: They also faced a 3-1 deficit against the Philadelphia Flyers in the first round last season before rallying to win Games 5 and 6 - only to lose Game 7 at home in overtime.
Knowing they need to win three consecutive games, Washington picked up some momentum Friday from an unlikely source. Bradley is a 30-year-old right wing who never recorded a goal in 21 previous career post-season games.
Indeed, Bradley ranked 17th on the Capitals in points during the regular season - behind Ovechkin and Semin and Mike Green, of course, but also trailing some stay-at-home defencemen - with a total of five goals, only one over the final 42 games.
Yet Bradley put the puck in the net twice in a span of less than 7 1/2 minutes Friday. The first goal was shorthanded and came on the game's first shot, before five minutes had elapsed. Several Capitals skated over to pile on Bradley, knocking him to the ice.
Then, 12:07 in, Bradley squeezed the puck past Lundqvist from a seemingly impossible angle beside the net.
"Every great goalie, every now and again, makes a mistake," Capitals coach Bruce Boudreau said.
"I'm not going to lie: I wasn't try to score like that," he said. "I was just trying to get it on net."
Suddenly, it was Bradley 2, Rangers 0, and he was receiving celebratory head-butts on the helmet from Ovechkin.
"Brads is the superstar tonight," Green said. "He's a guy who works hard, plays few minutes, and for him to step up like that tonight - he carried the team in the first period."
Lundqvist, so good earlier in the series, particularly Games 2 and 4, was serenaded by loud taunts of "Hen-rik! Hen-rik!" from the red-clad crowd. Those taunts returned 4:57 into the second period, when Semin's fourth goal of the series made it 3-0.
Ovechkin led the league in goals each of the past two seasons and is the reigning MVP, but Lundqvist held him without a goal until Game 4. Now Ovechkin has scored in consecutive games, and the latest ranks with his masterpieces - look for it on YouTube.
The Russian left wing brought the puck across the blue-line and, moving to his right, swept past Rangers captain Chris Drury. Then, swerving to his left, Ovechkin curled around Derek Morris while passing the puck to himself through the defenceman's legs.
Approaching the net, Ovechkin now found Aaron Voros hanging on his back. As both fell to the ice - Ovechkin face-first, Voros hanging on like a football tackler - Ovechkin lifted a backhander past Lundqvist with 29 seconds left in the second period.
That's when the "M-V-P!" chants began, and they didn't subside until Ovechkin left for the locker room.
