Sergei Bobrovsky looked as poised facing 58 shots as he did before the game when he calmly walked down the hallway in a buttoned-up beige trenchcoat.

On the ice, Bobrovsky stood out even more. The goaltender with a history of playoff struggles looked like his two-time Vezina Trophy-winning self in making 54 saves as the Columbus Blue Jackets beat the Washington Capitals 5-4 on Sunday night on Matt Calvert's overtime winner to take a 2-0 lead in the first-round playoff series.

"He's our best player and he was our best player by a mile tonight," said Calvert, whose scored on a one-handed rebound shot 12 minutes, 22 seconds into overtime.

Through two games this year, the second of which coach John Tortorella called "one of the best goaltending performances" he has seen, the reserved Russian has stopped 81 of 88 shots to send Columbus home for Game 3 Tuesday in a place it's never been before.

The Blue Jackets had never led a playoff series until Thursday night.

"Your career is a journey and you learn some things here and there," Bobrovsky said. "It doesn't matter what's in the past. When we're gonna play third game, it doesn't matter what happen tonight. Each moment is huge right now."

Alex Ovechkin scored twice on the power play and T.J. Oshie tied it with 3:35 left to give Washington a chance.

Penalty trouble almost cost the Blue Jackets as much as the Capitals, but they were left celebrating after Calvert's goal held up to an offside review.

"Luckily, I got the rebound, had one hand on my stick and the rest is history," Calvert said. "Two games in overtime, that can really crush a team."

The Capitals are the sixth team to lose Games 1 and 2 of a best-of-seven series in overtime, and the previous five have all lost.

Pittsburgh 5, Philadelphia 1: Sidney Crosby matched a postseason best with four points on a goal and three assists, helping the Penguins silence the raucous crowd and beat the host Flyers for a 2-1 lead in the Eastern Conference first-round series.

Crosby, who has 93 points in 63 career regular-season games against Philly, shut up the orange-and-black die-hards who hurled derogatory chants at him with a wraparound goal off a turnover midway through the first.

The Flyers haven't won a playoff series since 2012 and pulled out all the theatrical stops. Flyers fans even stuck photos of longtime nemesis Crosby inside urinals throughout the arena.

Two of the so-called fiercest rivals in the NHL have provided three lopsided games: Pittsburgh's 7-0 win in Game 1 and Philadelphia's 5-1 victory in Game 2 could about qualify as nail-biters in this series.

Crosby scored his fourth goal of the series in the first period, and Derick Brassard, Evgeni Malkin and Brian Dumoulin scored in the second. Malkin and Dumoulin scored 5 seconds apart.

Western Conference

Vegas 3, Los Angeles 2: James Neal scored the go-ahead goal with 5:37 left and William Karlsson added the decisive tally 21 second later for the Golden Knights, who went up 3-0 on the Kings.
