The Philadelphia Flyers pulled off their first postseason upset since 2012 when they knocked the Pittsburgh Penguins out of the Stanley Cup playoffs on Wednesday.

The Flyers begin their quest for another upset when they visit the Carolina Hurricanes on Saturday in Raleigh, N.C., to kick off their Eastern Conference semifinal showdown. Philadelphia, which used six games to take out its in-state rival, finished 15 points back of the Hurricanes in the regular season.

Despite the odds against them, the Flyers begin the series with confidence. That starts with their last line of defense, goaltender Dan Vladar, who was a huge key to the first-round victory.

'I think I can speak for the whole locker room. There was never a doubt,' said Vladar, who posted a 1.61 goals-against average with a .937 save percentage and two shutouts in six games against Pittsburgh. 'If somebody had a doubt, it's their problem. That's not us.'

Certainly, beating the Hurricanes would be a huge feat for the Flyers. Carolina finished atop the Eastern Conference and second overall in the league. Plus, Carolina won three of four meetings during the regular season and has claimed 16 of their last 18 encounters with the Flyers.

However, all four clashes between the clubs this season went to overtime.

'They're a really good team, play with a lot of pace,' Philadelphia defenseman Travis Sanheim said. 'We had really good games with them all year. ... Really excited about the challenge.'

As good as the Flyers have been at defending, especially after the Olympic break, their abilities will be put to the test. Carolina has a lethal attack that was on full display during a first-round sweep of the Ottawa Senators.

'We've got to possess the puck more. That's the next level,' Philadelphia coach Rick Tocchet said. 'We have to be better at controlling the puck, but that's controlling the ice.'

Carolina, the only team from last year's final four to reach the second round of this year's playoffs, was surgical in dismissing the Senators.

The Hurricanes never trailed in any of the games, propelled by goaltender Frederik Andersen's shutout in the opener. While Andersen was stellar between the pipes while posting a 1.10 goals-against average and .955 save percentage, the Hurricanes showed off their ability to stifle opponents.

'The way we played, I thought, was really consistent, from start to finish of every game,' said Canes coach Rod Brind'Amour. 'It was just the same, and everybody was dialed in. You're not always going to win those games, but it gives you a chance to win every night.'

If there is one cause for concern for the Hurricanes -- beyond the fact that 31-goal, 70-point forward Andrei Svechnikov was held without a point in the first round -- it is their time off since finishing the Ottawa series on April 25. Carolina has gone one week between games.

'It's a gift and a curse,' defenseman Shayne Gostisbehere, a former Flyer, told reporters. 'If we play (well), people will be like, 'It's the rest.' If we play bad, they'll be like, 'It was the rest.''

To this point, the break has been a gift because it provided much-needed recovery time. Defenseman Alexander Nikishin and forward Nikolaj Ehlers practiced fully on Friday. Nikishin suffered a concussion in the clinching game, while Ehlers is poised to be back in the lineup after missing Game 4 against Ottawa due to a lower-body injury.

'We hope everyone will be ready to go, and it certainly looks like that,' Brind'Amour said.
