PITTSBURGH -- The Philadelphia Flyers climbed closer to the second wild card into the Stanley Cup Playoffs from the Eastern Conference by defeating the Pittsburgh Penguins 6-2 at PPG Paints Arena on Sunday.
Philadelphia (35-32-8) is six points behind the Boston Bruins. The Flyers and Bruins each have seven games remaining.
"You look at it one game at a time," Flyers defenseman Shayne Gostisbehere said. "We win. It takes care of everything else. We just control what we can control right now. That's winning games."

Pittsburgh (46-18-11) remained tied with the Columbus Blue Jackets, who have one game in hand, for second place in the Metropolitan Division. They're each three points behind the Washington Capitals.
The Penguins lost in regulation at home for the fifth time in 38 games this season (29-5-4). They lost each of their three games in the past four days (0-1-2).

"I'm just trying to go out every night and give it my best shot," Weal said. "My game is to create opportunities offensively and spend as little time [in the defensive zone] as possible. I try to do that every night. Consistency is key."
Filppula gave Philadelphia a 2-1 lead with his ninth goal of the season at 12:49 of the second period. The goal was upheld after Pittsburgh challenged for goaltender interference.
Weise made it 3-1 at 1:11 of the third period and Voracek made it 4-1 at 8:41 before Patric Hornqvist cut it to 4-2 at 13:36.
Radko Gudas extended the lead to 5-2 with an empty-net goal at 17:31, and Gostisbehere made it 6-2 at 18:58.
Murray made 27 saves. He has allowed at least four goals in four of his past seven starts.
"They had the momentum pretty much the entire game," Murray said. "For a lot of the time they were really swarming in our end zone. … Just one of those games that we didn't get the bounces and things didn't go our way."
Penguins forward Conor Sheary left after playing 3:56 in the first period. Forward Tom Kuhnhackl took his place at left wing alongside center Sidney Crosby and Bryan Rust for the remainder of the first before Chris Kunitz took over to start the second period.
Sullivan said Sheary is day-to-day with a lower-body injury.
Goal of the game
Filppula battled Cole near the Penguins crease before Weal spun and shot off the inside of Nick Bonino's right skate. With Murray scrambling in his crease, Filppula shot under him.

Save of the game
Before Cullen made it 1-0, Mason kept Sheary from scoring the opening goal earlier in the first period. Phil Kessel redirected a pass through the Philadelphia crease to Bonino, who tipped it wide of the left post before Sheary took a point-blank shot that Mason absorbed and froze at 3:41.
Highlight of the game
Cullen passed to Hornqvist at the top of the right circle, where Hornqvist attempted a shot but was shoved from behind. Cullen recovered the puck and shot through Mason, with it settling in the crease before the 40-year-old forward charged to tap it in for his 12th goal of the season and second in two games.
