Detroit and Boston lost in regulation earlier Saturday, opening the door for the Flyers to clinch a playoff spot with a win.
Thanks to sizzling right winger Wayne Simmonds, they did just that.
Simmonds scored two goals as the Flyers outlasted Pittsburgh's 'B' team, 3-1, at the electric Wells Fargo Center and earned the final Eastern Conference wild-card spot.
The Flyers will play the NHL's best team, the Washington Capitals, in a best-of-seven series that will start at the Verizon Center at a date to be announced. The Flyers won two of four games against the Capitals this season, splitting at home and on the road.
