Kimmo Timonen tied the game with 9.5 seconds left in regulation and assisted on Ruslan Fedotenko's game-winner in overtime, as the Philadelphia Flyers rallied past the Washington Capitals, 5-4.
Timonen had three assists for the Flyers, who have won two in a row and sit two points behind the New York Rangers and Islanders for the eighth spot in the Eastern Conference.
Claude Giroux had a goal and two assists for Philadelphia, which took two of three from Washington this season. Maxime Talbot and Matt Read also lit the lamp. Talbot left the game late in the second period with a lower-body injury.
Ilya Bryzgalov made 25 saves for the victors.
Marcus Johansson had a goal and an assist for the Capitals, who are four points behind the Winnipeg Jets for first place in the Southeast Division. Nicklas Backstrom, Mike Green and Alex Ovechkin also lit the lamp.
Braden Holtby stopped 29-of-34 shots in defeat.
"It's tough obviously. It's bad, but we needed to make more of an effort on our part the last couple of minutes there," Backstrom said.
Trailing by two, 4-2, Giroux got the Flyers within one at the 12:48 mark of the third period.
Philadelphia pulled Bryzgalov with about 1 1/2 minutes left for the extra attacker. Timonen's one-timer from the point beat traffic in front and got past Holtby, making it 4-4 with 9.5 seconds left.
Fedotenko scored the game-winner 1:34 into overtime as Timonen set up him up with a perfect crossing pass to cap off a remarkable comeback.
"We got control of the puck a little bit in the offensive zone and I should have had a chance to give Kimmo (Timonen) a breakaway pass. I missed it but we still had possession of the puck," Fedotenko said. "We started moving around and I got back. Kimmo gets opened up again and I just give it to him across the ice and go back to the net pretty hard. He saw an opportunity to give it right back and almost a backdoor tap-in."
The Capitals drew first blood at the 4:29 mark of the first period. Jack Hillen's shot from the point was deflected in by Backstrom.
Talbot tied the game at the 10:26 mark. Timonen threw the puck off the back boards and Zac Rinaldo redirected the puck to Talbot, whose shot from the slot beat Holtby.
Read gave the home team a 2-1 lead at the 14:55 mark. Read took a pass from Giroux and went in on a breakaway.
Green scored on a breakaway with 1:18 left in the middle stanza to make it a 2-2 game.
A turnover by Giroux in his own zone led to Washington's third goal. Johansson gathered the loose puck and beat Bryzgalov on a shot from the high slot, making 3-2 at the 6:22 mark of the third.
Just 26 seconds later, Ovechkin's one-timer from the left circle gave the Capitals a two-goal cushion.
