Mike Richards' wrist shot from the slot 1:35 into the extra session lifted Philadelphia over the Coyotes 4-3 and extended the Flyers' winning streak to four games on Saturday night.
Richards jumped out of the penalty box to score off a pass from Jeff Carter after the Flyers killed a Phoenix power play that extended 1:08 into overtime.
"Right over the blue line I was going to pass it right away," Richards said. "But I held on to it as long as I could. The (Phoenix) guy slid by and I took the shot."
Scott Hartnell, Mike Knuble and Carter also scored for the Flyers in a game punctuated by fluke goals. Philadelphia has won five of six.
"I knew when he (Richards) came out of the box, he was going to be firing," Carter said. "So I got it to him."
Daniel Carcillo, Martin Hanzal, and Todd Fedoruk scored for the Coyotes, who lost their season-high fifth straight game.
Mikael Tellqvist made 30 saves in his second start for the Coyotes. Martin Biron stopped 25 shots for the Flyers.
Carter pulled the Flyers into a 3-3 tie with 1:07 left in regulation when he deflected Richard's slap shot past Tellqvist.
"I'm more disappointed in the (missed) power play in overtime than I am in their score late in the game," Phoenix coach Wayne Gretzky said.
Carter's goal came after Fedoruk put the Coyotes ahead 3-2 at 14:46 of the third period when his wrist shot bounced in off Philadelphia defenseman Lasse Kukkonen.
Richards had nothing but praise for Carter, who went into the game second in the NHL with 13 goals.
"He is really playing unreal," Richards said. "He's doing a lot of good things on the penalty kill and on the power play. Right now he's doing everything he can to win us hockey games."
Knuble tied it at 2 with a power-play goal at 5:08 of the third. Standing with his back to the net, Knuble deflected Kimmo Timonen's shot past Tellqvist's glove side.
"We played a pretty solid game and let it slip away," Coyotes defenseman Ed Jovanovski said. "With Murphy's law, it just broke down and went the other way."
Phoenix went ahead with 51 seconds left in the second period on a fluke goal that was credited to Hanzal.
Zbynek Michalek's slap shot from just inside the blue line was knocked down by Luca Sbiza, but the Flyers defenseman got tangled up with Hanzal while falling down and his stick inadvertently swept the puck between Biron's pads.
Hartnell put the Flyers ahead at 6:18 of the first period with an unassisted goal. His shot from the left circle bounced off the skate of Michalek into the net.
Carcillo tied it for the Coyotes on a power play with 1:10 left in the period. It was his first goal in 15 games, dating to April.
Hanzal prevented Biron from clearing the puck cleanly from behind the goal, and Carcillo skated in and swept it into the open net.
