PHILADELPHIA (AP) -- Good positioning means everything to Peter Mueller.
"I've been trying to get my body in front of the goalie more and it worked out good tonight," Mueller said.
"The first shot I hit [Biron] in the mask and it bounced right back to me," Mueller said. "I just did a kind of spin-o-rama and put it in."
Keith Yandle and Fredrik Sjostrom also scored for the Coyotes, who were coming off back-to-back road wins over the New Jersey Devils and New York Rangers. Phoenix has won four of its last five games, all on the road.
Yandle said that the Coyotes' confidence has been given a big lift the past three games.
"Getting wins against those teams ranks as a big accomplishment," Yandle said. "They're not easy games to go into."
The Flyers have lost eight of their last nine games at home (1-6-2) since opening the season 6-0 in Philadelphia.
After the game, the Flyers' players held a closed-door meeting for about 15 minutes.
"We talked about it as a team that we need to refocus and individually bring our best games to our team game every night," Flyers captain Jason Smith said. "We've got to play a lot better, compete a lot better, and capitalize a lot better. We can't be satisfied at working harder and losing games."
"We didn't have any hits after period number one," Phoenix coach Wayne Gretzky said, "We didn't want to go out and think that we played a really good period. I was proud of how they responded afterwards."
Richards made it 2-0 when he poke-checked the puck away from defenseman Ed Jovanovski near the blue line and skated in to score unassisted at 7:21 of the second period.
The Coyotes scored twice in 2 minutes, 31 seconds, to pull even late in the second period.
After Yandle hammered in a rebound at 17:07, Sjostrom took a backhanded pass from Shane Doan and scored short-handed from the front of the left circle at 19:38.
It was the first goal of the season for Yandle, who was recalled from the minors on Dec. 10.
Biron made 39 saves for the Flyers, who were outshot 42-28.
"I thought as the game wore on, they [Phoenix] dictated the style of game that they wanted to play," Flyers coach John Stevens said. "We didn't allow ourselves to dictate the style of play that we wanted to play."
