"You lose so much confidence when you're not scoring," said Korpikoski, who failed to earn a point in his first 16 games since coming to the Coyotes from the New York Rangers in the off-season. "It's a different game when you get the first one, everything slows down for you and you start to make plays with confidence again."
Robert Lang, Adrian Aucoin and Zbynek Michalek also scored to help the Coyotes snap a two-game losing streak. Matthew Lombardi and Scottie Upshall each had three assists for Phoenix in its fifth straight victory over Dallas.
"I thought we used our speed to our advantage and with Lombo up the middle, he was skating great and making plays," Upshall said. "We were tough in those tough areas and we got pucks out and battled around the net and that's where we found our goals."
Brenden Morrow and Mike Ribiero scored third-period goals for the Stars. "They capitalized on the chances they got," Stars coach Mark Crawford said. "Our impatience really showed. They got a couple of opportunities because we turned the puck over because of our impatience."
Aucoin extended the lead to 4-0 just 36 seconds later when Lombardi passed a rebound off Upshall's missed shot back to Aucoin at the bottom of the right circle.
That ended the night for Turco, who had allowed the four goals on 19 shots before he was pulled for the first time this season.
"We all feel like we let him down a little bit but he got the yank," Morrow said. "They were just a better team tonight," Dallas defenseman Stephane Robidas said. "Everybody was on a different program tonight and it wasn't good enough."
