Brenden Morrow scored his 200th career goal for the Stars, who have won three straight. Jamie Benn also tallied, and Kari Lehtonen stopped 25-of-28 shots in the victory.
Dallas, which recorded more than one power play goal in just one of its 11 games prior to Friday, exploded for four goals with the man advantage on six opportunities. In the first 11 contests, the Stars had six power play goals total.
Sami Lepisto and Shane Doan scored for the Coyotes, who have yet to record back-to-back wins this season. Ilya Bryzgalov, making his 200th career appearance with Phoenix, was pulled after allowing three goals on 18 shots.
Dallas’ suddenly potent power play struck in the first period when Eriksson redirected a Mike Ribeiro pass high into the net at the 15:44 mark.
Richards scored twice in less than a two-minute span to open the second period, and his power play goal with 14:39 remaining in the middle frame put the hosts ahead, 3-0.
Phoenix finally cracked the scoreboard on Lepisto’s second tally of the season at 13:34, but Benn restored Dallas’ three-goal lead with a power-play goal 2 1/2 minutes later, and Eriksson’s second goal of the game with 2:51 left while on the man advantage made it 5-1.
On Eriksson’s goal, Matt Niskanen skated down the right side and made a nifty move to deke two defenders. He fired the puck across the ice to a streaking Eriksson, who redirected it into the net.
Doan scored a power play goal for Phoenix 2:28 into the third, but Morrow came back with a wrister from the slot to push the Dallas advantage back to four, 6-2, with 3:27 to play.
Only 25 seconds later, Adrian Aucoin scored for the Coyotes to cap the scoring.
