Anaheim, early season leader in the Pacific Division, won its third in a row and remained the only NHL team with a perfect home record. The Ducks have captured all six of their outings on home ice and their seven road victories are the most in the league.
Ryan Getzlaf's power- play goal tied it with 4:24 left in the middle frame and Perry then beat the horn with his go-ahead goal.
Cam Fowler and Andrew Cogliano added scores in the third.
Hiller stopped 24 shots, as did Mike Smith for the Coyotes. Phoenix had won five straight and a regulation win would have vaulted the Coyotes over both San Jose and Anaheim into first place in the division.
