Heinen tied it 2-2 at 8:57 with Anaheim's first power-play goal of the season, scoring off the rebound of Cam Fowler's slap shot for his second goal in as many games. The Ducks were 0-for-17 on the power play.
"You'd like to at least grab a point if you can't get the win, and with that power-play goal, we were excited to finally get one in the net," Anaheim coach Dallas Eakins said. "So it's a pretty empty feeling right now."
Dvorak tied the game 1-1 at 7:43 of the second period when his shot from along the goal line deflected off Shattenkirk's left skate. It was the first goal for the Coyotes in 148:42.
"It was a good period for us, and it obviously got us going and gave us momentum," Dvorak said. "I thought we had a lot of energy. Obviously, we knew it was a big game for us, we didn't want to lose again here at home."
