And while the Avalanche made the most of their power play, the Coyotes didn't back off and tied the score up 3-3 at 15:28 with a strike from Keller, who has now scored four goals and seven points (4G, 3A) throughout all four regular-season meetings against the Avalanche.
The Keller, Barrett Hayton, Nick Schmaltz line worked the Avalanche zone and finally cashed in. Juuso Valimaki collected a pass from Schmaltz at the boards and dropped a feed into the slot for Keller. With Rodrigues marking him, the winger turned off him and fired a backhanded shot that beat Georgiev on the near side for the equalizer.
The Avalanche and Coyotes each put up a shot during overtime, but neither team was able to score.
The game was decided in the seventh round of a shootout as both netminders were locked in. For Arizona, Schmaltz, Keller, Maccelli (failed shot attempt), Travis Boyd (failed shot attempt), Hayton, Lawson Crouse and Fischer were all denied by Georgiev, while Rodrigues, MacKinnon, Rantanen (failed shot attempt), Makar (miss), Compher and Denis Malgin all were held off by Ingram.
In the seventh round, Nichushkin curled into the slot, slowed down, chopped over the puck with his stick, took the puck to his backhand to pull Ingram to the right, then dragged it pack and tucked it past Ingram's right skate to secure the two-point victory for the Avalanche.
