The Flames were shut out for the first time since losing 2-0 at Dallas on Dec. 18, and were held scoreless for the fourth time this season. Calgary had won the previous three meetings with Arizona by a combined score of 18-4.

Keller's 13th goal of the season came at 10:21 of the first period, and gave the Coyotes a 1-0 lead. Christian Dvorak skated up the wing with the puck and timed a pass across the Calgary zone to Keller. The Flames defender had fallen trying to block the delivery, but the puck reached Keller for a wrist shot into the net.

The Flames had a couple of quality chances miss just wide or over the net in the first.

Chychrun fired in a rebound that came out to him at 2:49 of the third period, after Dvorak tried to stuff the puck past Smith.

The Flames challenged the goal for goaltender interference, but it was upheld.
