Arizona struggled to keep the puck in the offensive zone during the power plays and tested Carolina backup goalie Eddie Lack with just one shot.
"Obviously, we'd like to capitalize on that but (we've) been struggling for a while now," forward Max Domi said. "We've got to find a way to be better, keep practicing it and stick with it ... (It) starts with just getting in the zone."
Arizona has scored just three power-play goals in its past 34 chances.
• Center Peter Holland notched Arizona's lone goal when he crammed a loose puck that had gotten behind Lack into the net at 3:23 of the second period. Forward Anthony Duclair assisted on the goal to tally his first point since being recalled from the American Hockey League on March 1.
• Playing in his 300th game with the Coyotes, goalie Mike Smith stopped 33 shots, including all 14 he faced in the first period.
Smith didn't stop Derek Ryan's game-winning goal because the puck deflected off defenseman Jakob Chychrun's stick and then took a strange bounce off the crossbar and landed right in front of Ryan with Smith out of position.
"'Chych' made a great play to get a stick on it, and it just ended up coming on net," Smith said. "I just tried to fight it off but (it took an) unfortunate bounce … It's just frustrating. Giving up a goal like that with not too much time left in the game, it's tough to swallow a little bit."
Tippett liked what he saw from Smith overall.
"He was solid," Tippett said. "(He) saw a lot of chances and certainly gave us a chance to win."
Smith is just 11 games shy of tying Bob Essensa's franchise record for games played by a goalie.
