Jack McBain scored, and Ivan Prosvetov made 33 saves for Arizona (28-40-13), which lost to the Kraken for the third time in eight days.
"I don't think [Seattle] found it tough," Coyotes coach Andre Tourigny said. "We didn't play as well as we can in those games, but we'll give them credit. They're tough to play against. They have a lot of pace, and they match a lot of the things we do really well. We're relentless and apply pressure, but they do as well. It was a tough matchup."
Schultz gave the Kraken a 2-1 lead on a breakaway at 14:56 of the second period. Just as Schultz came out of the penalty box, the Coyotes turned the puck over, allowing the defenseman to skate in and tuck a forehand inside the right post.
"I don't remember the last time I had a breakaway," Schultz said. "I was lucky enough it worked out. I know some guys do (practice breakaways), but I usually don't."
Matty Beniers made it 3-1 at 16:10, scoring glove side with a wrist shot from the left face-off circle on a rush.
McCann scored his 40th goal of the season to make it 4-1 at 14:39 of the third period. He beat Prosvetov glove side from the top of the left circle on a power play.
"I just needed a chance. There's a lot of guys in the NHL who don't get the opportunity," McCann said. "Not that they don't deserve it, sometimes that's just the way it goes. But it's obviously something I worked for."
