"It was actually a pretty quiet first, which isn't always the nicest, but in this situation it was kind of nice to get my legs under me," he said.
Ekman-Larsson scored the game's only goal on a power play at 15:07 of the second period. Derek Stepan settled a pass from Clayton Keller at the left face-off circle with Ekman-Larsson sliding toward him and his stick in the air for several seconds. Stepan passed to Ekman-Larsson and his slap shot caromed off Markstrom and into the net.
"Give me the puck, maybe?" Ekman-Larsson said when asked about his obvious call for Stepan's pass. "I was about to turn away from him, but he made a good play there and it was nice to get one on my good friend (Markstrom)."
It was Ekman-Larsson's 10th goal of the season, the fifth straight season he has scored at least 10 goals. He leads all defensemen with 27 game-winning goals since beginning his NHL career in 2010-11.
Stepan has five points (one goal, four assists) in his past five games.
Arizona is 7-2-1 in its past 10 home games. The Coyotes have allowed two goals or fewer in eight of their past 13 games.
Coyotes coach Rick Tocchet liked the effort on the second half of back-to-back games.
"We had a long road trip and a tough place to play in Colorado," Tocchet said. "I liked the mental toughness of our team tonight."
