"I'm getting more comfortable every period, every game," Guenther said. "The emphasis for me is just my start. I think I need to be better coming out of the gate, but once I get comfortable, I feel good out there, and I'm excited for what's to come."
After that, neither team seemed willing to let the other usurp its level of physicality.
"I liked our grit. I think we were physical, we played a good game," said head coach André Tourigny. "A little bit too many penalties, and our power play was not clicking, but if you look the way we worked, our effort, our physicality, that was pretty good.
"We need to make some plays and create more offense."
Anaheim forward Ryan Strome answered with 53 seconds to play in the period, scoring the eventual game-winning goal after Olen Zellweger threaded a shot-pass through the defense. Isac Lundestrom gave Anaheim a two-goal lead nine minutes into the third period, beating Vejmelka with a one-timer from the high slot.
Ducks forward Pavol Regenda also scored for the Ducks, notching his second preseason goal to put Anaheim ahead 1-0 17:25 into the first period.
Arizona plays next on Tuesday, Oct. 4 against the Vegas Golden Knights, and Tourigny said he's looking forward to being able to take the time and regroup with the club after playing four preseason games within a week of training camp kicking off.
