The Ducks prevailed (2-3) despite having only a few regulars in the lineup.
"They had a fairly strong lineup dressed, so I think our guys took it more as a challenge that we weren't going to outskill them," Anaheim coach Randy Carlyle said.
"They had more skill than we did in the lineup. That's no disrespect to our players. But the fact is we just tried to go out and play that workmanlike game and play with that tenacity that's necessary."
Gordon dug out a rebound from the corner and slipped a backhand under Quick's right pad at 19:20. Maroon scored on a wraparound at 19:31.
The Kings went 0 for 6 on the power play.
Kings coach Terry Murray said a reason for the loss was having several new players in the lineup together for the first time.
"You look at the (Ducks') lineup and you think they have a 'B' team right now and maybe you think it's going to be easier and maybe that's why we started the game the way we did," Gagne said. "But it's not an excuse even if it's preseason."
Ducks left wing Jean-Francois Jacques served a one-game suspension for an instigator penalty he incurred on Saturday against Vancouver.
