Anaheim played without forward Rickard Rakell, who is day to day with an upper-body injury. Ducks coach Randy Carlyle said Rakell will not travel with them for the remainder of their six-game road trip.
"Credit to the guys that are here, it's not an easy task to go out and play in situations maybe that they have never been in their life in the NHL and playing that high in the lineup," Carlyle said. "Nick Ritchie, he played 21 minutes of ice time. That's the first time he ever would have played 21 minutes in the NHL. He's on power play, he's on penalty kill, he was a physical force.
"We have some growth taking place too in some young players, and that's been very, very enlightening. And we're real pleased with that, but points are what is most important."
Ritchie put the Ducks ahead 1-0 at 10:08 of the first period after Perry found him in the slot for a shot through traffic.
Perry has 10 points (two goals, eight assists) in his past 10 games.
Defenseman Cam Fowler also had an assist on the goal, his second in four games after missing the previous 12 with a knee injury.
The Kings, who are 2-6-1 in their past nine games, struggled to create quality scoring chances. Despite keeping the puck in the Ducks zone for more than two minutes in the middle of the second period, with the same Anaheim group on for two icing calls, Los Angeles had two shots, each from distance. Bieksa (3:11) was one of five Ducks caught on the ice for 2:07 or more during the stretch.
It wasn't until the final minutes that the Kings generated their best chances.
"They always say, 'Be ready for 60 minutes,' and it took us until the last minute," Lewis said.
Each team was playing the second game of a back-to-back. Los Angeles lost 3-2 in overtime to the Arizona Coyotes on Friday, when Anaheim lost 4-1 to the Winnipeg Jets.
