Patrick Maroon scored the tiebreaking goal on a wraparound late in the second period, and the Anaheim Ducks beat the Los Angeles Kings 2-1 on Thursday night in the prelude to the clubs' landmark outdoor game this weekend.

Frederik Andersen made 30 saves for Anaheim as the Southern California rivals warmed up for their meeting at Dodger Stadium on Saturday with a physical, hard-hitting meeting dominated by the Ducks' defense.

Dustin Penner scored a power-play goal in the NHL-leading Ducks' 20th victory in 23 games. After a scoreless third period, Anaheim improved to 21-1-2 at Honda Center two days after its first home regulation loss.

Anze Kopitar scored early in the first period and Jonathan Quick stopped 19 shots for the Kings, who have lost four straight.
