LOS ANGELES -- Winger Trevor Lewis and defenseman Jake Muzzin scored goals, goaltender Jonathan Quick made 21 saves as the Los Angeles Kings defeated the Anaheim Ducks 2-1 Wednesday and forced a seventh game in the Western Conference semifinal series.

Game 7 will be played Friday at Anaheim's Honda Center.

The Kings broke on top thanks to defenseman Jake Muzzin's third goal of the playoffs at 8:18 of the first period.

Muzzin, breaking down the slot, took a backhand pass from center Anze Kopitar and shoveled the puck past Anaheim goaltender John Gibson. Winger Marian Gaborik drew the secondary assist. It was the first time since Game 2 that Los Angeles opened the scoring.

The Kings doubled the lead on Lewis' fourth goal of the playoffs at 14:04 of the middle period. Lewis took what appeared to be a harmless wrist shot on a one-on-two rush from 40 feet out, but the puck trickled thru Gibson's pads and into the net.

The Ducks narrowed the margin to one on right winger Kyle Palmieri's second goal at 15:42 of the second period. Kings winger Tanner Pearson turned over the puck at his own blue line, and Ducks center Nick Bonino fed Palmieri, who sped around the Los Angeles cage and beat Quick with a wraparound shot.

Up 2-1 entering the third period, the Kings had an opportunity to regain a two-goal margin six minutes in, but center Jeff Carter's wrist shot off a two-on-one break hit the post to the left of Gibson and bounced to the corner.

The Ducks had an opportunity to even the game on a power play with less than seven minutes to go, but Quick made a glove save on a wrist shot by defenseman Cam Fowler.

Gibson stopped 21 shots while suffering his first loss of the playoffs.
