LOS ANGELES -- Justin Williams weaved his Game 7 magic, and Jonathan Quick slammed the door.
The duo combined to lead the Kings to a 2-1 win over the San Jose Sharks on Tuesday in Game 7 of the Western Conference semifinals, as Los Angeles moved one step closer to successfully defending last season's Stanley Cup victory.
Los Angeles awaits the winner of Wednesday's Game 7 between the Chicago Blackhawks and Detroit Red Wings.
The Sharks' season ended at Staples Center, a building where they lost four times in the series.
Williams scored two goals, giving him five goals and nine points in four career Game 7s, and Quick stopped 24 of 25 shots to deny a San Jose team looking to reach the conference finals for the third time in four seasons.
The Sharks finally solved Quick at 5:26 of the third period when Dan Boyle's shot from the middle of the blue line snapped the Los Angeles goalie's scoreless streak at home at 116:30 spanning back to Game 2.
However, the visitors couldn't score a tying goal on their seven shots thereafter or earn a call for a power play. Joe Pavelski had the best chance to tie it with five minutes remaining, but his point-blank shot of a Marc-Edouard Vlasic was along the ice and gloved by Quick.
Sharks goalie Antti Niemi was pulled for an extra attacker with 1:40 remaining. Logan Couture's shot from left of the slot was gloved by Quick with 1:19 left.
Niemi finished with 16 saves.
Things fell apart for the Sharks in the second period after they carried a majority of the play during the first 24 minutes. It started when forward Brent Burns interfered with Kings defenseman Robyn Regehr in the Los Angeles crease, the second of three straight San Jose minors committed far from the Sharks' net.
Los Angeles converted 1:25 into the resulting power play when Williams scored the first of his two middle-period goals by jamming the puck past the right skate of Niemi at 4:11 after Slava Voynov's point shot fluttered wide.
The goal capped a span of 18:54 between the first and second periods in which the Kings went without a shot.
The Sharks lost poise thereafter, committing turnovers one after another as Niemi stopped a Dustin Penner breakaway and gloved a Jeff Carter drive before Williams fired wide following a miscue by Sharks defenseman Scott Hannan.
Kings goalie Jonathan Quick stopped Patrick Marleau's turnaround shot in front and watched as a Matt Irwin drive trickled just past the far post. Moments later Williams capped a nifty passing play at 7:08 with his second goal, a blast from the right circle.
The Sharks outshot the Kings 5-3 and won 10 of 13 faceoffs in a tight-checking, defense-first opening period that finished scoreless.
Los Angeles bunched its three shots on goal during a 69-second span five minutes into the game.
A slow line change combined with a Boyle giveaway put the visitors on their heels when Dustin Brown's shot from the left circle started a dangerous sequence. Brown and Voynov took their turns firing away, but Boyle and fellow Sharks defenseman Brad Stuart blocked pucks before they could reach Niemi.
Joe Thornton high-sticked Mike Richards in front of the Los Angeles net, but the Kings' power play lasted only 21 seconds before Carter high-sticked San Jose penalty-killing forward Pavelski.
Boyle managed a shot on the resulting 21-second San Jose power play, but Quick kicked a rebound to the boards.
The Sharks had two other close calls: Thornton hit a pinching Irwin, whose shot from the slot was stopped by Quick, and Burns fired wide moments later from the left circle. San Jose's Bracken Kearns stole a puck deep in the Los Angeles end and tried to feed Adam Burish in the slot, but the pass sailed over the open San Jose forward's stick in the final minute of the opening period.
