LOS ANGELES -- Winger Justin Williams and center Anze Kopitar scored two goals apiece, and goaltender Jonathan Quick made 25 saves as the Los Angeles Kings beat the San Jose Sharks 4-1 Monday, evening the Western Conference first-round playoff series at three games apiece.

The Sharks, who won the first three games before losing the past three, will return home for the decisive Game 7 on Wednesday.

Should the Kings win, they would become the fourth team in NHL history to rally from a 3-0 deficit to win a playoff series.

With Monday's game tied at 1 after two periods, the Kings sealed the win with three goals in the space of 2:46 of the third period. They took the lead on a Williams' second goal of the night at 11:56, and then Kopitar finished an odd-man rush at 13:27.

Kopitar added a power play goal at 14:42.

The Kings opened the scoring on Williams' third goal of the playoffs at 5:39. Defenseman Drew Doughty penetrated deep into the San Jose zone, and his cross-ice pass found Williams, who beat Sharks winger Joe Pavelski to the left post.

The Sharks had a golden opportunity to even the game when the Kings gave them a five-on-three advantage for 1:33 as defenseman Robyn Regehr and center Jarret Stoll drew penalties. San Jose was unable to mount any sustained offense, and the Kings held their one-goal margin.

San Jose drew even at 12:26 of the middle frame when center James Sheppard scored his second goal of the series. Sheppard deflected a shot from the point by defenseman Justin Braun that ricocheted off Regehr's skate and past a screened Quick. Winger Raffi Torres earned the secondary assist.

Kings defenseman Willie Mitchell suffered a lower-body injury midway through the second period and did not return, causing Los Angeles to finish the game with five defenseman.

San Jose goaltender Alex Stalock made 26 saves in his first start of the playoffs.
