LOS ANGELES (AP) — Jonathan Quick made 35 saves in his sixth career playoff shutout, and the Los Angeles Kings opened their second-round series with a 2-0 victory over the San Jose Sharks on Tuesday night.

Slava Voynov and Mike Richards each had a goal and an assist in the defending Stanley Cup champions’ 11th straight victory at Staples Center since March.

With yet another dominant playoff performance by Quick, Los Angeles opened the NHL’s fourth all-California playoff series with its fifth straight victory after an 0-2 start to its title defense.

The Kings’ Conn Smythe Trophy winner allowed just 10 goals in the six-game first round against St. Louis before frustrating the Sharks, whose superior speed and passing produced nothing.

Antti Niemi stopped 18 shots for the Sharks, who swept Vancouver out of the first round.

Game 2 is Thursday.

Opening a playoff series at home for the first time in 21 years, the Kings got just enough offense from Richards and Voynov, the Kings’ promising Siberian defenseman, who had the first multipoint playoff game of his short career.

Quick was on his formidable postseason game all night long, giving nightmares to the Sharks. San Jose scored 15 goals while sweeping third-seeded Vancouver, but Quick stopped every chance while the Sharks largely dominated play, particularly while outshooting Los Angeles 16-4 in the third period.

The Sharks and Kings are meeting in the postseason for the second time in three years, accentuating their already strong in-state rivalry. San Jose eliminated Los Angeles in 2011 on the way to the conference finals, but the Sharks’ years of steady excellence were surpassed by the up-and-down Kings when they raised California’s second Stanley Cup.

Penguins 4, Senators 1

PITTSBURGH (AP) — Paul Martin and Chris Kunitz scored power-play goals and Pascal Dupuis added his sixth goal of the playoffs and the Pittsburgh Penguins beat the Ottawa Senators 4-1 in Game 1 of the Eastern Conference semifinals on Tuesday.

Evgeni Malkin extended his points streak to seven games with a goal and an assist for Pittsburgh.

Game 2 is Friday night.

Tomas Vokoun stopped 35 shots to win his third straight start and top-seeded Pittsburgh never trailed.

Colin Greening scored for the Senators. Craig Anderson made 26 saves but Ottawa had no answer for Pittsburgh’s power play.

The Penguins are 9 of 24 with the man advantage through seven playoff games, best of the eight teams remaining in the postseason.

The Senators had the NHL’s best penalty kill during the regular season and turned aside 16 of 19 penalties against Montreal in the first round.

Pittsburgh was pushed to six games by the New York Islanders during a spirited first-round series in which the youthful Islanders had the Penguins on their heels at times.

Still, Pittsburgh advanced to the conference semifinals for the first time in three years behind the power play and a gutsy move by coach Dan Bylsma to bench top goaltender Marc-Andre Fleury and replace him with Vokoun.

The 36-year-old Vokoun made his 713th NHL start on Tuesday, but his first with the stakes this big.
