Six players scored, and Tristan Jarry made 39 saves for Pittsburgh (3-0-1), which has outscored opponents 18-5 in three home games. Jarry has allowed five goals on 104 shots (.952 save percentage) in three starts this season.
"I think I just want to get better every year," Jarry said. "Every year, I want to take a step. Every year I come in, I'm a little bit more mature. I have a little more, I guess, games under me. So just being able to start, knowing what to expect, it does nothing but help."
Cal Petersen surrendered three goals on nine shots in the first period for Los Angeles (3-3-0), who had won three straight. Jonathan Quick replaced Petersen and made 22 saves over the final two periods.
"I guess with Cal, there's no secret we have to get him going," Kings coach Todd McLellan said. "He has to play like he can play. He's an NHL goaltender. He's an outstanding young man that's played extremely well at this level. We're trying, just like we would with forwards and defensemen, to get him to where he can be. He has to be better."
