Adrian Kempe put the Kings up 2-1 at 9:58 of the second period. He scored on a wrist shot from the left circle off the rush for his 12th point (five goals, seven assists) during an eight-game point streak, the longest of his NHL career.
Eller tied it 2-2 at 18:03 on the Penguins’ first short-handed goal of the season. He picked up the loose puck after Fiala misplayed it in the neutral zone and scored on a wrist shot from the high slot.
Pittsburgh swept a three-game California road trip for the second time in franchise history, having done so in 1996-97.
“I know it was an ugly win,” Penguins coach Mike Sullivan said. “I don't think we were at our best. … But I just thought we kept competing. It's obviously a great road trip for us. I think it's something that we can build on.”
