Clifford and Amadio scored 1:23 apart to tie the game 4-4 after Blueger gave the Penguins a 3-2 lead at 9:26 of the third. Kopitar failed to score on a penalty shot with 8:31 remaining, and Jack Johnson made it 4-2 with 8:02 left.
Clifford cut it to 4-3 with a shot from the left face-off circle with 5:00 left, and Amadio tied it 4-4 on a wrist shot from outside the crease with 3:37 remaining.
"It had a little bit of everything," Kings coach Todd McLellan said. "Good start. We got into a bit of penalty trouble. They claw back as we expected. They're a very scrappy, competitive team. They don't go away, nor do we. We talked about that between periods. 'We got to respond here a little bit and push,' and I thought we did that late in the third. We didn't go away."
