"You ask big minutes out to those guys, to dig in and play with different partners, possibly play the wrong side and different matchups than you're accustomed to," Kings coach John Stevens said. "I thought that effort on the back end in terms of how far they dug in and how hard they competed was excellent."
Stevens did not have an update on Forbort, who left the dressing room on crutches and not putting weight on his right leg.
The Kings took a 1-0 lead at 9:29 of the first period on Mitchell's goal. Nate Thompson took a shot from above the left face-off circle that went off the end boards and sent the puck back to the crease for Mitchell to tap it past Bernier.
"It was wide open too, right in front of the net. I mean, it happens, but I haven't had many goals like that," Mitchell said.
Drew Doughty had an assist to extend his point streak to three games (one goal, three assists). It was Doughty's 59th point, matching his NHL career high from 2009-10.
Brown scored shorthanded to make it 2-0 at 12:32, beating Bernier with a wrist shot from the edge of the left circle.
Anze Kopitar and Martinez had the assists. Kopitar has two goals and three assists during a four-game point streak.
Kerfoot cut the Kings lead to 2-1 at 4:31 of the second when he scored top shelf over Quick's glove hand for his second goal in two games.
The Kings had killed 22 straight penalties before Kerfoot scored his fifth power-play goal.
Clifford scored on a wraparound two minutes into the third period to put the Kings up 3-1.
