Gavrikov put the Kings back ahead 2-1 at 9:32 of the second period on a wrist shot from the blue line.
Kopitar extended it to 3-1 at 11:52 with a wrist shot from the right circle off a pass from Kempe.
“Really nice goal off the forecheck,” Hiller said. “Part of our game plan was to forecheck. We didn’t do a lot of it, but that one was to a T.”
Kopitar pushed it to 4-1 with a power-play goal at 19:08, redirecting the puck in after Mrazek broke up Kempe’s centering pass.
It was Kopitar’s 1,199th career point (415 goals, 784 assists) in 1,360 NHL games.
“We were looking out there for him,” Kempe said of Kopitar. “He had some good looks and it was close (to reaching 1,200). Obviously, look forward to that next game, but it was a close one tonight. He was hot out there.”
Phillip Danault made it 5-1 at 5:47 of the third period, scoring off a pass from Trevor Moore.
Kevin Korchinski cut it to 5-2 at 14:16, scoring in his second straight game.
“As a young up-and-coming guy that can shoot a puck like he did tonight and last game, we got to make sure he has more opportunities to do that in the offensive zone and not be chasing guys around the D-zone,” Richardson said.
Trevor Lewis tipped in Dubois’ shot at 17:10 for the 6-2 final.
