Viktor Arvidsson extended it to 3-0 at 12:36, scoring on a one-timer from the left circle before Grundstrom made it 4-0 at 13:48 with a wrist shot from the right circle.
"I've really been impressed with 'Grunny,'" Doughty said. "I think he's been playing great, playing hard. He's probably the hardest forward to play against when you play against our team because he's so physical and strong."
It was the second straight game Los Angeles scored four consecutive goals in the second period after also doing so in a 5-2 win against the New York Islanders on Tuesday.
"You look at the goals that we got; 'Kopi''s was a real nice touch play, but Carl's was a simple shot, 'Dewey' bullied his way to the net, so those were aggressive goal," Kings coach Todd McLellan said. "Shooting goals, and that's good for us to have in our game right now."
Hutchinson replaced Tarasov in the second after Columbus went down 4-0. Larsen said he didn't fault Tarasov for the first three goals.
"We put him in bad positions," Larsen said. "I felt bad for him because he deserved better."
Marchenko scored at 4:31 of the third period on a wrist shot from the left circle for the 4-1 final, ending a seven-game scoring drought.
"I don't think about goals," Marchenko said. "I start with scores (of the game)."

They also did so in 2015-16 (won 40 of first 66 games), 2009-10 (won 40 of first 67 games) and 1990-91 (also won 40 of first 69 games). … Marchenko's 17 goals ranks fourth in the NHL among rookies.
