Dahlin made it 4-0 at 6:42 of the second period with a shot from the right circle.
Zach Benson made it 5-0 at 14:17 when he collected a loose puck in tight and scored while falling to the ice.
“It was just a great pass by [Bryson], obviously, to give me that amount of time in front of the net,” Benson said. “Then obviously, he got a stick on my heels and when I was falling down, I just tried to elevate it and put it on net. I’m fortunate that it hit the back of the cage there.”
Tuch made it 6-0 at 4:30 of the third period after blocking a pass attempt in the neutral zone, and Greenway made it 7-0 on a rebound at the side of the net at 7:50.
“We started slow,” Kings defenseman Mikey Anderson said. “I thought when you compare it to the Edmonton game, we weren’t very clean today. I felt like breakouts started [on the] backend with us. I think we need to make a few more plays or at least put it in spots for the forwards to handle it. But yeah, things just didn’t go our way kind of the whole night, and we didn’t do anything to really change it at all.”
NOTES: Kings forward Carl Grundstrom left the game in the second period with a lower-body injury. There was no update. … Peterka scored his seventh game-opening goal of the season, tied for second-most in the NHL behind David Pastrnak of the Boston Bruins (eight). … Benson’s five goals are the fourth-most by an 18-year-old in Buffalo history, behind Phil Housley (17), Pierre Turgeon (14) and Rasmus Dahlin (nine).
