Jamie Benn made it 4-0 at 2:30 of the second period with a shot to the top right corner from left face-off circle on a power play.

“They had some good bounces there,” Kings forward Phillip Danault said. “They had some Grade A’s, some good chances. They buried them and got some good bounces as well. Nothing we can do there.”
The Stars swept the three-game season series against the Kings, outscoring them 13-3.
“We haven’t played good against that team at all so far. We haven’t shown what we’ve got,” Danault said. “Maybe it’s mental. We’ve got to be more ready. Obviously, this is a back-to-back, but we should be better. We were better in the third, so we should be playing that way the whole time.”
