Kyle Larson became the first driver to clinch a spot in the NASCAR Championship Four on Sunday as he held off Christopher Bell and Kyle Busch for the win at Las Vegas Motor Speedway.

Larson survived an early slide that nearly put him into the wall. But he battled past playoff contender Bell and crossed the finish line in first place. He led 133 of the 267 laps and won Stages 1 and 2.

"Glad that we don't have to sweat through these next two races," Larson said.

The race turned back in Larson’s favor when he beat Bell and the rest of the leaders off pit road with 57 laps to go. Bell was playing catch-up in the latter stages of the race but couldn’t get around the No. 5 down the front stretch. He beat Bell by 0.082 seconds.

"I could see him coming in my mirror, for sure," Larson said of Bell. "Luckily, Christopher has always raced me clean. It could have gotten crazy there coming to the start/finish line."

Bell was in fifth place after the race and is currently on the outside looking in – two points behind Denny Hamlin.

"I don't know what else I could have done," Bell said. "I feel like that was my moment. That was my moment to make the final four and didn't capture it. It would have been nice to lock in."

It was Larson’s fourth win of the season.
