Chase Briscoe Wins Las Vegas — But Kyle Larson & Denny Hamlin’s Afternoon May Matter More

LAS VEGAS — Chase Briscoe finally put an entire afternoon together.

On Sunday at Las Vegas Motor Speedway, the No. 19 Joe Gibbs Racing driver dominated the NASCAR Cup Series South Point 400 for his second win of the 2026 season. Briscoe led a race-high 175 of 267 laps, swept both stages, and then held off a desperate last-lap charge from points leader Kyle Larson to take the checkered flag.

It was the kind of performance Briscoe has looked capable of all year. The difference this time is that he actually finished it.

Briscoe won Stage 1 ahead of Christopher Bell and Stage 2 ahead of Austin Cindric, banking the maximum 20 stage points on the way to a 75-point afternoon. When the race came down to the final lap, Larson threw everything he had at him. The No. 5 car was on the limit, scraped the wall, and ended up making contact with Tyler Reddick in the final corner. Briscoe stayed clean and drove away to the win.

A week earlier at Kansas, Briscoe had given up the lead to Larson late and watched him drive off to victory. This time he slammed the door shut. That alone has to feel like a weight off his shoulders.

The points day was massive, yet the math is still sobering. Briscoe climbed from 123 points behind Larson to 84 back. That’s real progress in one afternoon, but it’s still more than a full race worth of ground to make up.

He’s shown race-winning speed for most of the season. The frustrating part is that performances like this should have happened more than twice. The Chicagoland win and now Las Vegas are the only times the speed has fully translated into a trophy. On pure pace, it feels like there should be a few more.

While Briscoe was the story of the day with the way he controlled the race, the championship picture took an even bigger hit in the early going — and it had nothing to do with the winner.

Both Kyle Larson and Denny Hamlin ran into serious trouble in Stage 1. How each of them handled it could end up mattering more than anything else that happened Sunday.

Larson started sixth and immediately knew the car was wrong. He was fading fast and fighting for any kind of grip. Crew chief Cliff Daniels made the call to bring him in under green for a lengthy pit stop to work on the right-front suspension. The stop cost him a lap. A caution a short time later handed him the free pass, and he was able to get back on the lead lap before the stage ended. He finished Stage 1 in 23rd, then spent the rest of the afternoon charging. Even after losing the brakes late, Larson still brought it home second.

That is championship-level problem solving. Bad car, long green-flag stop, a lap down, and he still leaves Las Vegas with a runner-up finish and the points lead intact.

Hamlin’s afternoon went the other direction. He started on the pole and led early, then stayed out on a different strategy and fought back up to fourth. With three laps left in Stage 1 he got loose in the high lane of Turn 4 and spun onto the apron. He missed the wall, but the splitter slammed hard into the track surface. He limped across the line 28th in the stage and never fully recovered, finishing 16th.Same stage. Similar early adversity. Completely different outcomes.

Larson’s lead over Hamlin is now 40 points. That gap felt manageable a week ago. After Sunday it looks a lot more like a real problem. Championships are often decided by these kinds of moments — not the days when everything is perfect, but the ones where something goes wrong and one driver limits the damage while the other watches the day slip away.

Briscoe deserved every bit of the spotlight for the way he dominated and finally closed. The speed has been there for months. Turning it into a win the way he did, especially after the Kansas heartbreak, is exactly what his team needed.

But when the season is over, Las Vegas might be remembered just as much for the contrast between Larson and Hamlin. One driver turned a potential disaster into a second-place finish and a bigger points lead. The other saw a strong start unravel with a spin and a 16th-place result.

Briscoe got the trophy he had been chasing. Larson got the kind of afternoon that wins championships. Hamlin got a reminder that time and points are both starting to run short.

The No. 19 team will celebrate a dominant win they earned. The rest of the garage just watched the championship picture tilt a little further in Larson’s direction.
