The dust settled on the South Point 400, and the only thing left to do was check the cars. Some fans worry about hidden tweaks or last-minute shenanigans, but the officials at Las Vegas Motor Speedway had a simple job. They looked at the No. 19 Toyota, and it passed with flying colors. There was no drama, no hidden penalties, and no reason to change the winner. Chase Briscoe took the checkered flag, and the rulebook agreed with him.
The Official Word on the Winner
NASCAR does not play games when it comes to the final check. After Briscoe held off Kyle Larson in a wild finish, the inspectors got to work. The process was quick and clean. Reporter Dustin Long posted the update straight from the garage area: “Post-race inspection is done here at Las Vegas. All clear. No issues.” That statement settled the debate instantly. Briscoe now has his second win of the 2026 season and his seventh career Cup victory. He controlled 175 of the 267 laps, sweeping all three stages to prove he was the best car on the track.
Larson tried everything to steal the lead on the final lap. He pushed hard, lost control exiting Turn 4, and hit the wall. That crash took out Tyler Reddick too, but Briscoe stayed steady. The win was never in doubt once the green flag dropped, and the inspection just made it official. As Long noted, “Chase Briscoe is the winner. We’re halfway through the Chase. On to Charlotte.” The series moves fast, and there is no time to dwell on what just happened.
Penalties Hit Two Teams Hard
While the winner walked away clean, two other teams got a wake-up call. NASCAR found real problems with the No. 92 car and the No. 88 car. The No. 88 team failed because one lug nut was not safe and secure. The No. 92 car failed for other inspection issues. Both teams must lose their pit-stall selection for the next race at Charlotte Motor Speedway. This is a big deal for strategy, even if it does not change the Las Vegas results. A pit-selection penalty is not a disqualification, but it sure hurts your chances next week.
The stakes were even higher for the O’Reilly Auto Parts Series. Brandon Jones in the No. 20 Toyota got disqualified entirely. NASCAR discovered at least four lug nuts that lacked safety or security. Jones dropped from 35th to 36th place and lost all his stage points. This cost him eight total points in the standings. It is a harsh lesson for any team that thinks they can cut corners. Safety rules are there for a reason, and NASCAR enforces them without hesitation. The rules are the same for everyone, from the Cup Series to the lower ranks.
Denny Hamlin finished 16th after an early spin, which hurt his championship hopes. He now trails Larson by 40 points in the standings. The 10-race Chase format does not use elimination rounds this year, so every point counts.
