Tyler Reddick of 23XI Racing scored a great finish in the South Point 400 at Las Vegas Motor Speedway on Sunday, but not without some struggles. Reddick began the race from fifth place and showed plenty of speed early in the first stage. He went on to place fourth at the end of the first stage and earn seven stage points. During the second stage, Reddick received a pit road penalty for having too many pit crew members of his team over the wall. Reddick spent the rest of the stage going coming from the back and to 11th. The No. 45 Toyota driver continued his ascent through the final stage, making it up to as high as third in the closing laps as he passed other drivers. On the final lap, Reddick tried to position himself to pass Kyle Larson on the final corner, but Larson smacked the wall, and Reddick could not avoid his car. Reddick spun through the infield grass into pit road, but still crossed the finish line to place third. With his best Las Vegas finish since March 2024, Reddick is now seventh in the Cup Series standings with five races left.

Kyle Larson nearly completed an incredible comeback to win the South Point 400 at Las Vegas Motor Speedway, but was one position short. Larson started sixth but struggled with handling early, forcing an extended pit stop in the first stage. After falling a lap down but getting back to the lead lap thanks to a caution, Larson went on to finish the first stage in 24th. In the second stage, Larson continued to move up through the field, passing other drivers until he finished the stage in 10th, gaining one stage point. In the final stage, Larson and his team improved the No. 5 car enough to compete for the win, as he continued to gain positions. Larson drove up to second and battled with Chase Briscoe in the closing laps. On the final lap, Larson positioned himself to make a move past the final turn, but got loose and hit the wall while Tyler Reddick clipped him and spun from behind Larson. Despite the damage, Larson still finished second and maintained the championship lead by 40 points over Denny Hamlin.

Chase Briscoe was the dominant driver of the South Point 400 at Las Vegas Motor Speedway. Briscoe began the race from fourth position and ran behind his teammates Denny Hamlin and Ty Gibbs until a lap 45 caution, when Briscoe stayed off of pit road. He gained the lead and never looked back through the rest of the first stage, winning it and gaining 10 stage points. In the second stage, Briscoe continued his dominance until green flag pit stops, when he lost the lead to other drivers who stayed off pit road. However, Briscoe's car was so fast that he passed everyone ahead of him and beat out Austin Cindric to win the second stage. Much like the second stage, Briscoe dominated the race until his green flag pit stop, but was chased by Bubba Wallace through most of the stage. Briscoe held off Wallace and maintained the lead until Kyle Larson challenged him for the win in the closing laps. The No. 19 Toyota driver stayed ahead of Larson, even after Larson hit the wall on the final lap, making a desperate move for position, and went on to claim his first Las Vegas Cup victory. After obtaining his second win of the 2026 season, Briscoe moves up to eighth in the Cup Series standings with five races left.

Ryan Blaney of Team Penske ran well throughout the South Point 400 at Las Vegas Motor Speedway, finishing in the top five. Blaney started 20th, but made up positions in the first stage to ultimately score stage points as he finished the stage in third. The No. 12 Ford driver continued to run inside the top five through most of the second stage outside of pit stops before finishing the stage in fourth. The final stage is where Blaney finally started to compete for the lead, as he did fight against Chase Briscoe early in the stage. However, he was unable to pass him and lost positions to other drivers, including Austin Cindric and Bubba Wallace. Blaney did go on to lead 10 laps in the final stage by running on the track while other drivers went to pit road before he eventually made his final stop of the race. He went on to regain positions through the race and placed fifth, earning his first top-5 finish at Las Vegas since March 2024. After 31 races this season, Blaney is now fifth in the Cup Series standings with five races left until the end of The Chase.
