Denny Hamlin led 163 laps, taking charge late and securing the win in the Food City 500, earning his first victory of the season.

"I feel good about my performance this year," Blaney said. "I think I'm well on my way to defending my title as Cup champion. And I think Phoenix Raceway has already defended its title as one of the most boring tracks on the schedule."

Kyle Larson dominated throughout the day on Sunday, sweeping the stages and leading 181 laps on his way to the win in the Pennzoil 400 at Las Vegas Motor Speedway.

Daniel Suárez surged late and edged Ryan Blaney and Kyle Busch at the line in a photo finish to win the Ambetter Health 400.

William Byron took the lead on lap 199 and held on for the win as Ross Chastain and Austin Cindric crashed as they approached the start/finish line.

Ryan Blaney passed Kyle Larson for second on lap 292 and held the position to claim the championship as Ross Chastain took the win at Phoenix. It is Blaney's first Cup championship.

Ryan Blaney passed Aric Almirola for the lead with 22 laps to go and pulled away to win the Xfinity 500 at Martinsville, winning his way into the Championship 4.

As Christopher Bell said, "I've never been more excited for a 'berth' in my life," Bell said. "And that will also be the case after I have children."

Larson won Stage 1 and held off Christopher Bell down the stretch to win the South Point 400 at Las Vegas.

"I already had my spot in the Round Of 8 sewed up," Byron said, "so I was out there just enjoying a leisurely Sunday drive. But things always get a lot less leisurely once I park the car for a NASCAR inspection."
