Kyle Busch celebrated his 36th birthday by winning a two-lap sprint to the finish at Kansas Speedway.
He became the 10th different winner through the first 11 races of the NASCAR Cup Series season.
Busch had stalked Kyle Larson all day before beating him on a late restart to take the lead. Then, after another caution in the closing laps, Busch followed up his Truck Series win Saturday night with another trip to victory lane.
Kevin Harvick overcame a tire mishap on a late pit stop and took advantage of some chaos on the final restart to finish second. Brad Keselowski was third.
