Kyle Busch held off the field after a restart with three laps to go and went on to win the Buschy McBusch Race 400 NASCAR Cup Series race at Kansas Speedway.
The victory came on his birthday and gave him a second win on the weekend as he also won Saturday's NASCAR Truck Series event at Kansas.
It gives him a Cup victory for the 17th season in a row.
The win comes in the 11th race of the season while a year ago, Busch didn't win until the 34th event of the season.
The Joe Gibbs Racing driver led 20 laps Sunday in getting his second win at the 1.5-mile Kansas oval.
Finishing second was Kevin Harvick of Stewart-Haas Racing, who was also looking for his first win of 2021. The margin of victory was .336 seconds.
Third was Brad Keselowski of Team Penske, who started from the pole and led the first 64 laps.
Matt DiBenedetto of the Wood Brothers Racing team was fourth. Rounding out the top five was defending series champion Chase Elliott.
Kyle Larson appeared to be steaming toward his second victory of the season but a series of late-race cautions and a decision to not pit for tires during those cautions cost him his shot.
The Hendrick Motorsports driver led 132 of the 267 laps and held big leads for much of the final two stages.
He restarted with the lead with 10 laps to go but quickly was dropped back to third, where he restarted after the final caution. He ran into trouble on the final laps and wound up 19th.
Denny Hamlin appeared to have a great shot at depriving Larson of the win when he took the lead on a restart with 32 laps to go. But with 25 to go, he brushed the wall, blew a tire and hit the wall again as his chance to get his first win of the season ended.
The racing moves to Darlington, S.C. next weekend.
