FONTANA, Calif. (AP) -- Kyle Busch won at Fontana for the second straight year Sunday, holding off Kyle Larson, Tony Stewart and his older brother Kurt on a frantic two-lap sprint to the finish.
Kyle Busch capably blocked Larson and outlasted Stewart and Kurt Busch to win a wacky race featuring a track-record 35 lead changes and numerous tire problems. Kyle Busch is NASCAR's fifth winner in five races already this season.
Jimmie Johnson was comfortably in front when he blew a tire with seven laps left, and Jeff Gordon was in front until Clint Bowyer spun with two laps to go, setting up an overtime finish.
Larson, the 21-year-old rookie who held off Kyle Busch on Saturday to win the Nationwide race, posted the best finish of his career.
