Kyle Busch did it again. He won the Brickyard 400 Sunday and the Xfinity Series race Saturday at the Indianapolis Motor Speedway–after winning both races last year. Busch had the fastest car in the week leading up to the race. And in the end, he needed that–and an iron will. He held the lead through a series of restarts near the end. Matt Kenseth was second, Jimmie Johnson third, Denny Hamlin finished fourth and Kyle Larson rounded out the top five.
