Kyle Busch won the NASCAR Camping World Truck Series and Nationwide Series races at Auto Club Speedway in Fontana. He's already made history by becoming the first driver to win two NASCAR races in the top three divisions in the same day.
He can become the first driver to win a NASCAR Truck Series, Nationwide Series and Cup Series race at the same track on the same weekend if he can win the Auto Club 500.
He says he has a top five Cup car, and his biggest challenge awaits him.
When asked if he thinks he can sweep the NASCAR races in Fontana, Busch said he didn't know.
"The Interstate Batteries Camry on that side was decent, it wasn't the best (Saturday) but I'm sure Steve (Addington, Busch's crew chief) is thinking about it and I'll call him after this race to see what I learned and talk to him a little bit and see if we can't figure something out to make it a little better for tomorrow," Busch said.
For the record, only two drivers have won NASCAR races in two of the top three divisions in the same weekend at the same track. Greg Biffle did it at Phoenix in October 2001 and Busch did it at Phoenix in 2007.
