Kyle Busch raced to his 12th NASCAR Nationwide Series victory of the year and Austin Dillon maintained his hold on the championship lead with a third-place finish at Phoenix International Raceway.
Justin Allgaier passed Dillon on the last lap Saturday for second place, and it cost Dillon a point in the standings. Dillon takes an eight-point lead over Sam Hornish Jr. into next week's season finale at Homestead.
Hornish finished fifth.
Busch, meanwhile, needs a win at Homestead to match his career best 13-win 2010 season. He has a record 63 victories in the series.
A year ago, Busch went winless in the Nationwide Series. He has made 25 starts this year.
