Austin Dillon has won the NASCAR Nationwide Series championship, holding off Sam Hornish Jr. in a wild season finale Saturday.
Sprint Cup regular Brad Keselowski won the race after moving up 10 spots in the final few laps.
Dillon, driving the famed No. 3 for his grandfather, Richard Childress, held off Hornish by three points in the points standings.
Hornish looked as if he would overcome an eight-point deficit for much of the 200-lap race, but a lengthy caution late posed problems. Hornish dropped from third to ninth on the final restart with five laps to go, ending his chances at getting a title in what could be his final NASCAR race.
