SPARTA, Ky. (AP) - Rookie Austin Dillon took advantage of misfortune by Ricky Stenhouse Jr. and Elliott Sadler to the Nationwide Series race at Kentucky Speedway on Saturday.

Sam Hornish Jr. was second, followed by Brendan Gaughan, Drew Herring and Sadler, who reclaimed the season points lead from Stenhouse.

Dillon seemed destined for a runner-up run behind Sadler, who got an opening when Stenhouse collided with Eric McClure on pit road on lap 33. That essentially handed first place to Sadler, and he began pulling away in pursuit of his fifth win this season.

But Sadler encountered steering issues with 50 laps left and subsequent pit stops for corrections ultimately yielded the lead to his Richard Childress Racing teammate.

Sadler has a four-point lead over Stenhouse, who finished 17th. Dillon is 19 points back.

Dillon, who won the pole, completed a season sweep at Kentucky. He dominated the June race, leading 192 of 200 laps.
