INDIANAPOLIS — Brad Keselowski became the first driver to celebrate a victory at Indianapolis Motor Speedway in NASCAR's second-tier Nationwide Series.

Elliott Sadler was fuming, certain he should have been celebrating instead.

Keselowski took the lead when Sadler was penalized for jumping a late restart Saturday, then held on to win a controversial finish to the inaugural Nationwide race at the historic 2.5-mile track.

Sadler passed Keselowski on a restart with 18 laps to go, but officials ruled Sadler went too early and black-flagged him.

Sadler stayed on the track for several laps, apparently hoping officials would reconsider the penalty, before finally coming in with 12 laps to go and giving up the lead to Keselowski.

An agitated Sadler said Keselowski spun his tires on the restart — a brief loss of traction that would slow Keselowski down — and Sadler said he had no other choice but to surge forward because cars were stacking up behind him.

"It's so wrong to penalize me for a mistake they made," Sadler said to his crew over the radio. "NASCAR just took the championship away from me."

Sam Hornish Jr. was second.

Kasey Kahne of Enumclaw earned the ninth Nationwide pole of his career but finished 25th. Tayler Malsam of Seattle was 29th.

Notes

• Sadler leads the Nationwide standings by a point over Austin Dillon.

• Denny Hamlin won the pole for Sunday's Brickyard 400, a NASCAR Sprint Cup Series event at Indy.

Hamlin turned a lap of 182.763 mph. Carl Edwards qualified in second.

Greg Biffle of Vancouver, Wash., will start in fifth, and Kahne will start in 15th.
