NEWTON, Iowa – Brad Keselowski took control with 35 laps left to win the NASCAR Nationwide Series race at Iowa Speedway on Saturday night.

The defending champion at NASCAR’s top level, the Sprint Cup Series, has won in his last three second-tier Nationwide starts.

Nationwide points leader Austin Dillon led a race-high 116 laps, but gave up a huge lead in the U.S. Cellular 250 after a late caution. Keselowski, the only Cup regular in the field, took control a few laps later for his second Nationwide victory in Iowa.

Sam Hornish Jr. was second, followed by Brian Vickers, Dillon and Kyle Larson.

Dillon led all but 43 laps in the first Iowa race in June, when he finished second to Trevor Bayne.

Dillon again had a dominant car Saturday. He led by as many as seven seconds — or more than a quarter of the 0.875-mile track — before a blown tire by Travis Pastrana drew out the flag and allowed the field to pit with 50 laps left.
