Who won the NASCAR race today? Full results, standings from Iowa Corn 350 at Iowa

The Cup Series returns to the cornfield on Sunday for the Iowa Corn 350. It promises to be a captivating sight, filled with thrills, spills, and plenty of burnt rubber.

Iowa Speedway is a recent addition to the Cup Series calendar, only joining the fold last year. Ryan Blaney starred in the subsequent contest, racing to the front row in qualifying before landing stage points in the first and second stage en route to a dominant victory on the short track.

With the postseason on the horizon and playoff spots that much harder to find, a victory in farmland can do wonders for bubble drivers like Chris Buescher, Ryan Preece, Kyle Busch, and Ty Gibbs.
