WILLIAM BYRON WINS IOWA CORN 350

William Byron held off a late push to claim the checkered flag in the Iowa Corn 350.  The driver of the Number-24 car edged Chase Briscoe by just over a second from Iowa Speedway.  Brad Keselowski, Ryan Blaney and Ryan Preece rounded out the top-five finishers.  The NASCAR Cup Series field heads to bendy Watkins Glen next Sunday as the regular season winds down.  There are only three races left until the playoffs.
