NASCAR Race Results

Ty Gibbs -- the 23-year-old grandson of former NFL coaching great and NASCAR team owner Joe Gibbs -- used late pit strategy and held off teammate Christopher Bell over the final 20 laps to win the NASCAR Cup Series race Sunday at Iowa Speedway.

Jackson Koivun, who left Auburn in June and won the 3M Open in only his third start, narrowly hung on to the 70th spot and goes from college to the postseason in only two months.
