GRAND FORKS, N.D. (May 31, 2019) – The Buffalo Wild Wings NOSA Sprints introduced a new format on Friday, which included time trials that set up heat race line ups. It was the first time the NOSA Sprints had a time trial session since June 2006 when they gave drivers two laps on the clock to prepare them for the upcoming National Sprint Tour event that was coming to River Cities Speedway the following week.
