The first round of the inaugural In-Season Challenge produced a host of surprises at EchoPark Speedway south of Atlanta. Starting at the top, there were numerous upsets across the 32-driver field that was pared to 16 heading to the Chicago Street Race next week.

For example, first-seeded Denny Hamlin will go up against the No. 32 seed, Ty Dillon, on Saturday, while No. 7 Ryan Blaney will go up against Portage native Carson Hocevar, who is ranked 26th. The winner of the event, which will be crowned in the return of the Brickyard 400 next month, will receive a $1 million prize.
