Ryan Blaney dominated the inaugural NASCAR Cup Series race at Iowa Speedway on Sunday night for his first victory of the season and a spot in the playoffs. Blaney led four times for a career-high 201 laps, finishing 0.716 seconds ahead of William Byron for his 11th Cup victory. The defending series champion came into the race 12th in the standings. Blaney regained the lead on Lap 263 after taking just two tires on a caution-flag pit stop. He led the rest of the way, getting through lapped traffic as Byron tried to close. Blaney, whose mother, Lisa, is from Chariton, Iowa, won in front of a sellout crowd of an estimated 40,000 fans that included 80 of his friends and family.
