Kevin Harvick scored his series-high seventh Cup win of the season Sunday at Dover International Speedway.

POINTS
Kevin Harvick clinched the regular-season title during the Dover Cup race.
The battle for the final playoff spot tightened. William Byron took the final playoff spot from Jimmie Johnson after losing it in Saturday’s race.
Byron leads Johnson by four points. It could have been more but a late two-tire pit stop gamble allowed Johnson to finish in third place, one spot ahead of Byron.
After the Dover Cup race, Johnson credited crew chief Cliff Daniels for the courage to make that call.
Matt DiBenedetto struggled Sunday. He is five points ahead of Byron and nine points ahead of Johnson.
“Dover killed us,” DiBenedetto said. “We were pretty horrendous both days.”
Also, Aric Almirola, Kyle Busch and Kurt Busch each clinched a spot in the playoffs via points.
