Kurt Busch stormed into contention for a second Cup championship, holding off fellow Chase drivers Jimmie Johnson and Carl Edwards to win Sunday at Dover International Speedway. Edwards and Kevin Harvick share the points lead in the Chase for the Sprint Cup championship standings after three rounds. Harvick is seeded first because of a tiebreaker. Busch pulled away from Johnson after a late restart to win his second race of the season. Johnson, the five-time defending champion, was second and Edwards was third. Busch moved from ninth to fourth in the standings, only nine points out of first. Chase drivers Matt Kenseth and Kyle Busch were fifth and sixth. Harvick was 10th. Tony Stewart lost the points lead he built after winning the first two Chase races and finished 25th. Only 15 points separate the top eight drivers. The 400-mile race only tightened the leaderboard and no driver has emerged as clear-cut favorite. Non-Chase drivers filled four of the top-10 spots. Kasey Kahne was fourth, AJ Allmendinger was seventh, Clint Bowyer eighth, and Marcos Ambrose ninth.
