DOVER, Del. (AP) - Jimmie Johnson swept the season races at Dover International Speedway to accelerate his bid for a fourth straight Sprint Cup title.
      Johnson cut Hendrick Motorsports teammate Mark Martin's points lead Sunday with the victory - his fourth of the year - in the second of 10 races in the Chase for the championship.
      No winner of the second Dover race has ever gone on to win the Cup championship. If any driver can reverse that trend, it's Johnson. Much as he did in May, Johnson's No. 48 Chevrolet was out in front for the majority of the race.
      Chase drivers took nine of the first 11 spots. Martin followed last week's win at New Hampshire with a second-place finish. Juan Pablo Montoya was fourth and Kurt Busch fifth.
