Jimmie Johnson dominated again in a Chase race, sweeping the season races at Dover International Speedway to accelerate his bid for an unprecedented fourth straight Sprint Cup title. Johnson cut Hendrick Motorsports teammate Mark Martin's points lead Sunday with the victory - his fourth of the year and 44th overall - in the second of 10 races in the Chase for the championship. “I'm pretty sure that dude is Superman,” Martin said. 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 400-mile race. “I certainly hope that our performance today scares some people and affects them in a way that benefits us,” Johnson said. 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. Matt Kenseth was the highest non-Chase driver at third. Martin holds a 10-point lead over Johnson heading into next week at Kansas Speedway. “This team is really on a roll right now,” Martin said. Other Chase driver results saw Jeff Gordon finish sixth, Kasey Kahne was eighth, Tony Stewart ninth and Ryan Newman 10th. Carl Edwards was 11th, Greg Biffle 13th, Brian Vickers 18th and Denny Hamlin 22nd. “It's just two races,” Martin said. “I still say that there's 12 in and 12 can win. It might be a challenge for a couple of the ones toward the end of the back.” Johnson, who tire-tested in August at Dover, won from the pole. He led 298 laps when he won at Dover in May and added another 271 on the 1-mile concrete track Sunday. Johnson won for the fifth time at Dover.
