Dover, DE (My Sportsbook) - Jimmie Johnson gave his bid for a record fourth consecutive Sprint Cup Series championship a shot of momentum by winning Sunday's AAA 400 at Dover International Speedway.

Johnson put on a dominating performance at "The Monster Mile" by leading 271 of 400 laps. He easily held off current points leader and Hendrick Motorsports teammate Mark Martin by nearly two seconds at the finish for his fourth victory of the season.

"I certainly hope that our performance today scares some people and affects them in a way that benefits us," Johnson said.

Johnson, who won at Dover in May, scored a season sweep here for the second time in his career. He also won both races at the one-mile, concrete-surfaced track during his 2002 rookie season. Johnson has now won at Dover five times, which is the most among active drivers.

"For me, this is one of the closest tracks to off road racing that we have on the circuit," he said. "You're virtually airborne off in each corner, so I think that helps me some and relates back to the vehicles I drove growing up."

With the victory, Johnson moved to within 10 points of Martin, who finished second.

"I'm really happy with the result," said Martin, who won the first race in the "Chase for the Sprint Cup" last weekend at New Hampshire. "It wasn't a car that could contend to win.

Matt Kenseth, who failed to make the Chase for the first time this year, finished third, while title contenders Juan Pablo Montoya and Kurt Busch completed the top-five.

"With a top-five, I can't complain," Montoya said.

Montoya is now 65 points behind Martin, while Busch trails by 75 markers.

Jeff Gordon finished sixth, followed by A.J. Allmendinger, Kasey Kahne, Tony Stewart and Ryan Newman.

Eight drivers in the top-10 finishing order at Dover are in the Chase.

Denny Hamlin finished the worst among the Chase contenders with a 22nd-place run. Carl Edwards came in 11th, while Greg Biffle, the defending race winner, was 13th and Brian Vickers 18th.

Hamlin also took the biggest tumble in points, dropping from third to sixth (-108).

Just after a restart on lap 31, Joey Logano was involved in a horrifying crash. Logano checked up and was tapped from behind by Tony Stewart, causing the 19-year-old rookie to spin on the backstretch. His car then slid up the track before Reed Sorenson rammed into the side of him. Logano's car flipped eight times before it came to rest. He was not injured and able to exit the car under his own power.

"It just scared the heck out of me," said Logano, who finished 42nd. "It started rolling, and I was in there saying, 'please make this thing stop.' It wouldn't, and it just kept going and going."

Robby Gordon and Martin Truex Jr. were also involved in the incident, which forced NASCAR to stop the race for 24 minutes to allow for track cleanup efforts.

"I hit him square, but I couldn't do anything," Stewart said to his team over the radio during the red-flag.
