Jimmie Johnson gained ground on Matt Kenseth in the Chase for the Sprint Cup championship after winning at Dover International Speedway for a record eighth time.
Johnson put on a dominating performance in Sunday's AAA 400 by leading 243 of 400 laps around this one-mile, concrete-surfaced racetrack. He had been tied with Bobby Allison and Richard Petty for most wins here with seven each. Johnson also claimed his fifth victory of the season and the 65th of his Sprint Cup Series career.
With the win, Johnson trimmed Kenseth's lead from 18 points to eight. Kenseth finished seventh at Dover after his victories in the first two Chase races -- Chicagoland and New Hampshire.
Dale Earnhardt Jr. bounced back from a pit-road blunder early in the race to finish second. Earnhardt came towards the entrance of pit road too fast and overshot the commitment cone, forcing him to make another lap around before making his stop.
During the last round of pit stops with less than 30 laps to go, Earnhardt took four new tires while Johnson opted for two tires. Earnhardt charged from fourth to second on the final restart. He ended up finishing 0.5 seconds behind Johnson.
Joey Logano finished third, while Jeff Gordon and Kyle Busch rounded out the top-five. Busch is now 12 points behind Kenseth.
Kevin Harvick placed sixth. Ryan Newman, Greg Biffle and Clint Bowyer were eighth through 10th, respectively. The top-10 finishers are all in the Chase field.
