Jimmie Johnson held off teammate Dale Earnhardt Jr. down the stretch to win for a record eighth time at Dover International Speedway.
The entire top 10 Sunday was made up of Chase for the Sprint Cup championship drivers.
Joey Logano, Jeff Gordon and Kyle Busch rounded out the top five. Cambridge native Matt Kenseth, who won the first two Chase races, finished seventh. He kept his points lead even as he fell short in trying to become the first driver to win the first three Chase races.
