It was Clint Bowyers race, right up until Jimmie Johnson, with a little help from teammate Dale Earnhardt Jr., nipped him at the line to win the Aaron's 499 at Talladega Super Speedway.  It was an exciting ending with 6 cars three wide at the line.   Johnson finished only 0.002 seconds in front of Bowyer, making it the closest margin of victory in a Sprint Cup Race since NASCAR began using electronic timing and scoring.   After Bowyer, Jeff Gordon was third, followed by Earnhardt and Kevin Harvick.   It was Johnson's 54 career win.
