Jimmie Johnson benefited from a late-race pit strategy to win Sunday's FedEx 400 benefiting Autism Speaks at Dover International Speedway.

Johnson, the six-time Sprint Cup Series champion, has now won at this one- mile, concrete-surfaced track 10 times, including victories in three of the last four races here.

Starting 14th, Johnson was not much of a factor until the last 50 laps. During a caution with less than 30 laps left, Harvick and Johnson opted not to pit and remained 1-2, respectively, in the running order. All others on the lead lap pitted.

Johnson pulled ahead of Harvick for the lead following a restart with 23 laps to go and then held off Harvick in two more restarts, including one for a green-white-checkered finish. Johnson beat Harvick to the finish line by 0.4 seconds for his fourth win of the season and the 74th of his Sprint Cup career. He led only the final 23 laps.

Kyle Larson finished third, followed by Kasey Kahne, Aric Almirola and Martin Truex Jr, who ran in front for a race-high 131 laps.

Jamie McMurray finished seventh, while Paul Menard Clint Bowyer and Jeff Gordon completed the top-10. Gordon won the most recent race at Dover last September.
