Race
The race, the fifth in the season, began at 3:12 p.m. EDT and was televised live in the United States on Fox. The conditions on the grid were dry before the race while cloudy skies were expected. Jeff Hamilton, of Motor Racing Outreach, began pre-race ceremonies, by giving the invocation. Next, Night Ranger performed the national anthem, and the trio of Sean Hayes, Chris Diamantopoulos, Will Sass gave the command for drivers to start their engines. Pole position winner, Hamlin maintained the lead throughout the first lap, but was overtaken by Kyle Busch on the following lap. As the weather became worse for racing conditions, many teams adjusted their cars during the first set of green flag pit stops. On the 85th lap, Stewart claimed the lead from Kyle Busch. Shortly after, Stewart moved back into the lead ahead of Hamlin and Kyle Busch after pitting. The race ran 250 miles without incident, with the first caution on Lap 125 for rain. During pit stops, Stewart refused to pit, while Hamlin in the second position and a few others did. Also during the caution, Johnson, who had been in the top-ten for most of the race, began having problems with a potential oil leak, causing the smoke to run out of under the car. Afterward, the caution flag turned to a red flag, stalling the race because of the rain shower. Afterward, NASCAR decided the end the race, making Stewart the winner. Kyle Busch finished second, ahead of Dale Earnhardt, Jr., Harvick and Edwards. Biffle, Ryan Newman, Martin Truex, Jr., Kurt Busch, and Johnson rounded out the first ten positions. It was the first time a NASCAR race in the premiership had gone without an incident-related safety car since the October 2002 Talladega race.
