It's a team effort coming to these places and having great race cars. I'm really excited to be starting up front, especially with my teammate Matt Kenseth on the front row with us."[11] He was joined on the front row of thegrid by Kenseth.[12] Bowyer qualified third, Kahne took fourth, and Truex Jr. started fifth.[12] Menard, Waltrip, Johnson,Ricky Stenhouse Jr., and Biffle completed the first ten positions on the grid.[12]
Kyle Busch started on pole, butMatt Kenseth led the first lap. Busch would then re-take the lead and lead the next 30 laps. The first caution waved on lap 24 whenPaul Menard blew an engine.Jimmie Johnson took the lead on the restart at lap 32, as Busch started to drift back in the outside line. Johnson led until lap 70 when the caution came out asJoey Logano hit the wall in the middle of a round of green-flag pit stops. Johnson had not yet pitted and would have to restart 17th behind the cars that had already made pit stops, giving the lead toDenny Hamlin.
Nonetheless, Johnson would draft back up to the front and pushJamie McMurray past Hamlin to take the lead on lap 94. The third caution waved on lap 101 asMartin Truex Jr. got sideways and collected Hamlin andJuan Pablo Montoya, also giving Busch some significant front damage. Truex would be the only one to retire following the crash. Johnson took the lead on the restart and held it all the way until the fourth caution waved on lap 126 for a crash involvingDavid Stremme,Aric Almirola,Greg Biffle, andA. J. Allmendinger in the tri-oval. Both Stremme and Almirola would retire from the race. Following the lap 133 restart, Johnson held the lead and was joined at the front by teammateKasey Kahne (who was subsequently passed by bothKevin Harvick andTony Stewart).
On lap 148, the fifth caution of the race came out for a large crash in the tri-oval. It started whenDenny Hamlin lost control near the entrance of pit road and turned up the track. He went head-on into the wall and was hit byA.J. Allmendinger andDave Blaney, almost causing Hamlin to flip.Matt Kenseth, who swerved while trying to avoid Hamlin, cut down and collectedJeff Gordon andDavid Reutimann, totalling six cars in all. The red flag was displayed for nine minutes to allow for cleanup and the race restarted on lap 154, with Johnson and Kahne jumping ahead of Harvick and Stewart. As they began lap 156, Johnson moved up to block a fast-approachingMarcos Ambrose and nearly lost the lead. However, Johnson blocked Ambrose out of turn two, which caused Ambrose to swerve and knock Kahne into the inside wall, bringing out another caution. Ambrose would subsequently have to pit for repairs as Johnson held the lead.
The race restarted on lap 160 (going past the scheduled distance of 160 laps and eventually ending after 161 laps) for a green-white-checker attempt with Johnson and Stewart holding the lead over Harvick andClint Bowyer. As the field worked through turn one,Carl Edwards was turned around byScott Speed in turn one, collectingMarcos Ambrose,Bobby Labonte,Joe Nemechek, andLandon Cassill. No caution was thrown for this wreck, which happened behind the leaders, and the field continued racing.

Harvick, Bowyer, andMichael Waltrip rounded out the top five.
