After the caution for Bobby Labonte's spin, the top 18 cars stayed out and it made for a frantic restart.
Several drivers jumped four-wide on the first green-flag lap, and Clint Bowyer emerged with the lead, followed by Brian Vickers and Denny Hamlin. Former leader Kasey Kahne, who had stayed out, fell back to fourth place.
Vickers briefly challenged Bowyer for the lead, but it was Hamlin who eventually caught the Richard Childress Racing driver and passed for the top spot at lap 25.
But Kyle Busch, who was the first car with four tires and had restarted 17th, zoomed up through the field like it was a Nationwide race and caught the leaders.
Busch caught his Joe Gibbs Racing teammate rather quickly and took the lead away. The competition caution flag is now out (lap 30), and everyone will pit for fuel.
As a reminder: If Busch wins, Sprint coughs up $3 million – one million each to Busch, his charity and a seriously lucky fan.
