After a clean start, pole-sitter Kasey Kahne took an early lead over Clint Bowyer (who led the first lap), and drivers seemed to be managing their equipment until the scheduled competition caution at lap 30.
But on lap 11, Bobby Labonte lost control of his car in Turn 4 while running 22nd and spun into the frontstretch grass. He had little damage, but it caused the first caution of the day and offered the opportunity for some cars to come down pit road.
Leader Kahne was one of 18 cars to stay on the track, but others like second-place Kyle Busch and Jeff Gordon came onto pit road and took four tires.
Kurt Busch was the first of the cars off pit road, followed by Ryan Newman. Each of those cars took two tires apiece.
When the race goes green, there should be about 15 laps until the competition caution and the next pit stop.
