Kevin Harvick leads the Coca-Cola 600 at the one-quarter point — 100 laps of the 400-lap event at Charlotte Motor Speedway.
Johnson led early in the race before yielding the lead briefly to Brad Keselowski, who led three laps. At the 100-lap point, Johnson had led 75 laps and Harvick had led 22.
There have been only six lead changes among the same three drivers.
Also of note: Danica Patrick started fourth and was as high as second for several laps before falling back. At the 100-lap point, Patrick was running 13th.
Despite back spasms, Jeff Gordon is running a strong race, ranked seventh.
Kurt Busch, who is attempting to become the first driver to race 1,100 miles in the same day between the Indianapolis 500 (finished sixth) and the 600, was running 24th. Busch was forced to start from the 42nd position because he was unable to arrive at CMS in time for the mandatory driver’s and crew chiefs meeting.
Busch’s younger brother, Kyle, was forced to start from the back of the 43-car field due to driving a back-up car, having crashed his primary ride during Saturday’s second of two practice sessions. Kyle Busch had climbed up to 17th by Lap 100.
The first 108 laps were run caution-free until debris on the racetrack brought out the yellow flag to slow the field.
