Kyle Busch is the leader at the halfway point in the Bass Pro Shops / NRA Night Race at Bristol Motor Speedway.

Busch has held the top spot since Lap 190 when he retook the lead from his Joe Gibbs Racing teammate, Carl Edwards. Edwards, the Spring winner at Bristol, led for 30 laps after taking the lead off pit road during a round of pit stops under caution.

The top 10 are Busch, Edwards, Kevin Harvick, Kyle Larson, Martin Truex Jr., Kurt Busch, Ryan Blaney, Jamie McMurray, Denny Hamlin, and Jeff Gordon.

There have been two cautions since the race restarted Sunday afternoon. The competition caution flew on Lap 85 before Regan Smith brought out the second caution on Lap 156 when he got into the Turn 2 wall.
