 15 laps to go here at Nashville. Chastain has the lead. Hamlin closing in. About half a straightaway ahead of third place Kyle Busch, who's soon going to have Kyle Larson on his back bumper. In turn two, the gap shrinks even more. Four car lengths throughout Chastain, barely hanging on against Hamlin. Denny Hamlin getting bigger and bigger in the one driver's rearview mirror now as they get into three. Hamlin's going to go up to the high side of the racetrack, try to get a good run. He's going to be right on the bumper of the leader of four.
