 Bush will work the top side. Down at the bottom is Hamlin. They're sitting right behind A.J. Allmendinger. Which way will Bush go? I think he'll try to get to the top, but moving up to block is Allmendinger. Kyle Bush has got the bottom open. If he wants it, we'll see if he wants to take it here. No. He'll back off into the corner, and he'll hold on to that spot. Meanwhile, up front, Blaney closes down ever so slightly on the leader. 45 laps to go here at Nashville. Three car lengths. The lead, Blaney, as he trails Chastain into turn one.
