Erik Jones was leading on the final of 188 laps but the drivers behind him were getting antsy to make a move. Finally, Kyle Larson drove to the top lane to get around him and Jones followed him in an attempt to block.
Chastain, who was running third on the last lap, elected to remain on bottom lane and when those around darted up the track, he stayed low and held of Austin Dillon by 0.105 seconds to earn his second career win and second this season.
