Laps: 80

With 4 laps to go, Kyle Busch built a full second lead over Kyle Larson but Larson was closing the gap fast. With 3 to go, Busch and Larson had to navigate through lapped traffic with a total of 4 lapped cars bunched together all around them making it difficult for them to pass the cars. On the final lap, Larson had closed the gap to 0.35 seconds and attempted to pass Busch on the inside in turn one trying to use the slide job but failed to get in front of Busch. The two made contact with Larson putting Busch in the wall in turn 2. Down the backstretch, Larson took the lead from Busch heading into turn 3. Busch sent the car hard into turn 3 hitting Larson in the rear hard causing Larson to go sideways trying to save his car and Busch hit the wall again by driving his car deep into the corner. Busch ended up taking the win over Larson in one of the most memorable finishes in NASCAR history.
