This was the first year the NASCAR Xfinity Series had the playoff format where only four drivers can win the Championship in the end. The four drivers that would contend for the Xfinity Series championship would be Elliott Sadler, Justin Allgaier, Daniel Suárez, and Erik Jones. Jones would be the only rookie to compete for the Championship. Allgaier was the only winless driver to compete for the Championship. All four drivers would get in by points.

With 49 laps to go, Justin Allgaier took the lead from Suárez. While he took the lead, Elliott Sadler hit the turn 2 wall which dropped him back one spot. With 44 to go, Erik Jones took the lead. With 42 to go, the 6th caution flew for debris. Daniel Suárez won the race off of pit road but Aric Almirola and Ryan Blaney did not pit and Almirola led the field to the restart with 37 to go. Suárez immeadietly passed Almirola for the lead. Soon Suárez had built a sizeable lead over Erik Jones and Justin Allgaier but Jones reeled in Suárez with around 16 to go and was all over his rear bumper. But Jones hit the wall with 15 to go causing him to lose momentum. He closed in on Suárez again but hit the wall again two laps later. Jones was closing in on Suárez again when the 7th and final caution flew with 10 laps to go when Ray Black Jr. spun off of turn 4. This put pressure on crews to make the perfect stop for their driver. Everyone took four tires but Sadler's team took two tires and they won the race off of pit road putting them in front of the Championship 4. Allgaier's crew had a mess up as the jackman slipped going to the left side of the car which lost Allgaier two spots in the process. Cole Whitt stayed out and he led to the field to the restart with 3 laps to go. He quickly stacked up the field including Allgaier and Jones who were behind Whitt and Sadler took the lead. Suárez immeadietly went to Sadler's outside and Suárez was the new leader with 3 laps to go. Sadler tried to catch Suárez but couldn't and Daniel Suárez won the race and the NASCAR Xfinity Series Championship. Behind them, Alex Bowman crashed on the front stretch after contact with Bubba Wallace. Suárez became the first Mexican born driver to win a NASCAR Championship in the top 3 Series of Trucks, Xfinity, and Cup. This would be his first and only Championship. Ty Dillon, Elliott Sadler, Ryan Blaney, and Austin Dillon rounded out the top 5 while Justin Allgaier, Kyle Larson, Brendan Gaughan, Erik Jones, and Aric Almirola rounded out the top 10.[4]
