- AJ Allmendinger qualified 10th for the Grant Park 220. Prior to the start of the race, the field put on wet weather tires for the track conditions.
- Allmendinger was 11th when the first caution came out on lap three. Allmendinger told the team he had no traction compared to the cars around him, and lacked rear grip. The team stayed out under caution, and Allmendinger made his way up to ninth by lap 10. The second caution came on lap 12, and the team opted to stay out as the track conditions were not ready for slick tires. By lap 19, Allmendinger made it up to eighth where he would finish stage one.
- On lap 21, Allmendinger pitted under green to put slick tires on. As green flag stops cycled through, Allmendinger made his way back into the top 10, telling his team on lap 28 his car still lacked rear grip, as he took over seventh position on lap 29. Allmendinger went on to finish the second stage ninth as the caution came out on lap 44.
- NASCAR informed teams under caution the race would be shortened by 25 laps due to darkness. The No. 16 team changed its strategy and came down pit road on lap 45. Allmendinger would restart 24th with 27 laps remaining. He made his way up to 15th when the caution came out on lap 49 for a multi-car wreck. Allmendinger avoided the wreck, but told the team he may have suffered minor front-end damage after being shoved from behind into the corner. On lap 52, the No. 16 Chevy restarted 19th after several cars in the wreck kept their track position. Allmendinger moved quickly up to 15th by lap 57 when another caution came out. After the restart, he continued to gain track position, making it up to 12th by lap 62. The handling of Allmendinger’s car began to fade, as he fell to 17th where he would finish the race after one overtime attempt.
“We’re disappointed in our finish for sure. Our car wasn’t great; we lacked grip all day. Our strategy got thrown off when the race was shortened, and we just couldn’t get our car back up in the top 10. Congrats to my teammate, Justin Haley, on a good run today. Wish we could have been up there with him and had a better finish in our Bath Planet Chevy, but it just wasn’t our day.”
