Connor Mosack Finishes an Impressive Sixth at Chicago: Secures Third Top-10 After Career-Best Qualifying Effort in the NASCAR Xfinity Series


Connor Mosack returned to the streets of Chicago intent on wrapping up unfinished business from a year ago. In last year’s inaugural NASCAR Xfinity Series race on the 2.2-mile, 12-turn street circuit that loops around the city’s iconic Grant Park, Mosack qualified fourth and was a top-five mainstay until a carburetor issue thwarted his effort. In the second edition of Xfinity Series racing on Chicago’s streets, Mosack qualified a career-best third and then nabbed his third career top-10 by driving his No. 88 Porter Pipe & Supply Chevrolet Camaro to an impressive sixth-place finish.  

Like last year, Mosack was a regular among top-five. He held steady in fourth through the races’ first 16 laps and picked up third when he opted to stay out at the end of the first stage, leapfrogging third-place Ty Gibbs. When the race restarted on lap 19, it was three-time Australian Supercars champion Shane van Gisbergen in first and 2021 NASCAR Cup Series champion Kyle Larson in second. Mosack was third, with 17-time Xfinity Series race winner A.J. Allmendinger behind him in fourth.

Allmendinger squeezed past Mosack in turn one at the restart, forcing Mosack wide and dropping him to fourth. Three laps later, however, Allmendinger overshot turn six, nosing his car into the tire barrier and handing third back to Mosack.

When the caution flag waved on lap 24 to pull Allmendinger out of the tire barrier, it was time for Mosack to pit. With four fresh Goodyear tires and a full tank of Sunoco fuel, Mosack returned to the race in 18th, with those who had pitted at the end of the first stage now ahead of him. But Mosack was joined in this strategy by van Gisbergen and Larson, as well as others running in the top-10. This put Mosack 18th for the lap-26 restart. Undaunted, the 25-year-old racer picked up six spots to finish the second stage in 12th.

With other drivers having to pit at the stage break, Mosack lined up 10th for the restart. He passed John Hunter Nemechek and Larson to rise to eighth before a seven-car quagmire in turn 11 brought out the caution.

Cautions periods ended up consuming six of the final 13 laps, but even with the stop-start nature of the waning laps, Mosack made the most of the green-flag laps he did have, driving to sixth in his final three tours as van Gisbergen motored to a 1.287-second margin of victory over Gibbs. Larson was third, with Parker Kligerman in fourth and Jessie Love in fifth.

Connor Mosack driver of the No. 88 Porter Pipe & Supply Chevrolet Camaro for JR Motorsports:

“I felt like we were probably a third-place car all day. I rode between fourth and third there until we pitted. We kept up the speed out there, but were saving some for later and felt like we were in a really good spot. Never felt like we were quite as good as the 17 (Kyle Larson) or the 97 (Shane van Gisbergen).

“I felt like our pit strategy was the right one, but all those cautions and not having the green-flag laps really killed our strategy. That being said, the 97 was able to make it work, but we were probably in the wrong lane on a couple of restarts and just the line we were in didn’t go, and that kind of hurt our chances of getting back up there. Overall, it was a really fun race and I had a fun day, and grateful to be back on the streets of Chicago with Porter Pipe & Supply and JR Motorsports.

“This was probably one of the more stacked Xfinity Series fields on a road course in a long time, and that was part of the fun of the race. Even though we didn’t quite get the result we wanted, the showing was good and we had good speed, so I go home happy about that.”
