The 25-year-old Custer from Ladera Ranch, California, led all 25 laps en route to being named the inaugural victor of the Xfinity Series' Chicago Street Course event due to inclement weather.
The remainder of the Xfinity Series' inaugural event at the Chicago Street Course will resume on Sunday, July 2, at 11 a.m. ET on USA Network after inclement weather delayed and canceled the planned conclusion of the event on Saturday, July 1.
