In Zilisch’s third win of the season, the 18-year-old also made history by becoming the youngest ever driver to reach four career wins in the Xfinity Series.

For Zilisch, the victory was revenge for last Saturday’s Xfinity race at the Chicago Street Course, where the 36-year-old van Gisbergen ran his 18-year-old teammate wide in Turn 2 to take the lead and win a two-lap shootout for the victory.
