Tyler Reddick swept past defending champion Chase Elliott on a curve to claim Sunday’s Kwik Trip 250 in the NASCAR Cup Series at Road America.
Elliott has dominated the races at Elkhart Lake.
The 26-year-old Reddick finished a little over 3.3 seconds ahead of Elliott.
He becomes the fifth first-time winner on the Cup Series this season and the 13th different driver to claim a victory in 18 races.
Ty Gibbs passed reigning NASCAR Cup Series champion Kyle Larson on the final lap Saturday to win the Xfinity Series Henry 180 on the same road course.
