It was also the first win for team owner Gene Haas since Stewart-Haas Racing shut down and was reorganized into the Haas Factory Team. Mayer has eight career wins now, including back-to-back victories at Iowa Speedway ... with two different race teams.

Mayer, 22, of Franklin, Wisconsin, held off Reiley Herbst in overtime in the June 2024 Hy-Vee Perks 250 at the Iowa Speedway. On Saturday Aug. 2, Mayer cruised to his second-straight win in the Xfinity Series race after a late restart.
