The AMSOIL Championship Off-Road series delivered another action-packed weekend at Dirt City Motorplex in Lena, Wisconsin, where Jimmy Henderson and C.J. Greaves traded PRO4 victories while several championship contenders strengthened their title bids across Rounds 9 and 10 of the 2026 season.
Saturday’s Round 9 saw Henderson return to Victory Lane for his fourth PRO4 win of the season after taking the lead from Adrian Cenni midway through the race. Greaves charged through the field to finish second, extending his podium streak to five races, while Johnny Greaves completed the podium in third. In PRO2, hometown favorite Cory Winner converted the pole position into his first victory of the year ahead of Ryan Beat and Kyle Greaves. Joey Maciosek claimed his second straight PRO Lite win after Connor Barry suffered mechanical trouble, while Avery Hemmer became the sixth different PRO Spec winner this season with her first victory of 2026.
On Sunday, Greaves answered back in the PRO4 class, reclaiming the championship lead with a victory after Henderson had briefly moved ahead in the standings a day earlier. In PRO2, defending champion Keegan Kincaid returned to the top step of the podium, holding off Johnny Holtger by less than three-tenths of a second, while Cory Winner completed another strong weekend with a third-place finish. Matt Wood earned the PRO Lite victory after overtaking Michael Funk late in the race, and Nick Visser capitalized on a late caution to win a dramatic one-lap sprint in PRO Spec.
