Ward and Sproul Score Wednesday Modified Qualifier Wins at Super Nationals

By Ben Deatherage BOONE, Iowa (Sept. 3, 2025) — Tim Ward raced his way to victory in Friesen Performance IMCA Modified Qualifier 1 Wednesday at Boone Speedway during the Speedway Motors IMCA Super Nationals fueled by Casey’s. The 25-lap contest locked the top four finishers into the inside row of Saturday’s Big Dance. Wyoming’s Bryson Yeager jumped to the front on the opening circuit, with Ward — the 2023 Super Nationals champion and Saturday’s Prelude winner — close behind. The two battled through heavy lapped traffic by lap eight, with Ward using a slower car as a pick to wrestle the lead away on lap 13. Two late cautions gave Ward, originally from Mesa, Ariz., and now calling Harcourt, Iowa home, clear track to race to the checkers. Two-time Sunoco IMCA Stock Car Super Nationals winner Dallon Murty made a spectacular charge from 22nd in the Darin Duffy-owned no. 99X to finish second. Six-time North Central Speedway track champion Aaron Johnson of Minnesota was third, while Yeager secured the final transfer spot in fourth. Hays, Kansas [Read More]

By Ben Deatherage BOONE, Iowa (Sept. 3, 2025) —Two-time Speedway Motors IMCA Super Nationals fueled by Casey’s champion Dallon Murty of Chelsea, Iowa, returned to victory lane Wednesday at Boone Speedway, winning Sunoco IMCA Stock Car Qualifier 1. The 25-lap contest locked the top four finishers into the inside row of Saturday’s Big Dance. Braden Richards led the opening lap after starting fourth before cautions slowed the pace on laps six and nine. On the latter restart, Richards got sideways and collected several cars, handing the lead to Murty. The Chelsea driver stayed out front the rest of the way, though he bobbled slightly coming to the checkers. Two-time 34 Raceway Stock Car champion Jeff Mueller made a last-lap run, but Murty held him off at the line. Murty started fifth, Mueller charged from 11th to second, reigning Jamestown Speedway Stock Car Stampede winner Jonny Carter of North Dakota came from 14th to third, and 2022 Marshalltown Speedway champion Michael Jaenette advanced from 15th to take the final transfer in fourth.
