BOONE, Iowa (April 9) – Ricky Thornton Jr. showed the Midwest what he’d done all winter out West.The Chandler, Ariz., hotshoe scored the $1,000 payday in Boone Speedway’s season-opening Frostbuster event for Xtreme Motor Sports IMCA Modifieds.Nick Roberts and Jimmy Gustin split time at the front in the early stages of the 25-lap Fast Shafts All-star Invitational ballot qualifier while Thornton worked through traffic from a sixth row start.Thornton settled into fourth by the time caution slowed action on lap six. He raced the top side past Gustin for the lead on the 10th circuit while Mike Van Genderen mounted a charge running the high groove.As Thornton built a sizable advantage, Van Genderen shot past Gustin in the waning laps and chased down the leader.Thornton denied Van Genderen’s challenges to seal the win, his sanctioned 10th already this season. Gustin ran third. Kyle Strickler came from 16th starting to finish fourth.Jay Schmidt raced the low groove to victory in the 20-lapper for IMCA Sunoco Stock Cars.Norman Chesmore held the early lead as Schmidt worked into contention after starting ninth. He settled into second on lap seven and then made his way around Chesmore in traffic to take the lead on the next circuit.Despite heavy traffic late, Schmidt drove to victory ahead of Trent Murphy and Chesmore in a race that ran green to checkers.Jake McBirnie ran in the top five for the entire 20-lap distance of the Karl Chevrolet Northern SportMod feature. The only time he led was upon exiting turn four on the final lap.McBirnie surged past race-long leader Doug Smith on the low side to steal the victory. Brandon Spanjer ran third.Shannon Anderson made it look easy early and then held on late for the win in the IMCA Sunoco Hobby Stock main.From a second row start, Anderson slipped beneath John Watson on lap three to take the lead and quickly pulled away from the pack.A pair of late cautions bunched the field, but Anderson held on to take the win ahead of John Watson and Solomon Bennett.More than 120 cars were in the pits for the third of four Frostbusters.Feature Results Modifieds – 1.
