Knoxville Raceway in Knoxville, Iowa, will host the USAC AMSOIL Sprint Car National Championship Avanti Windows & Doors Corn Belt Clash on May 29–30, timed to coincide with the National Sprint Car Hall of Fame induction weekend.

The two-night short-format national sprint car event will race on Knoxville’s half-mile oval. The Friday program features a 25-lap main paying $10,000 to the winner; the Saturday finale is a 30-lap feature paying $15,000 to the winner. Pits open at 3 p.m. CT each day and hot laps are scheduled for 6:30 p.m. CT each night. The weekend will stream live on FloRacing and advance tickets are available at KnoxvilleRaceway.com.

Series leader and defending USAC Sprint Car National Champion Kyle Cummins tops the standings with 1,058 points after wins at Terre Haute in April and at Eldora in May. Mitchel Moles (970 points) and Justin Grant (969 points) are entered; Grant is a past Knoxville winner and is chasing career USAC wins No. 98 and No. 99.

The entry list also includes past Knoxville USAC winners Brady Bacon (a five-time Knoxville winner), Jake Swanson and Kevin Thomas Jr. Organizers say seven top-10 drivers remain in search of their first Knoxville triumph, including Cummins, Moles, Logan Seavey, Briggs Danner, Chase Stockon, C.J. Leary and Robert Ballou.

Team AZ/Curb-Agajanian will field Gavin Miller in the No. 21AZ as the team aims to deliver a third different Knoxville winner. Coastal challengers entered for the weekend include R.J. Johnson, Ryan Bernal, Charles Davis Jr. and Steven Snyder Jr. The Corn Belt Clash ties a marquee USAC event to Hall of Fame festivities at a facility often called the “Sprint Car Capital of the World.” Past Hall of Famers who previously won USAC races at Knoxville include Gary Bettenhausen, Dick Tobias, Sammy Sessions, Tom Bigelow, Sheldon Kinser and Sammy Swindell.

R.J. Johnson, the two-time defending Avanti Windows & Doors USAC CRA Sprint Car champion, won the 30-lap “Salute to Indy” main at Perris Auto Speedway, prevailing in a 14-car field. Johnson started sixth in Petty Performance Racing’s No. 1P Sherman, carrying Avanti Windows & Doors and Apache Transport sponsorship, and used the low groove to work to the lead in a race that featured multiple lead changes and two distinct grooves.

Johnson held off a late charge from Tommy “Thunder” Malcolm, who charged from fifth in Dino Napier’s No. 5x Maxim and had been running the top groove, until Malcolm’s engine expired with five laps remaining. Brody Roa finished second, Eddie Tafoya Jr. was third, Cole Wakim fourth and Austin Williams fifth.

The victory was Johnson’s third of the season and the 14th of his career. He also picked up the Woodland Auto Display Fast Time Award with a lap of 16.677 seconds and earned a Best Passing Job recognition. The USAC CRA Sprint Car series is scheduled to return on June 6 to Santa Maria Speedway.

Briggs Danner passed Logan Seavey on lap 17 and won the USAC AMSOIL Sprint Car 40-lap Circle City Salute at Circle City Raceway, taking the $10,000 winner’s purse. Danner led the final 24 laps of the quarter-mile feature. Seavey had led the opening 16 laps and finished second, while Kyle Cummins set a new LearnLab qualifying track record at 11.601 seconds, started 10th and finished third.

Cummins retained the USAC national points lead at 1,058. Mitchel Moles was second with 970, Justin Grant third with 969, Logan Seavey fourth with 892 and Briggs Danner fifth with 871. Moles and Reinbold-Underwood Motorsports have four fast qualifying awards at Circle City Raceway; Moles had held the one-lap USAC track record at 11.819 seconds set in 2022 before Cummins’ new mark. Moles and Reinbold-Underwood recorded two runner-up finishes at the track in 2025 and were still pursuing their first CCR race win together.

C.J. Leary extended his streak to 328 consecutive USAC feature starts dating to 2017 and is a two-time Circle City Raceway winner (2022 and 2025). Jacob Denney, who earned his first sprint car feature victory at CCR in April, was making his first USAC National Sprint Car start for Team AZ/Curb-Agajanian at the Circle City Salute. Rookie Cale Coons was seeking his maiden USAC National Sprint Car series win. The weekend featured several flips, including Ricky Lewis in qualifying and Chet Williams and Todd Hobson in semis. The Circle City Salute has produced four different winners in as many runnings; the 2025 running was officially listed as a rainout and credited to Mother Nature.

Kyle Cummins won the 30-lap USAC AMSOIL National Sprint Car feature at Eldora Speedway in Rossburg, Ohio, in Friday night’s #LetsRaceTwo opener. He led 24 laps (6–28, 30), briefly ceded the lead to Justin Grant on the white flag, then regained it on the final lap to take the victory. Cummins earned the K&N Clean Air Award and a $12,000 winner’s payout.

It was his third USAC National Sprint Car feature win of the season and came in his 17th career Eldora USAC AMSOIL National Sprint Car feature start, driving the Petty Performance Racing entry (Avanti Windows & Doors/JUGO Superfoods/Mach-1/Stanton Chevy). The result moved Cummins to the top of the USAC national sprint car standings with 839 points, 60 points ahead of Justin Grant (779) and 76 points ahead of Mitchel Moles (763).

Brady Bacon finished second and Justin Grant third. Grant also led lap 29 and was the LearnLab fast qualifier with a lap of 15.875. Briggs Danner started on the pole and finished fourth, Chase Stockon led the opening five laps and finished fifth. Bacon posted the Dirt Draft Hot Laps fastest time at 16.178 and received contingency honors. Jakeb Boxell flipped on lap 27 and was classified 24th. The victory continued a strong run for Cummins at Eldora after his 2025 campaign, when he recorded a spring podium and two runner-up finishes in September.

USAC AMSOIL National Sprint Car teams will visit southern Indiana for a two-track weekend on May 1 and May 2. The 19th Larry Rice Classic is scheduled for Bloomington Speedway on Friday, May 1, and the 13th Spring Showdown will follow at Tri-State Speedway in Haubstadt on Saturday, May 2. General admission is $30 per night, and both events will be streamed live on FloRacing.

Kyle Cummins leads the USAC national standings and arrives as the defending dual-winner at Bloomington Speedway and Tri-State from 2025. He added a USAC victory at Terre Haute earlier this month and also won a dominant unsanctioned feature at Kokomo. Cummins has a run of seven straight USAC top-five finishes heading into the May weekend.

Primary challengers include C.J. Leary, driving the Fox Brothers/Brayden Fox Racing No. 53, the 2023 Larry Rice Classic winner who holds Bloomington’s one-lap record at 10.685 seconds, and Kevin Thomas Jr., who has 13 career USAC feature wins between Bloomington and Tri-State and who won the Spring Showdown in 2013, 2018 and 2024 and the Larry Rice Classic in 2021. Thomas has not recorded a USAC feature win in 2026 as of this preview. Four past Larry Rice Classic winners, Thomas Jr., Leary, Logan Seavey and Cummins, are entered for Friday’s program. Team Arizona/Curb-Agajanian will debut a part-time No. 21AZ entry at Bloomington driven by Gavin Miller and Jacob Denney, with Miller set to make his first USAC National Sprint Car start after strong Kokomo performances. Mitchel Moles has been a frequent fast qualifier at both Bloomington and Tri-State in recent seasons.

Two reports conflict on the winner and standings following the USAC NOS Energy Drink midget 30‑lap feature at Kokomo Speedway. One report credits Jacob Denney in the No. 67 Kunz/Curb‑Agajanian entry with the win and the other credits Justin Grant. The sources also differ on the event date, with one listing April 25 and the other April 26, and they disagree on qualifying results, heat winners and the points standings.

According to one account, Jacob Denney won the 30‑lap feature after taking the lead on lap 3 and leading to the finish. That report lists Gavin Miller second and Kevin Thomas Jr. third. It names Jakeb Boxell as the LearnLab fast qualifier with a 12.907 and lists the Dirt Draft hot‑lap leader at 13.138. Heat winners are listed as Kevin Thomas Jr., Jacob Denney and Justin Grant, and that account puts Denney atop the national championship standings with 150 points, Thomas at 149 and Justin Grant at 147.

An alternate account credits Justin Grant with the 30‑lap victory after he took the lead from Zach Wigal on lap 13. That version lists Wigal second and Denney rallying from 19th to third and earning the Rod End Supply Hard Charger award. It lists Kevin Thomas Jr. as the LearnLab fast qualifier with a 13.074 and the Dirt Draft hot‑lap leader at 13.154. Heat winners are named as Gunnar Setser, Jakeb Boxell and Ethan Mitchell, with Boxell also noted as a heat winner. That account records different season points: Grant 78, Wigal and Thomas tied at 74, and Denney 70.

Both reports describe a series of on‑track incidents, including qualifying flips involving Thomas Meseraull, Colton Robinson and Trevor Cline, heat‑race flips involving Tyler Watkins and Kyle Jones, and a flip by Drake Edwards in the feature on lap 18. Coverage did not indicate life‑threatening injuries from the qualifying, heat or feature incidents. The conflicting accounts may reflect different timing and tally updates, such as night totals versus an updated national tally. Verify the official finishing order, qualifying times, heat results, the correct event date and the points standings against USAC timing and results before publication, and confirm which tally each source used. The USAC midget series will pause and resume on June 9 at Circle City Raceway in Indianapolis.

Kale Drake has signed with RMS Racing to drive the team’s No. 4 car for the full 29-race USAC NOS Energy Drink Midget National Championship. The 20-year-old from Collinsville, Oklahoma, will relocate to RMS’s Cedar Lake, Indiana, shop to work full time with the team, and his season is scheduled to begin at the Kokomo Grand Prix on April 24-25.

The move marks a personnel shift in the USAC paddock as Drake leaves a high-profile development program to join a new race team. He arrives after more than two seasons with Keith Kunz/Curb-Agajanian Motorsports, carrying 46 USAC National Midget starts and three USAC feature wins over the past two seasons, including victories at Sweet Springs Motorsports Park and Circle City Raceway. Drake won the 2025 USAC Indiana Midget Week title, finished fifth in the 2025 USAC National Midget standings, and won a BC39 preliminary feature at Indianapolis in 2024. He also ran several events for RMS before signing, including a third-place finish at I-44 Speedway in Oklahoma City.

Discussions about the signing began late last year between Drake, RMS crew chief Lacey Doyle and owner Dave Estep. RMS brings 22 USAC National Midget feature wins and marquee victories, including Turkey Night, the BC39 and the Hangtown 100, and the team expects Drake to help extend that success.
