Interstate Batteries High Limit Racing is staging the FS1-televised Speedway Motors Spring Jackpot at Eagle Raceway on Tuesday as a national television showcase of Roto-Rooter Midweek Series sprint car action. The Spring Jackpot is the second of six FS1 telecasts and the second of 16 Midweek Series rounds, and it is the first of two High Limit stops at Eagle this season. About 40 cars are entered for the midweek stop, which organizers say will sustain momentum ahead of the $50,000-to-win FK Rod Ends Eagle Nationals, which will return to Eagle Raceway on June 9.

The race carries championship implications: Tanner Thorson, driving the Rod Gross Motorsports No. 88, leads the Midweek Series by 27 points over Aaron Reutzel in the Ridge & Sons Racing No. 87. Pre-race favorites include Rico Abreu of Tony Stewart/Curb-Agajanian Racing, Giovanni Scelzi of Spire Motorsports, who has finished top 10 in all nine High Limit events and has an 11-race top-10 streak, Brad Sweet of Silva Motorsports and Reutzel. Kerry Madsen, the most recent Midweek Series winner and the defending Eagle Raceway winner, and Tyler Courtney, who won on the recent weekend at Tri-State Speedway, are also in the mix.

High-profile part-time entries expected include Corey Day (Jason Meyers Racing No. 14), Garet Williamson (Fischer Motorsports No. 23), Logan Seavey (CB Industries/Spire No. 87x) and Ryan Timms (Liebig Motorsports No. 10); speculation circulated that Kyle Larson was not expected to race. FloRacing will stream Hot Laps and Qualifying at 5:30 p.m. local (6:30 p.m. ET), and FS1 begins live coverage at 7:00 p.m. local (8:00 p.m. ET) to show Heat Races, a possible C-Main, the Dash, the B-Main and the A-Main. Sye Lynch and Tanner Holmes have each notched their first podiums of the season in recent rounds.

Kerry Madsen won the FK Rod Ends Dash to start on the pole and then led all 30 laps of the A-Main to win the Diamond Classic in the Interstate Batteries High Limit Sprint division at Lucas Oil Speedway in Wheatland, Missouri, Saturday night, holding off Sye Lynch and Tanner Holmes.

Sources differ on his age, one listing him as 55 and another as 54. He is a native of Australia based in Knoxville, Iowa.

The result was reported as Madsen’s first High Limit series win in his 30th start and the first High Limit victory for car owner Tony Vermeer, and it made him the second Australian to win in the series, after James McFadden. One report’s claim that the result was Madsen’s 25th visit to Whiskey Myers Victory Lane in the High Limit series conflicts with the characterization of the Diamond Classic as his first series win; that discrepancy remains unresolved in the available sources.

After the race Madsen moved to sixth in the High Limit standings, 78 points behind leader Tanner Thorson. The series will stop at Eagle Raceway for the Speedway Motors Spring Jackpot on April 21, and the Roto-Rooter Midweek Series will air live on FS1 at 8 p.m. CT.

Jonathan Davenport won The Gauntlet dirt late model feature at Davenport Speedway in Bulls Gap, leading all 60 laps of the 60-lap race. It was Davenport’s seventh win of the season, and promoter Vic Hill had posted a $100,000 bonus that boosted Davenport’s total take for four nights to more than $137,500.

Ricky Thornton Jr. finished second, Mike Marlar third, Cody Overton fourth and Chris Madden fifth. Organizers scheduled a Saturday finale that paid $30,000.

Chris Madden won the Friday-night 50-lap Gauntlet preliminary at Volunteer Speedway in Bulls Gap. Starting from the pole, Madden took the lead on lap 30 after Davenport suffered mechanical issues and fended off a late challenge from Zack Mitchell to earn $20,000. Some reports said Davenport’s Saturday victory “capped a sweep” of the weekend’s high-paying programs, and those accounts conflict with preliminary results showing Madden’s Friday $20,000 win.

Tanner Thorson of Minden, Nevada led every lap at Route 66 Motor Speedway in Amarillo to take a wire-to-wire victory in the Interstate Batteries High Limit Racing feature on Friday night. Piloting the Rod Gross Motorsports No. 88, Thorson notched his second win of the season and the fourth High Limit Racing victory of his career — all four coming since September — which returned him to Whiskey Myers Victory Lane and pushed his championship lead to 21 points after the eighth night of the 64-race season.

Aaron Reutzel of Clute, Texas, making his first start at the West Texas oval, closed to within 0.133 seconds on Lap 22 while the leaders navigated heavy lapped traffic and finished second for Ridge & Sons Racing, a team that has logged five podiums in the first eight races.

Justin Peck posted a season-best third, Daison Pursley was fourth in the Kasey Kahne Racing w/ Mike Curb No. 9, and Tanner Holmes recorded a season-best fifth in the Buch Motorsports No. 13. Rounding out the top 10 were Brent Marks, Hank Davis, Sam Hafertepe Jr., Kerry Madsen and Giovanni Scelzi.

Interstate Batteries High Limit Racing wrapped its nine-race season-opening swing this week with three races at first-time stops in New Mexico, Texas and Kansas. The swing concluded with the Roto-Rooter Midweek Series opener at Vado Speedway Park in Vado, N.M., on Tuesday, followed by Route 66 Motor Speedway in Amarillo, Texas, on Friday and Dodge City Raceway Park in Kansas on Saturday — each hosting its first-ever High Limit Racing events after weather had disrupted attempts to race there the previous year.

Tuesday’s Vado show aired live on FS1 at 7 p.m. local (9 p.m. ET), marking only the second live-television broadcast in series history and serving as the first of six FloSports/Fox simulcasts planned for the season; FloRacing exclusively streamed the Hot Laps and qualifying sessions ahead of the Vado race. Additional FS1 live dates have been scheduled at Eagle Raceway (April 21), Grandview Speedway (May 19), Red Cedar (June 3), Eldora Speedway (July 17) and Kokomo Speedway (Sept. 23).

The opening swing also highlighted strong on-track parity: the season produced six different winners in its first six races — Kyle Larson, Corey Day, Aaron Reutzel, Rico Abreu, Tanner Thorson and James McFadden — and early-season points leader Tanner Thorson recorded five straight top-five finishes and a recent victory. Defending champion Rico Abreu posted dash results of 7-7-3-1-3-10, while Giovanni Scelzi, working with crew chief Eric Prutzman, collected six top-10s without a win. Coming after earlier three-day weekends in Las Vegas and Phoenix, the nine-race swing wrapped the circuit’s opening set of races and positioned this week as a key moment for drivers, tracks, sponsors and fans as the series grows its visibility and competitive profile.

The Interstate Batteries High Limit Racing series continued to show striking early-season parity at the Cactus Classic at Central Arizona Raceway, producing a sixth different winner in the season’s first six High Limit shows.

Tanner Thorson won night two’s 25-lap feature after starting third, fending off an early challenge from defending champion Rico Abreu and catching Aaron Reutzel—who had led the opening seven laps—by lap 8. Thorson navigated heavy lapped traffic and a caution for James McFadden set up a green-white-checkered finish, which Thorson won. Reutzel finished second, and Abreu executed a last-lap pass on Tyler Courtney to take third. The victory was Thorson’s third career High Limit Racing win, making him the 11th driver to reach three career High Limit victories.

James McFadden captured the Cactus Classic finale in the Tarlton Racing No. 21 after starting from the outside pole and out-racing Giovanni Scelzi into turn one. A lap 11 red flag for Daison Pursley interrupted the event; McFadden briefly lost the lead on lap 12 but reclaimed it on lap 13. A lap 25 caution set up a five-lap sprint to the checkered flag, and McFadden held on to win by 0.511 seconds. It was McFadden’s fourth career High Limit victory and his first with Tarlton Racing — his previous three wins came with Roth Motorsports in 2024. Giovanni Scelzi posted a season-best second, while Brad Sweet rallied from 10th to third and collected the Rod End Supply Hard Charger honors.

Early in the Interstate Batteries High Limit Racing season, Central Arizona Raceway was expanded into a three-day Casa Grande special that paired High Limit’s Cactus Classic with NHRA’s Arizona Nationals. The weekend featured additional marquee drivers: six-time national champion Brad Sweet teamed with Paul Silva in Kevin Kozlowski’s W car, and USAC Triple Crown champion Logan Seavey made his High Limit debut in Chad Boat’s CB Industries No. 87, a separate entry from Aaron Reutzel’s Ridge & Sons Racing No. 87.

Rico Abreu won the Cactus Classic opener at Central Arizona Raceway, taking the lead on the final restart at Lap 14 and pulling away to a 2.697-second victory over Tanner Thorson, with Daison Pursley third. The win — Abreu’s first for Tony Stewart/Curb-Agajanian Racing and the 26th of his career — produced the fourth different winner in as many races this season.

After four of 64 races, Tanner Thorson leads the championship with 272 points and Rico Abreu is second with 263; Thorson’s runner-up finish extended his streak of top-five results. Earlier Las Vegas events produced wins for Kyle Larson, Corey Day and Aaron Reutzel; Reutzel (Ridge & Sons Racing No. 87) finished 10th, 2nd and 1st in the opening three races and briefly held the early points lead — two points ahead of Thorson and 16 ahead of Abreu, with Giovanni Scelzi and Tyler Courtney 24 points back. The Cactus Classic result shifted those early standings, underscoring how the expanded Arizona weekend and added entries have affected the early-season pecking order.

Central Arizona Raceway is expanding the Cactus Classic into a three-day Interstate Batteries High Limit Racing special running Thursday through Saturday, creating a doubleheader with the NHRA Arizona Nationals. The format pairs morning and afternoon drag racing at Firebird Motorsports Park in Chandler with evening sprint car programs in Casa Grande; the opening Cactus Classic will include crossover filming and appearances by visiting NHRA stars as organizers seek to emphasize fan engagement by stacking sprint car nights alongside the marquee NHRA weekend. Several NHRA names — including J.R. Todd, Ron Capps, Maddi Gordon and Matt Hagan — are slated to attend the opener.

On the NHRA side, the Mission #2Fast2Tasty Challenge returns to the NHRA Arizona Nationals at Firebird Motorsports Park as part of the 41st annual FMP NHRA Arizona Nationals presented by NGK Spark Plugs. The Saturday qualifying bonus event is in its fourth year and is run at 13 regular-season races; Josh Hart, the Top Fuel points leader, is seeking his first Mission #2Fast2Tasty victory in a rematch with Antron Brown, while rookie Maddi Gordon will make her Mission bonus-race debut against reigning world champion Doug Kalitta, who won the overall Mission title and five bonus races last year. Funny Car rematches include Chad Green versus Jordan Vandergriff, and past Phoenix winners J.R. Todd (2024) and Alexis DeJoria (2023) are scheduled to race each other. The Pro Stock entry list features Dallas Glenn, Greg Anderson, area native Matt Hartford and six-time world champion Erica Enders, who is paired with Greg Anderson, and the event is promoted as the “Duel in the Desert.” NHRA officials also said Arizona Nationals start times will shift earlier because of expected heat as NHRA marks its 75th anniversary season.

The High Limit series arrives with recent Las Vegas winners Kyle Larson, Corey Day and Aaron Reutzel; Reutzel’s 10th-2nd-1st sequence has put him atop the early-season High Limit standings in the No. 87 Ridge & Sons Racing entry, with Tanner Thorson two points behind and Rico Abreu, Giovanni Scelzi and Tyler Courtney following. The High Limit series lists fifteen full-time teams; ten of those teams have High Roller Club membership while five teams are jockeying for “Joker Fund” access with Kerry Madsen leading that chase. Notable driver moves include six-time champion Brad Sweet returning from retirement for a roughly 30–40 race part-time program with Paul Silva and Kevin Kozlowski after a February NARC 410 feature win, and Logan Seavey running roughly 15–20 winged events in Chad Boat’s CB Industries No. 87 in partnership with Spire Motorsports.
