Two-night CMH Diamond Nationals this weekend at Lucas Oil Speedway

WHEATLAND, MO.—The stars of Dirt Late Model racing return to Lucas Oil Speedway this week for the 19th annual CMH Diamond Nationals Presented by Wieland and the mid-summer Lucas Oil Late Model Dirt Series event has been expanded to two nights.

Action is set for Friday and Saturday with winners of the Late Model features collecting $15,000 on Friday and $25,000 on Saturday. A red-hot championship battle between Ricky Thornton Jr. and Jonathan Davenport continues as Thonton holds a 20-point lead.

Davenport looks to close in at one of his favorite tracks. The 2024 Show-Me 100 winner is a four-time Diamond Nationals champ with eight feature wins at Lucas Oil Speedway since the spring of 2023. He finished second at the 2025 Show-Me 100 Presented by Missouri Division of Tourism.

Devin Moran and Hudson O'Neal are third and fourth in points, 260 and 320 points behind Thornton. O'Neal is a driver to watch at winning both nights of the Spring Nationals at Lucas Oil Speedway on April 11-12 and sweeping the preliminary features for the Show-Me 100 May 22-23 before finishing third in the Show-Me.

O'Neal is coming off a LOLMDS feature win on Saturday at Muskingum County Speedway in Ohio.

Along with the star-studded field of series regulars, a strong contingent of regional and local drivers will be on hand. Included is Payton Looney of Republic, the 2020 Show-Me 100 winner who's had a limited schedule in recent years. Looney announced on Monday that he would be driving a Captial Race Car owned by Jefferson City's Tucker Cox.

More than $145,000 in purse money will be up for grabs at the Diamond Nationals, which was canceled last year due to rain.

Friday's feature payout: 1. $15,000, 2. $7,000, 3. $5,000, 4. $4,000, 5. $3,000, 6. $2,500, 7. $2,400, 8. $2,300, 9. $2,200, 10. $2,100, 11. $2,000, 12. $1,800, 13. $1,600, 14. $1,500, 15. $1,400, 16. $1,300, 17. $1,200, 18. $1,100, 19. $1,000, 20. $1,000, 21. $1,000, 22. $1,000, 23. $1,000, 24. $1,000.
