What won the race: Slipping by polesitter Billy Moyer Jr. on the opening set of turns, third-starting Eli Ross of Muskogee, Okla., repelled race-long pressure from Cade Dillard for a commanding flag-to-flag victory in Friday's 20-lap Hayden Ross Memorial prelim at his home track of Thunderbird Speedway. Ross beat Dillard by 1.168 seconds for the $6,916 victory, including $1,850 in lap leader bonus money, in the race tri-sanctioned among the Comp Cams Super Dirt Series, Nutrien Ag Solutions Revival Super Dirt Series and Ross Foundation Sooner Late Model Series.

Key notes: Ross earned his ninth overall feature victory of the season, his first this year at his home track. ... The win is his first on the Comp Cams circuit, his eighth on the Revival tour (his sixth of 2026) and 12th on the Sooner Series (fourth of '26). ... Ross also won last year's Sooner-sanctioned event that honored his older brother, Hayden Ross of Muskogee, Okla., who tragically died in October of 2022 at the age of 20 and was posthumously crowned the 2022 Sooner Series champion. ... He'll be seeking the weekend sweep in Saturday's identical $5,066-to-win program at Thunderbird. ... Points leader Cade Dillard pressured Ross on numerous occasions but nearly lost the runner-up spot to Kyle Beard, regaining it as they raced towards the white flag and dropping Beard to third. ... Tenth-starting Timothy Culp finished fourth after he briefly held third on a lap-14 restart. ... Teenager Tyler Kuykendall climbed six spots to place sixth. ... Clay Stuckey (lap 12) and Morgan Bagley (lap five) each overcame flat tires in finishing eighth and ninth, respectively. ... The race was slowed by six cautions, none bigger than a massive multicar pileup on a lap-five restart that necessitated a 25-minute red flag for cleanup. It was unclear what triggered the mess, but Dakota Dellinger was pushed upside down in a melee that eliminated seven starters, including Billy Moyer; all drivers were OK. ... R.C. Whitwell completed just one more lap before calling it a night. ... Kylan Garner retired from ninth a couple laps later. ... Sixth-running Tyler Wolff spun for the third stoppage on lap six before soldiering to an 11th-place finish. ... Polesitter Billy Moyer Jr. faded to 11th by lap 14 before slowing with a flat tire and pitting. ... Shawn Mann drew the final caution on lap 15. ... The 20-lapper lasted 49 minutes with 15 starters completing the distance. ... John Briggs scratched after heat race action and Ryan Johnson scratched after hot laps.

On the move: Brett Hansen of Fort Gibson, Okla., started 16th and finished seventh.
