The NASCAR race held yesterday, August 8, 2025, at Watkins Glen International was won by Corey Heim in the NASCAR Truck Series.

For the NASCAR Cup Series, the most recent notable race winner reported is Chase Elliott, who won a race prior to this date but not yesterday specifically. No source lists a NASCAR Cup Series race taking place exactly "yesterday," August 8, 2025, so the latest confirmed race winner for that date is Corey Heim for the Truck Series event.

Corey Heim also leads the Truck Series standings with 6 wins this season as of August 8, 2025.
