BILLINGS, MT (Aug. 19, 2025) — The American Sprint Car Series (ASCS) begins its annual outing in “Big Sky Country” this Friday–Saturday, Aug. 22–23, at Big Sky Speedway in Billings, MT, for the annual running of the Harvey Ostermiller Memorial.
Big Sky Speedway has been a home to multiple races nearly every season since 2013 with the ASCS Frontier Region, helping foster a region of dedicated and competitive 360 Sprint Car racers. This weekend, those drivers will meet the national Series stars for the eighth time in history at the 3/8-mile oval, racing for a $4,000 check on Friday before the $15,000-to-win finale on Saturday.
The event is run in memory of local Montana racer Harvey Ostermiller, who was killed in a 2016 car accident at the age of 70. Outside of his 40-plus-year career in the seat, the Billings native was noted for his role in constructing Big Sky Speedway, which opened in 2003 and is now owned and operated by promoter Jerry Brey.
Tickets for both nights of the event are on sale now at the link below and will also be sold at the track on race day. If you can’t be there to watch in person, stream every lap live on DIRTVision.
FRIDAY + SATURDAY TICKETS
Here are the drivers to watch for and storylines to follow this weekend:
KING OF THE FRONTIER — When the northernmost regional subdivisions of the American Sprint Car Series go racing, one driver stands above the rest.
Canadian Sprint Car standout Kelly Miller is the two-time and defending ASCS Frontier Region champion. The 34-year-old Lethbridge, AB-native won both the Frontier and the Northern Plains Region championships last year with six wins in Frontier competition. He currently leads the Frontier Region points standings with five Feature wins and nine top-five finishes in the first 10 races, aiming for an unprecedented third-straight points championship with eight races left on the schedule.
Historically, Miller has been one of the most successful Sprint Car racers at Big Sky with 10 career Feature wins at the track, including three this year with the Frontier Region. In last year’s running of the Ostermiller Memorial, Miller was the highest-finishing ASCS regional driver, driving from 16th on the starting grid to finish seventh in the main event.
BIG SKY BIG DOG — For the past two years, the Ostermiller Memorial has been ruled by regional 360 Sprint Car racer Jake Bubak.
The 30-year-old from Arveda, CO, topped the 2023 edition of the event, which was sanctioned only by the ASCS Frontier Region. When the national ASCS stars invaded one year ago, Bubak stood up against the tall competition again, leading all 30 laps to pocket the $12,012 check and secure his fifth career national Series victory.
Bubak has been competitive with the Series this year, making three starts outside of Knoxville and posting three top-10 finishes — one of which came as a runner-up effort at WaKeeney Speedway last Friday, which was later vacated after coming up light at the scales.
TALK OF THE TOWN — Two weeks following his victory in the sport’s biggest crown jewel event, Ryan Timms is headed for Big Sky Speedway this weekend with Liebig Motorsports.
Timms, 18, of Oklahoma City, OK, led the 64th running of the NOS Energy Drink Knoxville Nationals presented by Casey’s flag-to-flag for the biggest win of his career last Saturday at Knoxville Raceway, topping the world’s best 410 Sprint Car drivers to claim the $195,000 grand prize. After backing that up with another win in weekly competition at Huset’s Speedway one week later, Timms and car owner Shane Liebig have hooked the Hampel Oil No. 10 up with a 360 engine and will make the tow to Billings to compete for the $15,000 grand prize.
Outside of the ASCS-sanctioned 360 Knoxville Nationals, Timms has not made an appearance with the national Series since sweeping the Winged Sprint Car portion of the 2023 Hockett/McMillin Memorial at Lucas Oil Speedway, nor has he ever competed at Big Sky in any form.
THE CHAMP RETURNS — For the first time since June, Seth Bergman is projected to join the American Sprint Car Series roster this weekend at a place he’s had success at before.
Bergman, the reigning Series champion from Snohomish, WA, has three career victories in ASCS competition at Big Sky, including a sweep of a two-day ASCS Frontier Region event in 2020, and the preliminary night of the Ostermiller Memorial last August with the national Series.
This weekend, he’s projected to be racing Big Sky with the national Series for the first time since Batesville Motor Speedway in June. Diverting from the national Series schedule shortly after, Bergman spent some time racing back around his native Washington, making four appearances at Skagit Speedway and recording two podium finishes — one with a 410 engine in the car — three top-fives and a seventh place in the marquee Fred Brownfield 360 Nationals event.
