What won the race: Polesitter Justin Wells of Aurora, Mo., scored his third career victory on the MARS DIRTcar Series, topping fifth-starting Tony Jackson Jr. of Lebanon, Mo., for a $2,000 payday at Flint Creek Speedway. Wells led all 30 laps.

Key notes: Prior to Friday, Wells's most recent MARS triumph came on July 17, 2011, at Monett (Mo.) Speedway. ... The Oklahoma oval was formerly known as West Siloam Speedway. ... The series made the first of two visits to Flint Creek. ... The tour's next Flint Creek visit is July 31, also in conjunction with a trip to Caney Valley Speedway in Caney, Kan., which hosts Saturday's MARS race.

On the move: Jackson climbed from fifth to notch runner-up honors.

Winner's sponsors: Wells's No. 98 is sponsored by Bill Vance Marine, B&P Discount Grocery, Doty Trash Service, Freedom Bank, Genesis Racing Shocks, Midwest Sheet Metal and U.S. Tool & Machining.
