STATESVILLE, N.C. — GMS Racing announced Wednesday that Manpower U.S. will sponsor 16-year-old Sam Mayer for his NASCAR Gander Outdoors Truck Series debut at Bristol (Tenn.) Motor Speedway on Aug. 15.

Mayer will also pilot the No. 21 ManpowerGroup Chevrolet Silverado at Martinsville (Va.) Speedway on Oct. 26 and ISM Raceway near Phoenix, Ariz., on Nov. 8.

ManpowerGroup®, the parent company of Manpower and headquartered in Milwaukee, Wis., is the leading global workforce solutions company which helps organizations transform in a fast-changing world of work by sourcing, assessing, developing and managing talent that enables them to succeed.


Mayer, from Franklin, Wis., is currently competing for the NASCAR K&N Pro Series East championship. In seven starts this season, he has two wins, six top-five and six top-10 finishes, two poles and has led 333 laps. He has also run six ARCA Racing Series events in 2019 earning five top-five finishes.


“I can’t believe I’m going to be making my first Truck Series start at Bristol next month, and I’m really excited ManpowerGroup will be on board with me for my three races this year,” Mayer said. “To have a worldwide company support me this early in my career is pretty incredible. I led every lap and won the K&N race at Bristol in April, so I’m hoping we can have a really solid performance for them in the truck race next month, as well as at Martinsville and Phoenix.”


“ManpowerGroup has called Milwaukee home for over 70 years and we’re passionate about helping people achieve their potential and develop in their career, so that’s why we’re excited to support Wisconsin native Sam Mayer in his career journey,” said Michael Stull, Vice President of Manpower North America
