Finishing first is not out of the ordinary for NASCAR’S youngest champion in history, Sam Mayer. This season, the 17-year-old is setting another first.  For the first time in the sports’ history, nonprofit organizations will be showcased in custom, one-time only paint schemes on his No. 21 Chevrolet car this season. He is committed to using his platform to raise awareness for nonprofit organizations founded by professional NFL and NBA athletes and to being a role model for kids across the country – another Athlete Doing Good.
