Marks, a native of Northern California, is looking forward to making his Cup Series debut at the NASCAR track closest to his hometown, Los Altos.
"It's really the culmination of a dream to be able to compete in the NASCAR Sprint Cup Series," explained Marks. "It's fitting that it's going to happen at Sonoma Raceway, where I kind of grew up racing and cut my teeth. I know Tommy and all the guys at TBR are going to bring a well-prepared GoPro Chevrolet to the track, so it's just going to be a matter of getting to know the Gen-6 car and getting reacquainted with the racetrack. My goal for the weekend is to run a clean, competitive race and keep that 7 car up in the points."
"We're really excited to have Justin in our car," said Tommy Baldwin, owner of Tommy Baldwin Racing. "He is a really great young man and with all his road course experience, I think he can definitely be successful in his Cup Series debut at Sonoma."
Marks will compete in the Toyota/Save Mart 350 at Sonoma Raceway on Sunday, June 23. The race can be viewed live on TNT, with coverage beginning at 3:00 p.m. EDT.
