Ross Chastain moved to the No. 1 Trackhouse Racing Team Chevrolet full-time for the 2022 NASCAR Cup Series season and collected his first, and the organization's first, win at Circuit of The Americas. He followed that up four weeks later with a win at Talladega Superspeedway. In 2021, he drove the No. 42 for Chip Ganassi Racing before the team was sold. He previously drove the No. 10 Kaulig Racing machine in the 2020 Xfinity Series. In 2019, he shifted gears midseason to run for the NASCAR Camping World Truck Series championship with Niece Motorsports. Chastain's first Trucks win came at Kansas in May, followed by wins at World Wide Technology Raceway at Gateway and Pocono Raceway. He has also earned two Xfinity Series wins, at Las Vegas in 2018 and Daytona in 2019.
