Growing up on a Watermelon Farm in Alva, Florida Ross Chastain knew from an early age he wanted to be a race car driver. The 22-year-old’s racing career began at the age of twelve, competing on local short tracks in both the late model and Fastruck Series events. His short-track career proved to be a success, scoring over fifty wins in feature events including the 2011 World Series of Asphalt at New Smyrna Speedway, winning three of eight events in the series.
Chastain made his NASCAR national touring series debut in the NASCAR Camping World Truck Series in 2011. Competing in only five events, Chastain prepared for a full season in the Truck Series in 2012. Driving for an under-funded, SS -Green Light Racing, Chastain finished seventh in just the second race of the season at Martinsville Speedway and capped off his rookie campaign with a career best third-place finish at Bristol Motor Speedway in August of that same year.
In January 2013, it was announced that Chastain would drive in 14 Truck Series events for Brad Keselowski Racing behind the wheel of the No. 19. Taking advantage of the opportunity, Chastain produced two poles, led 229 laps en route to four top-five finishes, including two second-place finishes, and seven top-10's, a break-out year for the Watermelon King.
In 2014, Chastain made his NASCAR debut at Charlotte Motor Speedway. Chastain raced in a total of seven Xfinity Series races in 2014, scoring a top 10 at Kentucky Speedway. For the 2015 & 2016 season, Chastain finished in the Top 20 in NASCAR Xfinity Series driver points. Since his Xfinity Series debut, he scored four top 10s and 37 top 20s. His best Xfinity Series finish to date is ninth at Daytona.
For the 2017 Xfinity Series Season, Ross will be returning to the No. 4 Chevy full-time.
