Duke started his Truck career at the age of eighteen, driving for SS-Green Light Racing at Martinsville Speedway. With funding from Merrill Lynch, he finished 34th of 36 trucks, 41 laps behind race winner Denny Hamlin.[1] Three weeks later, Duke was hired by Key Motorsports to drive the team's No. 40 car in the penultimate race of the 2011 season at Phoenix. He avoided multiple crashes to finish 23rd, and turned in another top-30 effort the following week at Homestead-Miami Speedway.[2]
A return to SS-Green Light was in store for 2012, as Duke ran the season-opening NextEra Energy Resources 250 but was swept up in one of the race's many crashes.[3] Although he didn't return to NASCAR that year, he continued racing, competing in the super late model division at Citrus County Speedway.[4]
