Denny Hamlin ducked under Matt Crafton with five laps to go and won the NASCAR Truck Series race at Martinsville Speedway on a day when the points lead was significantly jumbled with three races remaining. The victory Saturday was Hamlin's second in the series, both on NASCAR's oldest track. It came after he missed the drivers' meeting because it conflicted with the final minutes of Sprint Cup practice, and had to start at the rear of the field.
