Nelson Piquet Jr. raced to his second NASCAR Trucks Series victory of the year Saturday night, passing Matt Crafton on the final lap at Las Vegas Motor Speedway. Piquet, the Brazilian whose father won three Formula One titles, also won at Road America in Wisconsin in June. Crafton took the lead on a restart after the final caution, with Piquet close behind. Piquet went to the bottom of the track on the final lap, and passed Crafton in the second turn.
