SONOMA, Calif. — Martin Truex Jr. won the NASCAR Cup Series race in Sonoma on Sunday, using a clever pit strategy to cruise to his second career victory on the challenging road course. Truex easily held off Kevin Harvick for his second win in three weeks and his third victory of the season in his Furniture Row Racing Toyota. The defending Cup Series champion waited to pit until the 81st lap, a full eight laps later than Harvick.
