Roush Racing's Greg Biffle needed overtime to win the NASCAR Nextel Cup race in Darlington, South Carolina.
He fell behind after a late pit stop but the caution flag came out five laps from the end when Mark Martin span.
Ryan Newman, who had taken charge late in the race, stayed on the track while Biffle pitted for tyres.
When the green flag was waved for a two-lap shootout, Biffle sped to the front to push Jeff Gordon and Kasey Kahne into second and third places.
