Regan Smith (#01) crossed the finish line first, but received a penalty for improving his position by passing Tony Stewart below the yellow line. The penalty for that is a pass-through, so he was moved back to the last car on the lead lap or the tail end of the longest line (18th position).
In a green-white-checkered-flag finish that took the race two laps beyond its scheduled distance of 188, Stewart was declared the winner, even though Smith crossed the finish line first. With a quarter-mile to go and Stewart protecting the bottom of the track, Smith was forced to dip below the yellow line, which divides the speedway proper from the apron, to complete the final pass for the lead In NASCAR's view, Smith's move was out of bounds, violating NASCAR's rule against improving position by passing below the yellow line. Accordingly, Stewart was awarded the victory, and Smith was demoted to an 18th-place finish as the last car on the lead lap.
