The defending series champion was the leader when a four-car accident brought out the caution with six laps to go in the race. That set up a final two-lap overtime sprint, and Bowyer lined up next to Carl Edwards for the double-file restart.
With Kyle Busch pushing him from behind, Bowyer raced to the front. He didn't have to deal with a challenge from Busch because an accident in the fourth turn brought out a race-ending caution, giving Richard Childress Racing its first win of the year.
Busch was second, followed by Edwards, Joey Logano and Kasey Kahne.
