Eleven cars set times before rain set in and cancelled qualifying, so the field was set by the rule book with points leaderKyle Busch on pole,Jeff Burton second andDale Earnhardt Jr. third.Jason Leffler (#70) andTony Raines (#34) did not start because qualifying was cancelled due to rain.Kenny Wallace and the #87 car, and the #08 car, without a driver, were both withdrawn earlier in the week.

In a mixture of luck, fuel economy and strategy,Dale Earnhardt Jr. scored his first win in 76 points races thanks to a late caution due toSam Hornish Jr.'s late-race crash, and agreen-white-checker finish withPatrick Carpentier andMichael Waltrip crashing near the start/finish line to end the race. Instead of completing a victory lap, or doing the traditional burnout, Earnhardt coasted on to pit road after he had run out of fuel.
