Kyle Busch held off David Reutimann and Jimmie Johnson in a two-lap shootout to the finish to become the first Sprint Cup Series race winner at Kentucky Speedway.
Busch, the pole-sitter, dominated most of Saturday night's Quaker State 400 by leading 125 laps, but an accident involving Clint Bowyer in the closing laps set up the two-lap sprint to the finish. He finished 0.18 seconds ahead of Reutimann for his third Sprint Cup victory of the season and the 22nd of his career.
Reutimann passed Johnson to take second on the final lap, while Johnson settled for third. Ryan Newman and Carl Edwards rounded out the top-five.
Brad Keselowski led a total of 79 laps but faded in the closing stages to finish seventh.
With the win, Busch took a four-point lead over Edwards.
