Kyle Busch raced to his sixth victory in his past seven Nationwide starts and ninth of the season Saturday night, leading 209 of 250 laps in a dominating run at Iowa Speedway.
Busch moved a victory away from the series season victory record of 10 he shares with Sam Ard. Busch, a 10-time winner in 2008, is second in series history with 39 victories - nine behind Mark Martin's record.
Kevin Harvick was second, followed by Jason Leffler and Brad Keselowski in front of a standing-room only crowd of roughly 55,000.
Trevor Bayne, who became the first Nationwide driver in 18 years to capture three consecutive poles earlier Saturday, finished fifth.
Harvick took the lead from Busch during a late pit stop by taking just two tires while Busch grabbed four. But Busch had the strongest car of the night, and he proved it by zipping past Harvick on the outside with 25 laps to go on the 0.875-mile oval.
For the second week in a row, Busch won without running a single practice lap.
TRUCKS: Elliott Sadler held off Kasey Kahne in a green-white-checkered finish to win the inaugural NASCAR Truck Series race at Pocono.
Sadler was the beneficiary after a flurry of late mishaps sent the trucks race into NASCAR's version of overtime. He cut off Matt Crafton's pass attempt inside, then pulled away from Kahne on the final lap to take victory.
It was Sadler's first trucks win, giving him victories in all three NASCAR racing series.
