Pole-sitter Kyle Busch dominated from start to finish, leading 195 of 200 laps en route to winning the NASCAR Nationwide Series Dollar General 300 at Chicagoland Speedway on Saturday.
Busch faced few serious threats, building his lead to seven-plus seconds to earn his 10th win in 20 Nationwide Series starts this season.
It was Busch's 61st career win in 264 career Nationwide starts, and his 123rd overall win across all three of NASCAR's top series.
Busch also won Friday's Camping World Truck Series race and goes for a second career weekend sweep in Sunday's opener of the 10-race Chase for the Sprint Cup championship playoffs. Busch previously won races in all three series on the same weekend at Bristol in August 2010.
Joey Logano finished second, followed by Nationwide Series points leader Sam Hornish Jr., Austin Dillon and Dale Earnhardt Jr.
