Sprint Cup Series regulars swept the top four spots in qualifying for tonight's John R. Elliott HERO Campaign 300 Nationwide Series race at Kentucky Speedway.

Defending race winner Brad Keselowski earned his first pole in any series at Kentucky Speedway with a lap of 175.313 mph in the No. 22 Penske Racing Ford.

"Really happy to be this fast," he said.

Kyle Busch will start beside him on the front row after posting the second fastest lap (174.250 mph) in the No. 54 Joe Gibbs Racing Toyota as time expired in the final qualifying round.

Row 2 will feature two more moonlighting Sprint Cup drivers.

Paul Menard drove the No. 33 Richard Childress Racing Chevrolet to the third starting spot with a lap of 174.087 mph.

Defending Quaker State 400 winner Matt Kenseth will start fourth in the No. 20 Joe Gibbs Racing Toyota in his first career Nationwide Series start at Kentucky Speedway after qualifying with a lap of 173.745 mph.

The top Nationwide-only driver in qualifying was Brian Scott, who will start fifth in the No. 2 Richard Childress Racing Chevrolet. Chase Elliott will start sixth in the No. 9 JR Motorsports Chevrolet. Series points leader Regan Smith will start 14th in the No. 7 JR Motorsports Chevrolet.

Tonight's race is the second leg of the Quaker State race weekend tripleheader for Keselowski, who now has 16 career Nationwide poles. He will be seeking his 29th career victory in the series, third this season and third at Kentucky Speedway.

"This race always turns into a handling race," Keselowski said. "You have to stay up with the track and keep up with your car to be fast the whole race."

Busch's bid to sweep all three races that make up the race weekend is alive and well.

On Thursday, he won the Camping World Truck Series' UNOH 225. Busch won the Nationwide Series race at Kentucky Speedway in 2004.
