Brad Keselowsi heads into Sunday's opening Chase race with a little extra confidence after dominating Saturday's Dollar General 300 at Chicagoland Speedway.

Keselowski led 158 of the 200-lap event and crossed the finish line 8.568 seconds ahead of runnerup Carl Edwards.

"It’s a great booster to get a win before going into the Chase," said Keselowski. "Our Dodges are fast."

Polesitter Brian Scott finished third followed by Aric Almirola and Sam Hornish, Jr.

Ricky Stenhouse, Jr. leads Elliott Sadler by 14 points with six races remaining in the 2011 Nationwide Series championship battle.
