Kyle Busch claimed his fourth Sprint Cup member field for the championship Chase by taking Sunday's Pure Michigan 400 at Michigan International Speedway.

Busch grabbed the lead from Jimmie Johnson with 12 laps remaining and then held off Johnson during a green-white-checkered finish for his 23rd career win in the series.

Johnson, the five-time defending series champion, finished second, marking his best run at this two-mile track.

Michigan-native Brad Keselowski took the third spot, while Mark Martin and Ryan Newman completed the top-five.

Greg Biffle, the pole sitter, dominated early by leading 86 laps, but Biffle faded in the second half of the race and wound up finishing 20th.

Just three races remain before the Chase begins on September 18 at Chicagoland Speedway.
