FAST FACTS: Dale Earnhardt Jr. won at Michigan in June to end a 143-race winless streak dating to his June 2008 victory at the track. … Johnson leads the season standings with four races left in the regular season. He has a one-point lead over Greg Biffle, and two-point advantage over Matt Kenseth. The top 10 will earn spots in the 12-driver Chase. Kasey Kahne, with two victories, holds the first of the two wild-card spots that will go to the drivers with the most victories in the 11th-20th spots. Kahne is 11th. No. 13 Ryan Newman, No. 14 Busch, No. 15 Jeff Gordon, No. 17 Ambrose and No. 18 Joey Logano each have one victory. Johnson, No. 5 Keselowski and No. 8 Tony Stewart lead the series with three victories. Each victory is worth three points when the points are reset for the 10-race Chase.
