Kyle Busch, Jimmie Johnson face stiff competition in Chase (The Associated Press)

Asked what drivers worry him as he seeks a second-straight Sprint Cup title, Kyle Busch identified Kyle Larson and Martin Truex Jr. ''It hurts to be outrun by somebody in your equipment,'' six-time champion Jimmie Johnson said. Of the 16 drivers to qualify for the season-ending Chase, half are from teams outside the behemoth organizations of Hendrick Motorsports, Joe Gibbs Racing and Team Penske.
