Kyle Busch leads halfway through NASCAR Sprint Cup race in Fontana

Kyle Busch led at the halfway point of the NASCAR Sprint Cup Series race Sunday at Auto Club Speedway in Fontana.

Busch, who won the Nationwide Series race on the same track a day earlier, was just ahead of teammate Denny Hamlin in the Auto Club 400.

Joey Logano was third, Dale Earnhardt Jr. was running fourth and Matt Kenseth, a three-time winner at Auto Club Speedway, was fifth.

Brad Keselowski had climbed to 13th in his No. 2 Ford after the reigning Sprint Cup champion was forced to start at the rear of the 43-car field because of an engine change.

But near the halfway point of the 200-lap race, Keselowski was penalized for entering the pits too quickly and fell back to 26th.

Five-time Sprint Cup champion Jimmie Johnson was running 19th. Johnson is the only five-time winner at the two-mile Auto Club Speedway.

Danica Patrick, who started 40th, was running 34th.
