Kevin Harvick had won the last two NASCAR races in the Sprint Cup Series but Brad Keselowski broke through to win the Auto Club 400 at Fontana, California. Harvick was not far behind, however, in second place. Keselowski had to use a late pit stop to take four new tires while the other contenders took only two – the extra-tire gamble paid off as Keselowski came up with the checkered flag in the end. Harvick finished second and Kurt Busch finished third.
Harvick continues to lead the Sprint Cup Series with 225 points while Daytona 500 winner Joey Logano is second with 197 points and Martin Truex, Jr. is third with 192 points.
