In a race that saw tire problems turn the contest upside-down, Kyle Busch won Sunday’s Auto Club 400 in a green-white-checkered-flag finish that took the fifth NASCAR Sprint Cup Series event of the year six laps past its scheduled distance.

The first driver on four fresh tires for a restart on Lap 205 at Auto Club Speedway, Busch passed Stewart-Haas Racing teammates Kurt Busch and Tony Stewart on the next-to-last lap, bringing rookie Kyle Larson with him.

Able to keep Larson behind him on the final lap, Busch crossed the finish line .214 seconds ahead of the 21-year-old, who had won the NASCAR Nationwide Series race at the two-mile track one day earlier.

The victory was Busch’s second straight and third overall at Fontana, his first of the season and the 29th of his career. Kurt Busch, who like Stewart took right-side tires only on the final pit stop on Lap 200, ran third, followed by polesitter Matt Kenseth and Stewart.

Jamie McMurray, Brian Vickers, AJ Allmendinger, Paul Menard and Carl Edwards completed the top 10.

“I knew four tires was going to win the race, so I’m glad (crew chief) Dave (Rogers) called that,” Busch said in Victory Lane. “There was some great racing up front between Tony and Kurt there. It was really interesting to watch that.

“I went into Turn 1 thinking I’m going to run the middle and then Tony started sliding off the bottom and I’m like, ‘Nope, not having it.’ I had to get some brake and cut my car to the left and drove underneath him and got him cleared off Turn 2, and I was able to keep Kyle Larson behind me.”

Though he ran second, Larson nevertheless earned Busch’s admiration in the process.

“Man, what a shoe that boy is,” Busch said. “If he would have gotten alongside of me, it would have been a whale of a race. I drove off into Turn 3, but I heard ‘Car inside’ on my left.

“If he drove it in further than I did, Jesus must have told him to stop… What an awesome race this track produced!”
