Kyle Busch leads the NASCAR Auto Club 400 after 300 miles
The second caution of the day came on lap 104 when there was debris on the track, likely from the tire of David Gilliland. They went back to green on lap 108 with Kyle Busch still in front. He's been impressive on the two restarts.
Denny Hamlin pulled his car behind the wall on the 106th lap and within 15 more laps his crew started to disassemble their pit, meaning he was done for the day. The exact problem hadn't been determined, but Hamlin was blaming it on the engine.
The third 100 miles just seemed to drag along without a lot of change. Around lap 139 the green-flag pit stops started. Kyle Busch was among the first to come in, handing over the lead to Tony Stewart for a brief period. Kyle Busch regained the lead on the next lap.
At the conclusion of 300 miles, little had changed at the front. Kyle Busch was the leader followed by Stewart, Kevin Harvick, Jimmie Johnson, Brian Vickers, Ryan Newman, Matt Kenseth, Clint Bowyer, Paul Menard and Greg Biffle. Kyle Busch was leading by 4.697 seconds.
It seems that unless Kyle Busch runs into some kind of trouble he's going to be very difficult to beat.
