California Speedway A Win For Kenseth

Tony Stewart's blown engine on lap 214 of the 250-lap event brought out a caution flag and sent the leaders to pit road for their final stop. A great pit stop by the crew of Matt Kenseth's No. 17 Roush Racing Ford got him out ahead of Biffle, but, until smoke began spouting out of the exhaust on Biffle's No. 16, Kenseth didn't expect to stay ahead.

"We made some adjustments on that last pit stop, that gave me confidence for the longer run, but Greg was pretty quick on a long run. When he was back there, I totally assumed he was going to run us down on a long run." Kenseth said.

Stewart led only 28 laps but overcame a botched pit stop and a flat tire to come from a lap down and challenge Biffle late in the race on California's 2-mile oval. But Stewart, who had been running at the finish in 30 consecutive races, saw his race come to an end in a puff of smoke.

That appeared to hand an easy victory to Biffle. But it wasn't to be.

Biffle led 168 of the first 218 laps and built margins up to 13 seconds before he lost a cylinder in his engine on lap 225.
