Mechanical failure doomed Kyle Busch's No. 18 Toyota yet again Sunday at Kansas Speedway.
KANSAS CITY, Kan. -- Yogi Berra said, "It ain't over till it's over."
For Kyle Busch
, it's over.
Busch had a mechanical problem for the third consecutive race, finishing 28th in the No. 18 Toyota. The man who led the standings and dominated the regular season is now 311 points behind in 12th place, the Chase cellar.
His car had an engine problem Sunday that stumped the crew.
"It was just sputtering and not running clean," Busch said.
Crew chief Steve Addington said it was some type of fuel pressure issue.
"We were 25 laps into the race and thought the motor was doing what it did last week and coming apart," Addington said. "We came in, checked all the lines and couldn't find anything. We'll go back and dissect the whole car."
Busch was 208 points ahead of second-place Carl Edwards
before the Chase began. He was 30 points ahead when the standings were reset for the playoff.
Any realistic chance he had of getting back in contention has ended. Busch was asked afterward how he feels.
"I think it's pretty self-explanatory to everybody out there," Busch said.
The three Joe Gibbs Racing cars hold down the last three spots in the Chase. Tony Stewart
, who finished 40th Sunday, is 11th. Denny Hamlin
, who finished 11th at Kansas, is 10th in the playoff rankings.
"My teammates now are having the same luck I've had all year," Hamlin said. "We're all trying new stuff and trying to get better. We're just trying to keep our stuff together."
