Kyle Busch overpowered the field yesterday in the NASCAR Nationwide Race at Texas Motor Speedway, winning in the second-tier series for a record-tying 10th time this season.

Busch, whose first victory of the season came on the same 1.5-mile oval in April, matched Sam Ard's season record set in 1983. He held off a charging Carl Edwards in the final laps of the O'Reilly Challenge.

The strong run by Edwards, combined with Clint Bowyer's sixth-place finish, moved Edwards within 91 points of the series leader with two races remaining.

Although Busch has had a disappointing run in the Chase for the Sprint Cup and is out of contention for the title despite dominating the regular season, he has a total of 21 victories this season, including eight in Cup and three in trucks.

But this one was special as the 23-year-old Busch dedicated the latest win to South Carolinian Ard, a two-time Nationwide -- then called the Busch Series -- champion suffering from Alzheimer's disease and in tough straits financially.

"Sam Ard was one of the pioneers of the sport and this really means a lot to me," Busch said after his now-traditional victory bows to the crowd. "I got to thinking about it and I decided I'm going give him $100,000 to try to help him out."

Edwards, who won the Nationwide title a year ago, is second in both this series and Cup,

Edwards gave up some track position yesterday, falling from second to fifth when he took four fresh tires during a late pit stop, while Busch and Mark Martin, who finished third, took two. But Edwards quickly moved forward, taking second place from Martin on lap 196 and getting within three car lengths of the leader on the final lap.

Carl Edwards looks at the last three NASCAR Sprint Cup races of 2008 and sees nothing but opportunity.

Sure, the series runner-up trails leader Jimmie Johnson by a daunting 183 points. And with Johnson needing only to finish ninth or better in the remaining events to win his third consecutive Cup title, it probably isn't a good omen for Edwards that Johnson has finished ninth or better in each of the seven Chase for the championship races so far this year -- or that Johnson is the defending winner of Sunday's Dickies 500.

There is also the fact that the biggest comeback over the final three races since the current points system began in 1975 came in 1990 when Dale Earnhardt overcame a 49-point deficit.

Never mind the overwhelming odds. Edwards, coming off a win at Atlanta, likes to think it's Johnson who is under the gun heading into the race at Texas Motor Speedway.

"I'm sure there's pressure on him," Edwards said. "I've been in a couple of championship battles; the ones that I remember the most were the ones at my local dirt track and stuff. It wears on you and it's easier to come from behind, that's for sure."

Besides Edwards, the only drivers with a legitimate chance to catch Johnson are third-place Greg Biffle, 185 points behind, and fourth-place Jeff Burton, 218 points out of the lead.

Ron Hornaday Jr. won at Texas again, coming from a lap down early for a dominating NASCAR Truck Series victory Friday that got him within six points of points leader Johnny Benson with two races to go.

Hornaday, caught in the pit on an early stop because of a caution, regained the lead from Kyle Busch on lap 108 of the 147-lap race at the 1 1/2-mile high-banked Texas Motor Speedway Friday. Hornaday finished 0.958 seconds ahead of Busch, who led 87 laps in a backup truck salvaged this week from a hauler fire.

Benson finished third, nearly nine seconds behind. But by passing two trucks in the final five laps to get that close, Benson retained the points lead .

Lewis Hamilton, 23, will become the first black Formula One champion, as well as the youngest, today if he finishes fifth or better in the Brazilian Grand Prix, if pole-winner Felipe Massa finishes third or worse or under a handful of other scenarios in between.

"I have my people behind me, and all the pressure will be on [Hamilton], especially when you think about what happened at this race last year," said Massa, a Brazilian who can become the first non-European champion in more than a decade and the first from his country since Ayrton Senna in 1991.
