Kyle Busch won his fourth consecutive Nationwide Series race at the 1 1/2 -mile, high-banked track in Fort Worth on Saturday. The dominating victory came a day after he won his fifth trucks race in his last five starts in the series.

He will try to complete an unprecedented trifecta today and become the first driver to win all three of NASCAR's national series on the same weekend.

"I hope it happens, that would be the greatest thing," Busch said. "The hardest one is the last one."

Busch qualified fifth for today's race at Texas, where he is 0 for 9 in Sprint Cup races and finished 18th in April.

When Busch climbed out of the car in Victory Lane on Saturday, he said he was "sorry" he won and would make it three in a row. When asked later about what reaction he expected if he did pull it off, he said he was "messing with the fans" with his comment and wasn't sure.

"People would get tired of buying tickets to the Kyle Busch show, I guess," he said. "That's two, one more to go. . . . If luck is on our side and we play it smart, we could come out of here three for three. That would be pretty special."

After taking the lead on the 11th of 200 laps, when he swung his No. 18 Toyota around polesitter Matt Kenseth in the first turn, Busch went on to lead 179 laps and win by 3.154 seconds over Casey Mears, who was filling in for Jeff Burton in the No. 29 Chevrolet.

This is the 28th time in his career Busch has run all three series the same weekend. This is the seventh time this year and twice he won two races -- at Fontana in February and Bristol in August -- without being able to get the third. At Fontana, he won the Camping World Truck Series and the Nationwide races before finishing third in Sprint Cup.

"Maybe we can come up two spots better here," he said.

It was Busch's eighth Nationwide victory this year, and extended his points lead to 272 over Carl Edwards with two races left.

Busch, who has won 29 times in 171 Nationwide starts, has to finish only 15th next week at Phoenix to clinch his first NASCAR championship in any series.

Toyota talk

Toyota's withdrawal from the Formula One circuit will not affect the manufacturer's commitment to NASCAR, a company executive said. Lee White, president and general manager of Toyota Racing Development, said the operations are separate financially. "It should have no effect whatsoever on our NASCAR program and our NASCAR plan."--
