BRISTOL, Tenn. -- As Jeff Burton considered how to beat Kyle Busch in the closing laps at Bristol Motor Speedway, he couldn't shake the lessons his mother taught him as a child.

"My mother always told me to do onto other people the way you want them to do you," Burton remembered. "That's the only thing I know to do. I've always tried to let the guy I am racing with set the rules. ... Kyle drives hard. He drives really hard. But he's always raced me with respect."

And with that, Burton refused to bump Busch out of the way yesterday, instead pulling alongside of him before Busch beat him in a drag race to the finish line to win the first Car of Tomorrow race.

The two have battled in the Busch Series this season, and had a stirring door-to-door duel in Las Vegas two weeks ago that Burton won as Busch spun backward across the finish line.

Burton credited Busch with racing clean that day, and both drivers had it fresh in their memories on the final three laps yesterday.

"Jeff Burton easily could have dumped me there in three and four, but I think our Vegas finish helped me out a little bit with that," Busch said. "I think I had some brownie points to use up."

Busch took the lead with 16 laps to go on a smooth pass around Denny Hamlin in thick traffic and stayed there through a pair of cautions. He had driven away from the competition when the 15th and final caution set up a three-lap overtime.

With Busch and teammate Jeff Gordon running 1-2 at the restart, the two plotted their own strategy with their respective crew chiefs.

"Well, good job guys," Busch sighed at the final caution. "We'll do what we can. I can't promise you anything."

"He'll be nice," crew chief Alan Gustafson said. "He'll play nice."

It didn't sound that way on Gordon's channel.

"Tell that 5, if I get a fender underneath him, he better think about the fact that we're teammates," Gordon said. "If I don't get a fender underneath him, I won't move him out of the way."

It never mattered, though, as Burton jumped past Gordon on the restart and quickly pulled onto Busch's rear bumper. Burton looked low and Busch threw a block, then he went high and Busch blocked that, too.

Burton finally pulled alongside Busch as they closed in on the finish line, but Busch nipped him at the flag for his first Nextel Cup victory on a short track.

Both drivers could have spun Busch to get past him, and the 21 year old appreciated the veterans for racing him clean.

"Without Jeff Gordon and Jeff Burton behind me, I never would have won this race," Busch said.

Gordon, the polesitter, wound up third and was thrilled with the effort after struggling for most of the race.

"That's an awesome win for him," Gordon said. "I wanted to race with him. I got a run on the inside and I knew Burton was going to get a run on the outside and I knew I was in trouble, so I just tried to hold onto third."

IRL

After six months of lamenting a championship lost, Dan Wheldon found the perfect antidote: a trip to his personal playground -- Homestead-Miami Speedway. He wasted no time taking the first step toward the IndyCar title, winning in dominating fashion in the season opener. Wheldon, last season's series runner-up, won for the third consecutive season here, outclassing the 20-car field Saturday. He led 179 of 200 laps in the XM Satellite Radio 300 and became the first driver in series history to win three consecutive events at the same track.
