Kyle Busch, of the Doosan Infracore Toyota team, celebrates after winning the Corona Mexico 200. Busch won his third consecutive Nationwide Series race on Sunday in Mexico City.

Mexico City ? Kyle Busch won his third consecutive race on NASCAR’s Nationwide Series, holding off Marcos Ambrose by less than a second Sunday in the Corona Mexico 200.

Busch passed Scott Pruett on the 72nd of 80 laps to take the lead. Pruett finished third, followed by Carl Edwards.

There isn’t a driver out there on a better run than Busch, who is second in the Sprint Cup standings and entered this race in third on the Nationwide list. He’s also leading the Truck Series standings.

This was Busch’s 27th career victory in NASCAR’s top three series – but first on a road course.

In a race that included two red flags, he stayed out of trouble on the 2.518-mile course at Autodromo Hermanos Rodriguez before finally moving past Pruett. Busch is not currently scheduled for a full Nationwide schedule, but with all these wins, how can he resist a run at the championship?

“The consideration is there, but still, it’s a race-by-race deal,” Busch said. “We’ll make a decision here shortly. I love winning. I’ll run as long as I can win. That doesn’t bother me a bit.”

Ambrose trailed by 1.139 seconds with two laps to go and cut over three-tenths of a second off that deficit on lap 79. But Busch was able to hold on for a 0.737-second win.

In 2007 at this race, Pruett was in a similar spot when teammate Juan Pablo Montoya sent him spinning. This year – at almost the exact same point in the race – it slipped away again.

“Our tires were just a little too used up at the end,” he said.

The third-place finish was still a career best for the 48-year-old Pruett, a road-course ace making his 10th Nationwide start. He finished fifth in Mexico City last year.
