March 07--REPORTING FROM LAS VEGAS -- Austin Dillon held off a charging Ryan Blaney to win Saturday's race in NASCAR's second-level Xfinity Series.
Dillon, who mainly competes in NASCAR's premier Sprint Cup Series, had the dominant car Saturday at Las Vegas Motor Speedway, leading 183 of the 200 laps in the Boyd Gaming 300.
But on a restart with six laps left, Blaney -- who had taken fresh tires during a caution period -- closed the gap with Dillon's No. 33 Chevrolet and was on Dillon's bumper with two laps left.
Blaney then tried to take the lead in his No. 22 Ford, but Dillon blocked him to secure the win. Blaney nearly lost control twice as he tried to find a way around Dillon.
"It was a heck of a last two laps, that's for sure," Dillon said in Victory Lane. "The 22 put on a heck of a charge."
Blaney said Dillon "did what he had to do and stopped my run. I couldn't get to his outside [for the pass]."
Regan Smith finished third and Denny Hamlin, driving the No. 54 Toyota for the injured Kyle Busch, finished fourth.
