Reigning champion Justin Allgaier withstood a challenge from Aric Almirola to win Saturday’s NASCAR Xfinity race at Las Vegas Motor Speedway.

Sammy Smith started on the pole for the first time in his five races at Las Vegas Motor Speedway, but Justin Allgaier quickly overtook him to win stage one. Aric Almirola pushed to the front during the second stage, and it became clear pit stop strategy and paying attention to the small details would come into play.
