LAS VEGAS (AP) - Ross Chastain held off Justin Allgaier for his first NASCAR Xfinity Series victory Saturday, pulling away on the final restart.
Chastain led 180 of the 200 laps, but had to dig in on several restarts to stay in front of Allgaier, the regular-season Xfinity champion. Cole Custer was third, followed by Christopher Bell and Elliott Sadler.
Chastain swept all three stages at Las Vegas Motor Speedway, and Allgaier clinched the overall regular-season series title during the second stage.
Matt Tifft spun on the 64th lap and wrecked Ryan Reed, sending both cars hard into the wall. The race also had two significant wrecks in the final 20 laps, delaying the finish significantly.
