LAS VEGAS -- Tyler Reddick stretched his final tank of fuel Saturday to win the NASCAR Xfinity Series race at Las Vegas Motor Speedway and wrap up the regular-season championship.
Christopher Bell had the most dominant car but Reddick's Richard Childress Racing team gambled on fuel strategy to beat Bell for the win. The reigning series champion has five wins this season.
Reddick had to save as much gas as possible over the final stretch and the conservation mode allowed Bell to close the gap. Bell and his Joe Gibbs Racing team were likely hoping Reddick ran out of gas, but he picked up his pace over the final four laps as Bell closed in.
