Justin Barcia earned his 20th career 450SX Class podium with a runner-up finish. He is tied with Trey Canard and Tim Ferry for 33rd all-time on the list. He is looking for his 110th career start and 80th career top-10 in Arlington at Round 11. Jason Anderson rolled to his first podium of the season and 33rd of his career with a third-place finish. The result was good for his 85th top-10 and 95th start (89.5%).

Chase Sexton grabbed his first career top-five finish with a fourth. After missing six rounds, Sexton has reemerged with his first career top-10 finish (Daytona) and his first top-five finish (Arlington 10).
