Barcia second as Webb rides to spirited third at the ninth round.
The points at the top of the 450SX standings have been levelled after Ken Roczen dominated Atlanta’s ninth round of Monster Energy Supercross.
The Team Honda HRC rider grabbed the hole-shot and never looked back as he went onto record a stunning 13.612s over Monster Energy Yamaha Factory Racing’s Justin Barcia, which now sees him share the points lead with Eli Tomac (Monster Energy Kawasaki).
There was chaos unfolding behind Roczen, as Tomac went down after an aggressive pass on Blake Baggett (Rocky Mountain ATV/MC KTM) in the early stages, while a pile up later in proceedings caught out Jason Anderson (Rockstar Energy Husqvarna Factory Racing), Vince Friese (Smarttop Bullfrog MCR Honda) and Dean Wilson (Rockstar Energy Husqvarna Factory Racing).
Martin Davalos (Team Tedder KTM) held a podium position until the final lap, where he was ultimately passed by reigning champion Cooper Webb (Red Bull KTM Factory Racing) and Tomac to finish in fifth.
Justin Hill claimed sixth (Smarttop Bullfrog MCR Honda) followed by Aaron Plessinger (Monster Energy Yamaha Factory Racing), Malcolm Stewart (Smarttop Bullfrog MCR Honda), Friese, and Wilson.
Monster Energy Supercross heads to Daytona, Florida, next weekend.
