Ricky Carmichael came out to play during the Atlanta Supercross parade lap - shame he didn't hang around to race...

The battle of the Ryans was white-hot as Dungey and Villopoto, tied for the series lead on points, ran 1-2 through the main - momentum, it seemed, was on the side of Villopoto who'd come from 20 points down in just a couple of weeks, and Dungey seemed frozen like a rabbit in the headlights.

But at Atlanta Dungey seemed back on form, and it was Villopoto who cracked first, coming up short in a rhythm section as they battled through the traffic. Incredibly, his exhaust filled with dirt and the unfortunate ginger ninja had to push his Monster Energy Kawasaki all the way back to the pits before he could rejoin, and then could only make 19th.

All of a sudden, momentum is back on Dungey's side, and his 20 point lead is back, now over Josh Hill. Hill, who's quietly having a pretty good season, crashed hard in practice but still managed to get good points with sixth - Trey Canard and Davi Millsaps took advantage of 'Poto's misfortune to take second and third on the night.

The MX2 class saw Pro Circuit's Dean Wilson take the holeshot ahead of Austin Stroupe, Christophe Pourcel and Justin Barcia. Wilson faded as the others made their way through, with Pourcel and Barcia seemingly as intent on colliding with each other as they were with racing.

Austin Stroupe fell whilst in the lead, collecting Barcia in the process, but an inspired Barcia remounted and began to run new leader Pourcel down before another crash dropped him right down the standings.

Pourcel took the win ahead of Stroupe and Brett Metcalfe to extend his lead at the top of the table.
