Red Bull KTM’s Ryan Dungey has taken victory in Anaheim 2’s third round of the 2017 Monster Energy AMA Supercross series, taking over the points lead in the process.

Defending 450SX champion Dungey took advantage of clear air to claim his first win of the year by 2.725s from teammate Marvin Musquin and Cole Seely (Team Honda HRC).

However it was the injury – a suspected compound fracture of the forearm – for previous red plate-holder Ken Roczen (Team Honda HRC) and disqualification of Jason Anderson (Rockstar Energy Husqvarna) that made headlines tonight.

Dungey now holds a seven-point lead over Musquin in the standings, while Roczen is third and 18 points outside of the lead. His recovery period remains uncertain.

In the West Coast 250SX final it was Justin Hill (Monster Energy Pro Circuit Kawasaki) who won by over five seconds ahead of Aaron Plessinger (Star Racing Yamalube Yamaha) and title-leader Shane McElrath (TLD Red Bull KTM).

Of the Australian contingent, Chad Reed (Yamaha Factory Racing) rallied to seventh in the 450SX main event, as did Dan Reardon (Star Racing Yamalube Yamaha) in 250SX. Hayden Mellross (51FIFTY Energy Drink Yamaha) went out on the opening lap.
