450SX red-plate holder Ken Roczen (Team Honda HRC) dominated the Triple Crown at Glendale’s fourth round of Monster Energy Supercross by securing the overall win with a trio of race victories.

Zach Osborne (Rockstar Energy Husqvarna Factory Racing) stormed to the hole-shot in main event one, leading Eli Tomac (Monster Energy Kawasaki) and Malcolm Stewart (Smartop Bullfrog Spas Motoconcepts Honda) in the early stages.

Points leader Ken Roczen (Team Honda HRC) made an incredible pass around the outside of Tomac in the sand section, going onto then pass Osborne – who crashed in the path of the German ace.

Roczen got through unscathed to secure the lead, fending off a bid from Tomac to secure victory. Tomac was second ahead of rookie teammate Adam Cianciarulo (Monster Energy Kawasaki), followed by Stewart and Jason Anderson (Rockstar Energy Husqvarna Factory Racing).

Sixth through to 10th was completed by Justin Barcia (Monster Energy Yamaha Factory Racing), Justin Brayton (Team Honda HRC), Cooper Webb (Red Bull KTM Factory Racing), Justin Hill (Smartop Bullfrog Spas Motoconcepts Honda) and Martin Davalos (Team Tedder Monster Energy).

Main event two was forced to be red-flagged after a nasty first crash involving Osborne and Justin Bogle (Rocky Mountain ATV/MC KTM), the latter being assisted off the circuit with the Alpinestars Medical Unit.

On the restart it was Roczen who shot out to the lead with reigning champion Webb in tow, but that was the last they saw of Roczen as he charged to a commanding win.

Webb struggled to maintain his position at the front, first being passed by Cianciarulo, who went down a lap later, then losing spots to Tomac, Anderson and Baggett – the trio finishing in that order with Webb in fifth.

Cianciarulo rebounded to cross the line sixth, followed by Brayton, Barcia, Plessinger and Dean Wilson (Rockstar Energy Husqvarna Factory Racing).

Another red-flag was thrown in the opening stages of main event three, which came due to nasty crash for Chris Blose (Chaparral FXR Racing Honda) in the whoop section.

Roczen benefited from the restart for the second time, securing the hole-shot and storming away from the field to a dominant victory.

Tomac went down on the early lap, but able to rebound, while his teammate Cianciarulo crashed heavily in the whoops during the final moments.

At the chequered flag, Anderson was second over Tomac, Webb and Davalos. The top 10 was made up of Stewart, Barcia, Plessinger, Brayton and Hill.

Roczen boosted his points by taking the overall, joined on the podium by Tomac and Anderson. Monster Energy Supercross now heads to Oakland in California for round five of the championship.
