En route to winning his fourth Main Event of the year, GEICO Honda’s Eli Tomac clinched the first Western Regional Supercross Lites Class Championship of his career.

Rockstar Energy Racing Suzuki’s Jason Anderson, of Edgewood, N.M., won the Nuclear Cowboyz Holeshot Award with his teammate Martin Davalos, of Cairo, Ga., to start the Western Regional Supercross Lites Class. On the opening lap, Red Bull KTM’s Marvin Musquin, of Murrieta, Calif., moved into second, while Monster Energy/Pro Circuit/Kawasaki’s Dean Wilson, of Menifee, Calif., secured third place.

Wilson quickly passed Musquin while Tomac moved into third place. Tomac stalked Wilson for several laps before making the pass for second on Lap 8. It didn’t take long for Tomac to cut into Anderson’s lead and make the race-winning pass on lap 10. A dramatic turn of events happened on Lap 12 when Wilson, who came into tonight’s race four points behind Wilson, suffered a huge crash that forced him to withdraw from the race. As a result, Tomac scored enough points to clinch the championship. Anderson and Davalos earned career-best results, finishing second and third, respectively.

“It was huge to close out the night with a race win and a championship,” said Tomac. “That was some good racing out there. Off the gate I got bumped around and was able to slowly pick guys off and try to pace. I did my best not to do anything stupid. That was the best way to do it.”

The final race of the 2012 Monster Energy Supercross Championship takes place next Saturday, May 5 at Sam Boyd Stadium in Las Vegas.
