LAS VEGAS -- Ryan Dungey raced to his fourth victory of the AMA Supercross season Saturday night, holding off Davi Millsaps in the finale at Sam Boyd Stadium.
Dungey, the KTM rider from Belle Plaine, Minn., won the final two races of the season. He returned to action three weeks ago in Seattle after missing five races because of a broken collarbone.
"After the heat race, we made a change to the bike that really helped out in the main event," said Dungey, who took the lead on the first lap. "The track was hard-packed tonight and a little tough. I am really happy that I could get this win for the KTM team."
Ryan Villopoto won the season title. A nine-time winner this year, the Kawasaki star from Poulsbo, Wash., missed the final two races after injuring his left knee in a first-lap crash in Seattle.
Millsaps, a Yamaha rider from Murrieta, Calif., was second in the season standings, and Dungey finished third.
Honda's Justin Barcia, from Ochlocknee, Ga., won the Eastern Regional Supercross Lites finale, capping his championship season with his sixth victory.
"I am happy to close out the season with a win," Barcia said. "The track was difficult for me out there, but I was able to keep it together."
Teammate Eli Tomac of Cortez, Colo., led all 15 laps in the Western Regional Supercross Lites race for his fifth victory of the season.
"This shows that GEICO Honda has done a great job this year with us winning both Supercross Lites class titles and Wil (Hahn) finishing third," Tomac said.
Barcia then held off Tomac in the Dave Coombs Sr. East/West Shootout.
