Ryan Dungey, Alex Martin score victories at Glen Helen National

SAN BERNARDINO, Calif. -- Ryan Dungey won the Glen Helen National on Sunday for his first Lucas Oil Pro Motocross 450MX Class victory of the season and 39th overall.

Dungey, a Red Bull KTM factory rider from Minnesota, won the first moto and finished second in the second. A three-time season champion, he is coming off his third AMA Supercross season title and second in a row.

"The day was pretty good overall," Dungey said. "It's always positive in the grand scheme of things in the championship to gain ground and get an overall [win]."

Suzuki's Ken Roczen was second after sweeping the motos last week in Sacramento in the season-opening Hangtown Motocross Classic. Roczen won the second moto, and suspension problems relegated him to fourth in the first. He leads the season standings, two points ahead of Dungey.

"In my heart, I went 1-1 and that's all that matters to me," Roczen said. "There's nothing I can do about (a bike issue). The air just went out of my forks and I didn't feel safe doing some of the jumps."

Kawasaki's Eli Tomac was third, finishing third in each moto.

Alex Martin raced to his first 250MX Class victory, finishing second in each moto. The Yamalube/Star Racing Yamaha rider took the points lead.

"I'm so happy right now, this is just so surreal," Alex Martin said. "I haven't really had two motos that have been that solid. I made some big, big changes after we went on the West Coast break in Supercross, training-wise, and I think it's really paying off. I'm so stoked right now."

Jeremy Martin was second in the first 1-2 brother sweep in series history. He was fourth in the first moto and won the second. Cooper Webb was third to complete the Star Yamaha sweep, winning the first moto and finishing fourth in the second.

Kawasaki's Joey Savatgy, coming off a moto sweep in the opener at Hangtown, was seventh overall. He was ninth in the first moto and seventh in the second.
