SOUTHWICK, Mass. -- Australia's Brett Metcalfe raced to his first 450 Class victory Saturday in the AMA Pro Motocross series' rainy Southwick National, finishing third in the first moto and second in the second.

The Rockstar/Makita Suzuki rider edged Ryan Villopoto, the Kawasaki star from Poulsbo, Wash., who had 2-4 moto finishes. Suzuki's Ryan Dungey, from Belle Plaine, Minn., was third -- finishing 1-7. Villopoto leads the season standings after 10 of 12 races, eight points ahead of Dungey.

"I'm a winner now," Metcalfe said. "This career has been a roller coaster. After everything I've been through, to finally get a win after eight years just feels good.

"The first moto was the worst I've ever rode at Southwick, but I still got third. We prepared my bike for the mud in the second moto and it rode like butter. It was perfect. I knew I had to beat Villopoto for the overall. I saw him ahead of me, dug deep, and passed him."

Honda's Justin Barcia, from Monroe, N.Y., won the second moto after finishing 36th in the first. He ended up seventh overall.

Earlier, South Africa's Tyla Rattray rode to his fourth 250 Class win of the summer, and Ashley Fiolek, from St. Augustine, Fla., raced to her third Motorcycle-Superstore.com Women's Motocross Championship victory.
