SEATTLE (AP) -- Justin Barcia led from the start and got his second career 450SX class win as AMA Supercross returned to the West Coast for the 15th race of the season Saturday night.
Ken Roczen won his third 250SX class race in four events in the Western Regional Championship's return to competition.
Barcia led all 20 laps of the main event, mirroring the performance from his inaugural 450SX class victory at the second race of the season in Phoenix.
Series points leader Ryan Villopoto's runner-up finish extended his podium streak to nine races, during which he has finished either first or second. Davi Millsaps finished third for his 10th podium finish of the season, and moved into second in the championship standings -- 25 points behind Villopoto.
In the first Western Regional 250SX class main event since February, Eli Tomac finished second.
