SEATTLE -- 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.
"I tell you what, that holeshot is so key," he said. "We made some great changes today on the bike. It was a tough track with so many lines, but there was one main line that was so much better than any other. I've been waiting for this since Phoenix."
Ryan Villopoto's runner-up finish extended his podium streak to nine races, during which he has finished either first or second.
"I didn't get the start I wanted, so to come out the way I did and salvage that was awesome," Villopoto said. "I rode 20 solid laps but Justin was on it. I just really couldn't do anything with him. The way it turned out tonight was pretty good for what we were up against (at the start)."
Davi Millsaps finished third for his 10th podium finish of the season, and moved into second in the championship standings. Villopoto holds a 25-point lead over Millsaps in the 450SX class standings and can clinch his third consecutive Monster Energy Supercross title if he maintains that advantage after next weekend's 16th race of the season.
In the first Western Regional 250SX class main event since February, Eli Tomac finished second behind Roczen, followed by Zach Osborne in third.
Roczen extended his lead in the point standings, having finished first or second in each of the seven races this season. He leads Tomac by 20 points with two races left.
"I just put my head down and rode smart," Roczen said. "The track was really technical out there, with a lot of ruts. It feels good to get a win after such a long break; it's tough to get in a groove after so much time off, but I'm so happy I was able to walk away with this one."
