At the 15th race of the 2012 Monster Energy AMA Supercross season, held in Seattle, Andrew Short captured his first career win in the 450 class.

Short, who's from Smithville, Texas, has been racing in the Supercross Class for nearly six years. He won in front of the more than 50,000 fans who filled Seattle's CenturyLink Field on Saturday night. Ken Roczen took second, followed by Jake Weimer in third.

"My team has been through some challenges, but we stuck together," Short said. "All I wanted to do was be out here and to win is unreal."

Washington's own Ryan Villopoto, who has clinched the overall title and has been on a winning streak this season, crashed in the first lap and was out of the race.

Ryan Dungey, who's missed the past five rounds because of a broken collarbone, returned to race in Seattle and took sixth place.

In the Western Regional Supercross Lites Class, Ryan Sipes got his first win of the season after taking a two-month break from the series because of injury.

"It just feels so good to come back form (my) injury like this," Sipes said.

Monster Energy Supercross continues next weekend in Salt Lake City, Utah.
