Australian driver Will Power won at Sonoma Raceway for the third time in four years Sunday, earning his first victory of the IndyCar season.

He stole victory after taking advantage of a late penalty to New Zealand’s Scott Dixon for injuring three members of Power’s pit crew.

Dixon led until he received a drive-through penalty with 15 laps to go for clipping a tyre in the left hand of Power’s tyre holder while he drove out of his pit directly behind Power’s spot.

The tyre holder went flying into another crew member, and a third member was injured by an air gun.

Dixon, who finished 15th, thinks Power’s crew got in his way on purpose.

Justin Wilson was second, and pole winner Dario Franchitti was third.
