(AP) Will Power won at Sonoma Raceway for the third time in four years Sunday, earning his first victory of the IndyCar season when he took advantage of a late penalty to 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 tire in the left hand of Power's tire holder while Dixon drove out of his pit directly behind Power's spot.
The tire holder went flying into another crew member, and a third member was injured by an air gun.
Dixon thinks Power's crew got in his way on purpose.
Dixon finished 15th and lost ground on overall IndyCar leader Helio Castroneves, who finished seventh.
Justin Wilson was second, and pole winner Dario Franchitti was third.
