Sonoma, Calif. • 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 when Dixon left his pit directly behind Power's Team Penske Chevrolet.
The tire holder went flying into another crew member, and a third member was injured by an air gun. Dixon thought Power's crew got in his way on purpose, leaving him angry and confused by IndyCar's latest call against him.
"That's probably the most blatant thing I've seen in a long time," Dixon said. "You watch most pit guys, they try to get out of the way of other people, so that was a bit of a [classless] move, to be honest. ... If that's the way they want to try and win, that's pretty bad."
Dixon finished 15th and lost ground on overall IndyCar leader Helio Castroneves, who finished seventh.
Sebastian Vettel overtook Lewis Hamilton on the first lap and comfortably held his lead to win the Belgian Grand Prix in Spa, Belgium, and extend his overall championship lead. Fernando Alonso drove brilliantly from ninth on the grid to take second place ahead of Hamilton.
