The Astor Cup became his just 22 laps into the race on the Portland road course when O’Ward had an electronic issue on his Arrow McLaren Chevrolet and had to make an unplanned pit stop. He returned to the track down nine laps from the leaders.
Palou finished third, O’Ward finished 25th and Palou has the title cemented with two races remaining in the IndyCar season. Palou was feisty in the closing portion of the race and raced unnecessarily aggressive at times — even driving off course with four laps remaining and drag-racing Christian Lundgaard for position.
