PORTLAND, Oregon (AP) — Alex Palou has secured his fourth IndyCar championship in five seasons. On Sunday, at Portland International Raceway, title contender Pato O’Ward lost power early in the race.

O’Ward started from pole position and was the only driver who could have beaten Palou for the championship. Palou entered the race with a 121-point lead and clinched the title when O’Ward faced an electronic issue. Palou has won all his championships with Chip Ganassi Racing, dominating this season with eight wins and five poles.

He joins a select group of drivers with three consecutive titles.

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.

“We’re here to win. That’s why we’re here. We’ve said it many times. When we come here, although we have that big goal of winning the championship, our priority is always to win races and win every single weekend,” insisted Palou. “Even though could have been OK to stay third, we wanted to win.”
