Three races remain in the IndyCar Series, including the Grand Prix of Portland at Portland International Raceway this week, and it's anybody's guess as to who will be crowned champion.

It's been Scott Dixon's series in the past with the Chip Ganassi Racing driver winning six championships, including last season, when the series had to skip Portland because of the COVID-19 pandemic. But, a couple of upstarts sit atop the point standings: Pato O'Ward from Arrow McLaren SP (435) and Ganassi's Alex Palou (425). Hot in pursuit are Team Penske's Josef Newgarden (413), Dixon (392) and Ganassi's Marcus Ericsson (375).
