Astor Challenge Cup

The NTT INDYCAR SERIES’ 2021 championship chase is effectively down to five drivers with three races remaining, the first of which is Sunday’s Grand Prix of Portland at Portland International Raceway (3 p.m. ET, NBC and the INDYCAR Radio Network).

Here’s a look at what’s at stake and a driver-by-driver forecast of their best path to victory.

The Remaining Schedule: There are two permanent road courses and a street circuit still to host races. After Sunday’s race at Portland, the series will travel down the West Coast in consecutive weekends to race at WeatherTech Raceway Laguna Seca (Sept. 19) and the street circuit in Long Beach, California (Sept. 26).

The Prize: First place comes with a $1 million bonus and a place on the Astor Challenge Cup.

What Recent History Shows: Since 2008, the biggest deficit a champion has erased over this span is 49 points (Scott Dixon in 2013). This year, fifth-place Marcus Ericsson of Chip Ganassi Racing is 60 points out of the lead, suggesting he has a lot of work to do to earn his first series title. The driver leading at this stage of the season has won the past five championships and six of the past seven.

The Primary Combatants: Three drivers from Chip Ganassi Racing (Alex Palou, Scott Dixon and Marcus Ericsson) and one each from Arrow McLaren SP (Pato O’Ward) and Team Penske (Josef Newgarden). The three Ganassi cars are powered by Honda, the other two drive with Chevrolet.

Their Trips to Victory Lane: The five drivers have combined to win nine of the 13 races this season, with O’Ward, Palou, Newgarden and Ericsson winning two races each. Dixon has won one.

The Standings: O’Ward leads Palou by 10 points with Newgarden in third, 22 points out of the lead. Dixon trails O’Ward by 43 points, with Ericsson 60 back. With 27 cars expected at each of the remaining races, the most a driver can gain in a weekend is 49 points. That means there are 147 points to gain, essentially eliminating all other drivers as the sixth-place driver is 111 points out of the lead.
