Andretti Autosport’s Alexander Rossi has set the pace in Final Practice ahead of the Portland IndyCar race.

With no Sunday morning (local time) Warm Up, the field got a 30-minute session in the hours after Qualifying, Rossi prevailing on a 0:59.0532s in the #27 Honda.

Christian Lundgaard (Rahal Letterman Lanigan Racing) took second on a 0:59.1806s and Alex Palou (Chip Ganassi Racing), who had the longest spell on top of the timing screen, ended up third on a 0:59.2196s.

First of the Chevrolet drivers was Team Penske’s Josef Newgarden in fourth having gone as quick as a 0:59.2662s.

However, it was his team-mates Scott McLaughlin and Will Power, who will start from the front row, setting the pace in terms of 10-lap averages.

Newgarden had qualified second-fastest but is set to start from eighth due to a grid penalty for an unapproved engine change.

All 25 drivers ran on primary tyres throughout the half-hour hit-out, although reds are thought to be the preferred compound for the 110-lapper.

Earlier, between Qualifying and Final Practice, IndyCar advised that the start location had been moved back in a bid to avoid significant carnage at the chicane.

Race start is tomorrow at 05:30 AEST, with Stan Sport’s live and ad-free coverage kicking off at 05:00 AEST.
