Andretti Autosport’s Grosjean was fastest initially in the top six pole shootout with a 1m06.0289s, 0.0341s ahead of Pato O’Ward of Arrow McLaren, but on fresher tyres Team Penske’s Scott McLaughlin displaced him at the head of the times.
However, Grosjean, who lost an engine yesterday, delivered a 1m05.8396s with his fourth lap and it was Alex Palou of Chip Ganassi Racing who came closest, just 0.0734s adrift.
It is the second pole of the season for Grosjean, and the fifth of his IndyCar career.
The top four were covered by just 0.112s, as O’Ward was a hair quicker than McLaughlin to take third.
Scott Dixon made it two Ganassi cars in the top five, ahead of the impressive Lundgaard of Rahal Letterman Lanigan, just 0.32s from the top spot.
In Q2, two Penskes of Will Power and Josef Newgarden dropped out, while Andretti and winner last time out Kyle Kirkwood spun on cold tyres exiting the pits to see his early exit confirmed.
