Colton Herta had worked down to a 1m12.9450s in his Andretti Herta Autosport, when Graham Rahal spun his Rahal Letterman Lanigan exiting the top of the Corkscrew and stalled, causing a red flag.
Juncos Hollinger Racing’s rookie Callum Ilott delivered a 1m12.34s, then a 1m11.9899s to go top ahead of fellow rookies David Malukas and Christian Lundgaard. As in Portland, Ilott was shining at a track where he gained experience last year, and he was over three-tenths of a second clear of his nearest rival at the time.
