Inevitably, after a warm-up lap at the start of the session, the veterans parked and let the rookies use their extra set of primary tyres to clean the track and add grip to the surface already christened with Firestone rubber thanks to the Indy NXT cars on track earlier in the afternoon.
Despite a lurid moment at Turn 9 in his #11 Chip Ganassi, Marcus Armstrong was the first to lap the course at an average of over 122mph on his sixth lap, producing a 1m07.7542s around the 17-turn 2.3-mile course.
