A pre-session downpour delayed the start of practice, and when it did run for 30 minutes, Ericsson lapped the 2.1-mile temporary street course in 1m31.7999s.
Ganassi’s series dominator Alex Palou was one of the first cars on track, setting the bar at 1m35.0152s, and was also the first to find the run-off at Turn 11, requiring a spin-turn to get back on track.
