Rinus VeeKay turned the fastest lap in the morning warmup with a lap of 0.59.8987 seconds. The session saw many cars overshoot turn 3 and some close calls on pit road. Alexander Rossi was the only other driver to lap in under a minute, trailing VeeKay by about 5 hundredths of a second.
Polesitter Colton Herta had an eventful session. He stalled leaving pit road when he has to stop to let another car by, then later went into the turn 3 runoff area and stalled, bringing out the only red flag of the practice period.
Herta also was involved in a close race off pit road with two other cars who were nearly three wide at pit exit.
Tire marbles were strewn across the track, and when cars came into the pits lots of debris was on the tires.
This could be a high attrition race.
