Colton Herta has just one more session to lead as he turned the quickest time in this morning’s 30 minute warmup session.

The tune-up was interrupted about halfway through when Toby Sowery spun and stalled facing the wrong way off of turn 10. Even if he had been able to restart the car on his own, it would have been difficult know when it would have been safe to move because he was in a blind spot.
