“We did a lot of really good work overnight,” O’Ward said. “We got her in the window. It feels a lot better than it did yesterday. Yesterday was really messy.

“It’s such a long track where if you’re really struggling with a balance issue, you’re going to lose so much. But if you have something you’re comfortable with and you can hustle, it’s obviously rewarding. We’re looking forward to qualifying. Who knows what reds (Firestone alternate tires) are going to do?”

NTT P1 Award qualifying is next, at 1:45 p.m. (ET). Peacock Premium and the INDYCAR Radio Network will provide live coverage.
