HyVee Perks 250 grid watch
The O'Reilly field mixes developing drivers with experienced regulars, so adaptation can reshape the order quickly. Watch entry bumps, upper-lane momentum and tires-versus-track-position calls. The approaching cutoff makes the provisional Chase bubble part of the race story. For this event, the season role is O'Reilly regular-season race 23 of 24.
Starting-order facts checked against ESPN Core. A post-qualifying inspection or unapproved adjustment can still send a car to the rear without changing its scored starting position.
