Ross Chastain and Austin Dillon each were assessed 30-second penalties for short-cutting the Indianapolis Motor Speedway Road Course in the closing laps of Sunday’s race.
A trio of late restarts saw multiple front-runners spin while battling for position in treacherous Turn 1. On the final restart of the race, both Chastain and Dillon zoomed down an access road to avoid the incidents happening in front of them, then drove back onto the track.
Chastain appeared to take the lead from Tyler Reddick with a slick pass in the esses, but Reddick eventually re-took control and powered on for his second win of the season.

Chastain’s Trackhouse Racing Chevrolet initially came home in second place before NASCAR officials issued the penalty, which then dropped the No. 1 to a 27th-place finish. Dillon was already a lap down and slipped a couple of spots in the final order to 30th.
