Carlos Munoz, runner-up in the Firestone Freedom 100 in the No. 26 Team Dialy-Ser car for Andretti Autosport, closed on Yacaman in the final lap to finish 0.1638 of a second behind. It was the second-closest road/street course finish in the series.
The race, scheduled for 45 laps, was switched to a timed event because of extended barrier repair from a Lap 14 incident involving the No. 15 Younessi Racing car driven by Peter Dempsey. Forty laps were completed. Dempsey was checked and cleared to drive.
Webb finished third in the No. 7 Lucas Oil/Sam Schmidt Motorsports car to match his best in Firestone Indy Lights, and teammate Victor Carbone was fourth in the No. 3 Mav TV/Nevoni/SSM with Curb-Agajanian car. Tristan Vautier, driving the No. 77 Mazda Road to Indy/SSM with Curb-Agajanian car, was fifth.
Sebastian Saavedra, driving the No. 27 Team AFS car, and the No. 11 Pistas Argentinas/SSM with Curb-Agajanian car driven by Esteban Guerrieri made contact on the final lap and Race Control altered the finishing order to place Saavedra in sixth and Guerrieri in seventh.
Guerrieri, the Firestone Freedom 100 winner, retained the top spot in the series championship standings by 15 points over Vautier (188), who was docked five championship points by the Firestone Indy Lights Race Director for failure to follow rules as instructed in the race day drivers meeting at Indianapolis. Saavedra is one point behind in third.
