Esteban Guerrieri takes late-night Indy Lights win at Iowa

Thunderstorms late in the afternoon forced the race to be rescheduled until after the IndyCar event, meaning that it was just past midnight before the green flag was waved.

Guerrieri took the lead when polesitter and Sam Schmidt Motorsport team-mate Tristan Vautier was issued a drive-through penalty for blocking. Once in front, his only real scare came when another Schmidt driver, Oli Webb, hit the wall and brought out a late yellow, forcing Guerrieri to defend himself against Team Moore's Gustavo Yacaman on the restart.

The Argentine driver saw off the challenge and claimed the win by 0.4 seconds, with the fourth Schmidt driver Victor Carbone crossing the line behind Yacaman to complete the podium. Vautier rallied back from his penalty to finish fourth.

Championship contender Sebastian Saavedra (Andretti Autosport) was forced to drop out of the race early with a mechanical problem.
