Fontana Indy Lights: Carlos Munoz wins, Tristan Vautier secures championship

Munoz inherited the lead when Andretti team-mate and polesitter Sebastian Saavedra's car suffered a mechanical problem at the start, and was never headed. David Ostella crossed the line 0.6 seconds behind him to claim second.

Vautier and title rival and Sam Schmidt team-mate Esteban Guerrieri spent much of the race hanging just off the back of the leaders, although the key move came when Guerrieri passed Vautier for third with 10 laps remaining.

But that still left Vautier with an eight-point buffer, meaning that Guerrieri had to close down the 1.5s gap to Ostella and then find a way past the Team Moore Racing driver.

Instead, Ostella was able to extend his lead over the final laps, eventually crossing the line 2.7s clear of Guerrieri and ending the Argentine's title hopes.

Victor Carbone was fifth, but the main action in the final phase of the race was the three-car battle for sixth, which was eventually settled in favour of Stefan Wilson ahead of Bruno Palli and Oliver Webb.
