The Brabham family finally has a victory to its credit at the Indianapolis Motor Speedway after third-generation racer Matthew Brabham won the front end of the two Indy Lights Presented by Cooper Tires races on the new road course.

Brabham, who had qualified the No. 3 Andretti Autosport car on the pole earlier in the day, held off a race-long challenge on a rapidly drying track from Brazilian GP2 graduate Luiz Razia to score his first Indy Lights race win. Brabham, 20, now has added a race win at the highest level of the Mazda Road to Indy after winning titles in the Cooper Tires USF2000 Championship Powered by Mazda and the Pro Mazda Championship Presented by Cooper Tires.

The track was soaked after a rain shower immediately following the Pro Mazda race, so every competitor had no choice but to start on grooved Cooper tires.

"It was pretty crazy out there for sure. At the end, it was dry and we were running on the Cooper Tire wets," Brabham said. "It was really sketchy in the fast corners but they did a really good job of holding up. They lasted until the end of the race and there was still grip there to make it around so I am very happy."

Brabham, whose grandfather, Sir Jack Brabham, pioneered the rear-engined revolution at the Indianapolis 500 in the early 1960s and whose father, Geoff Brabham, made 10 Indy 500 starts (with a best finish of fourth in 1983), led away from the pole but came under pressure almost immediately from Gabby Chaves, who had already won two races this season for Belardi Auto Racing.

As the track began to dry quite quickly, drivers started to seek damp patches on the road surface to prevent their wet-weather tires from overheating. Razia gradually whittled the deficit to Brabham to less than a second, but he was able to get no closer. Razia had to be content with second, while Schmidt Peterson Motorsports with Curb-Agajanian teammate Jack Harvey charged hard to climb from seventh following an early miscue to third at the checkered flag.

Zack Meyer (Team Moore Racing) earned a career-high fourth, while Alex Baron held on for fifth.
