BIRMINGHAM, Ala. -- Zach Veach earned his second Indy Lights Presented by Cooper Tires race of the season and stretched his championship points margin to 26 over Long Beach race winner Gabby Chaves in the Legacy 100 at Barber Motorsports Park -- the first of two races on the 2.38-mile, 17-turn road course.

The Andretti Autosport driver, who started from the pole, led Luiz Razia across the finish line by 3.844 seconds in the 30-lap contest. Jack Harvey, Razia's Schmidt Peterson Motorsports with Curb-Agajanian teammate, finished a season-best third and is third in the championship standings.

Veach, 19, of Stockdale, Ohio, led every lap, maintaining a 3-second gap on Razia over the final 10 laps.

“We were very happy to use the pole to our advantage," said Veach, who swept the maximum 53 points for the victory and bonus points for the Sunoco Pole Award and leading the most laps. "Didn’t get that opportunity at Long Beach, but it was a great car to drive. I want to thank my Andretti Autosport team for doing that. This car was easy to drive. It was really consistent and I’m excited to go out and turn laps (in Race 2). Just got a couple of things to change, but we’ll be right back up there.”

Matthew Brabham of Andretti Autosport finished fourth and Alex Baron placed a season-high fifth in the No. 4 Belardi Auto Racing car. Chaves, who started third in another Belardi Auto Racing entry, finished sixth. Chaves, the Indy Lights championship runner-up in 2013, is 26 points behind Veach.
