Teenage sensation Matthew Brabham continued his successful season by winning his 12th race in the Pro Mazda Championship at the Reliant Park street course in Houston.
Braham, 19, led all the way after starting from pole position in his Andretti Autosport prepared #83 machine.
His winning tally is a season record while he also posted his 12th fastest lap in the race which breaks the record set last year by Jack Hawksworth.
“The guys are doing such a great job here at Andretti Autosport,” Brabham acknowledged.
“We were fast this weekend and already had the championship wrapped up, so I'm just out there having fun and really enjoying it.
“It's pretty exciting. The track is kind of different every time we go out; it's a lot of hard work and fitness is really coming to play, but I'm having a blast.
Brabham will line up for tomorrow's 16th and final Pro Mazda Championship Powered by Cooper Tires race in pole position.
