pencer Pigot bounced back from a series of misfortunes to score a commanding victory in today’s second leg of the Allied Building Products Pro Mazda Grand Prix of Houston Presented by Marlin CNG Services. Starting second on the grid, Pigot, 20, from Orlando, Fla., made an explosive start, then dived to the inside of polesitter Garett Grist under braking for the tight chicane at Turn Two on the unforgiving 1.7-mile MD Anderson Cancer Center Speedway at NRG Park. He remained under pressure from fellow American Neil Alberico for the first dozen or so laps, then edged clear to win the 30-lap race by almost four seconds.
