For the second time in two weeks in the Indianapolis area, a young Canadian scored his first victory in the Pro Mazda Championship Presented by Cooper Tires. This time it was Garett Grist, driving for Andretti Autosport, who led from flag to flag in Saturday evening’s Allied Building Products Oval Challenge at the 0.686-mile Lucas Oil Raceway oval as part of the 69th Annual Visit Hendricks County Night Before the 500.
