FORT WORTH, Texas – NASCAR Xfinity Series championship favorite Chase Briscoe will start from the pole during Saturday’s O’Reilly Auto Parts 300 at Texas Motor Speedway. Briscoe earned the top spot on the grid thanks to NASCAR’s metric qualifying formula. The NASCAR matrix factors in a driver’s lap speed ranking from the previous race, the last race finish for both driver and owner and the car’s current rank in the owner standings. Lap speed is weighted at 15 percent, previous race finish at 25 percent for the driver and owner results and owner points position at 35 percent to calculate the final metric score.
