SPARTA, Ky. — Brad Keselowski became the first three-time winner at Kentucky Speedway on Saturday night, overtaking Kevin Harvick on lap 201 and holding on for the Sprint Cup Series victory. Matt Kenseth grabbed the lead with six laps remaining but soon pitted for fuel to hand the top spot back to Keselowski, who had just enough gas in reserve to edge Carl Edwards by .175 seconds in a tense finish for the 400-mile race. Keselowski’s tank eventually ran dry and he needed a tow truck to get to victory lane.
