CONCORD, N.C. — Brad Keselowski snapped a 37-race winless streak Saturday night by chasing down Kasey Kahne in the closing laps at Charlotte Motor Speedway. The defending Sprint Cup Series champion, who failed to qualify for the Chase this year, grabbed his first win of the season and first since Sept. 30, 2012, at Dover, by passing Kahne with nine laps to go in his Penske Racing Ford. Keselowski became the first non-Chase driver to win a Chase race since Jamie McMurray at Charlotte in 2010.
