CONCORD, N.C. (AP) — Brad Keselowski extended Jimmie Johnson’s losing streak to 102 races by holding off the seven-time NASCAR champion in overtime early Monday in the Coca-Cola 600. Keselowski started in the back of the field, worked his way to the front at Charlotte Motor Speedway and gambled in not pitting when caution stopped Chase Elliott from winning with two laps remaining. Elliott pitted and Keselowski led a train of eight cars that stayed on the track. He lined up in front of Alex Bowman on the inside line with Johnson on the bottom ahead of Keselowski teammate Ryan Blaney. Keselowski got the push to get into clean air and denied Johnson a victory.
