With a green flag start just after 3 p.m., and no lights at the concrete mile track, NASCAR faced a tight window to reach the halfway mark needed for an official race Sunday at Dover. They made it to 78 laps before rain set in. So they’ll fire the engines again at noon Monday with Hendrick Motorsports teammates Kyle Larson and Chase Elliott starting 1-2. Ryan Blaney is third, Truex is fourth and William Byron fifth.
