What won the race: Overtaking Brandon Overton on the 35th lap, Dillon McCowan of Urbana, Mo., completed a shocking sweep of the Lucas Oil Late Model Dirt Series in the $25,000 CMH Diamond Nationals in thrilling his home-track fans at Lucas Oil Speedway. The fifth-starting McCowan scored back-to-back career biggest victories in taking the checkers 1.730 seconds ahead of Garrett Alberson to add Saturday's triumph to Friday's $15,000 payday, giving him two national touring wins.

On the fourth lap, Hudson O'Neal and Payton Looney spun in turn two. ... Billy Moyer slowed on the 31st lap. ...
