Five inches of rain from Hurricane Beryl that soaked Tri-City Speedway for track and series officials to postpone Friday's Lucas Oil Late Model Dirt Series event at the Granite City, Ill., oval. No makeup date was immediately announced for the $12,000-to-win NAPA Know How 50.

The rainout shrinks Lucas Oil's scheduled three-race weekend to two events. The $15,555-to-win Slocum 50 is scheduled for Thursday at 34 Raceway in West Burlington, Iowa, followed by Saturday's $20,000-to-win CMH Diamond Nationals at Lucas Oil Speedway in Wheatland, Mo.
