The Lucas Oil Late Model Dirt Series Big River Steel Chase for the Championship begins with this weekend's Pittsburgher at Pittsburgh's Pennsylvania Motor Speedway.

Nearly 40 drivers are signed into Friday's preliminary action at the half-mile that hosts Saturday's $50,000-to-win finale of the 36th annual Pittsburgher. The Big River Steel Big Four drivers, Ricky Thornton Jr., Jonathan Davenport, Devin Moran and Tim McCreadie, are among those signed in.

The Big River Steel Big Four begin their title chase after rainouts at Brownstown (Ind.) Speedway and Atomic Speedway in Alma, Ohio. Ricky Thornton Jr. enters this weekend as a two-time Pittsburgher winner, including last year’s $30,000 top prize.
