Ron Burke is a numbers guy. You would expect as much from a trainer juggling a 250-horse stable of trotters and pacers who has been the best in the harness business for a decade. Burke, based in Washington, Pa., at The Meadows, as well as a nearby farm, never misses one of his pupil’s starts, be it in person or via a computer or television screen. He will have his eye on the mobile starting gate Sunday (Dec. 2) when he sends out both Filibuster Hanover and Rockin Ron in the $100,000 Potomac Pace at Rosecroft Raceway.
