Steve David and Jimmy Shane each won heat races during the first day of competition at the Diamond Cup in Coeur d’Alene on Saturday.
Shane won Heat 1A driving the 5 Graham Trucking, but he got a challenge from Tom Thompson in the 11 Peters & May before hanging on to the victory.
David, in the 1 Oh Boy! Oberto, had to overcome J. Michael Kelly — who was on the inside lane in the 37 Miss Beacon Plumbing — to take the victory.
Racing resumes at 11 a.m. Sunday, with the final scheduled for 4 p.m.
