Friday 13th September 1968
Bobby Isaac took advantage of pole-starter Cale Yarborough’s crash near the midway point to win the Maryland 300 at Beltsville Speedway, Maryland, US. Isaac, who drove a Nord Krauskopf-owned Dodge, led the final 158 laps after Yarborough’s wreck to notch his third and final win of the season. David Pearson finished eight seconds behind Isaac, but was disqualified from second place when his car was ruled too light in the post-race inspection. That moved Bobby Allison to second and Richard Petty to third in the final rundown on the half-mile asphalt track.
