Sunday, April 29, 1973 – The Virginia 500 at Martinsville (Va.) Speedway was your typical exciting short-track race, ending with David Pearson in victory lane following a lengthy late-race duel with Cale Yarborough. The pair battled for the top spot for more than 50 laps before Yarborough spun his No. 11 Chevrolet, leaving Pearson to sail away in his No. 21 Wood Brothers Ford. But it was a caution on lap 374 of the 500-lap race that left Yarborough and team manager Junior Johnson feeling robbed.
• NASCAR officials threw the caution flag to allow an ambulance to exit the track and transport a heart attack victim to a local hospital. Pearson, two laps down earlier in the race, got back on the lead lap when the yellow appeared and after Yarborough had pitted under green moments earlier. Johnson said teams weren’t told the yellow was going to come out and the move “cost us that race.”
• The victory was Pearson’s first at Martinsville, one of 11 victories in only 16 starts that season for the Spartanburg, S.C. native.
• Yarborough, who led 314 laps, managed to finish second in spite of his late-race spin. Bobby Isaac, Buddy Baker and Cecil Gordon completed the top five.
