Sunday May 7, 1972 – Davie Pearson managed to swing around trouble when it struck race leader Bobby Isaac and the result was a victory in the Winston 500 at Alabama International Motor Speedway for the Wood Brothers Racing driver. Pearson was trailing Isaac with two laps remaining when the leader hit the wall after contact with the lapped entry of Jimmy Crawford.
• Isaac, who still managed to finish second in spite of his skirmish with Crawford, had ignored a black flag from NASCAR due to an unattached gas cap as the final laps wound down. He was allowed to keep his runner-up finish but fined $1,500. NASCAR president Bill France Jr. said afterward that officials had the option of penalizing, disqualifying or suspending Isaac for the infraction. “It isn’t easy inspecting a car going 190 mph,” France told reporters.
• Asked how the call could have differed had Isaac won the race instead of finishing second, NASCAR Vice President Lin Kuchler said, “I guess we’d still be meeting.”
• Richard Petty finished fifth and earned a $10,000 bonus for leading the points standings after the season’s 11th event. Another $10,000 was split among the drivers second through fifth in the standings after the race.
• Country music star and sometimes racer Marty Robbins finished 18th in the race to earn Rookie of the Race honors. However, officials stripped Robbins of his finish for an improperly installed carburetor, leaving him last in the 50-car field.
• The race saw the debut of Darrell Waltrip in NASCAR’s premier series. Waltrip qualified 25th and finished 38th in the No. 95 Terminal Transport Mercury. It was the first of 809 career starts in the series for the three-time champion and NASCAR Hall of Fame member.
