A major incident in the NASCAR O’Reilly Auto Parts Series race at San Diego on June 20 led to heavy damage after a Lap 35 final-stage mistake triggered a multi-car wreck.
Sam Mayer's misjudged entry triggered crash, sending his car into Anthony Alfredo and forcing both vehicles into the outside barrier.
The impact was so severe that the temporary wall shifted nearly a meter, prompting NASCAR to immediately red-flag the race.
Both Mayer and Alfredo were evaluated and later released from the medical center, though Anthony Alfredo appeared to be limping afterward.
A total of 25 cars were involved in the incident, including Sheldon Creed, Brent Crews, William Sawalich, Sammy Smith, Jeb Burton, Preston Pardus, Brennan Poole, Blaine Perkins, and Jeremy Clements.
Track crews were forced to remove and replace the damaged portion entirely, leading to a lengthy cleanup period of roughly 45 minutes.
