Sam Mayer damages wall in 25-car crash at NASCAR O'Reilly San Diego race

A simple misjudgement in the NASCAR O’Reilly Auto Parts Series race at San Diego heavily damaged the wall and several race cars on June 20.

Sam Mayer, running inside the top 10, misjudged the entry into turn 1 during a Lap 35 restart in the United Rentals Driven to Serve 250, brushing the inside wall before shooting back left to the outside wall at near-full speed.

Mayer collected several other cars, including Anthony Alfredo, in the multi-car crash.

His impact with the outside wall caved the temporary barrier in by several feet while also damaging the catchfence in turn 1.

Alfredo was in the crash and out of the race. Others in the accident included Sheldon Creed, Brent Crews, William Sawalich, Sammy Smith, Jeb Burton, Preston Pardus, Brennan Poole, Blaine Perkins and Jeremy Clements. In all, NASCAR listed 25 cars as involved in the crash.

NASCAR displayed the red flag soon after the impact, and track crews were sent to make major repairs to the concrete wall barrier and catchfence. At least two cranes were sent over to the area near pit road for the fix.

The O’Reilly Auto Parts Series race included six cautions and two red-flag periods through the first 35 laps. A manhole cover was dislodged during the opening lap and buried into Corey Day’s radiator and grill opening.

Day was allowed to make repairs under the red flag as NASCAR welded two manhole covers and got his laps back under caution.
