It was 21 years ago at TPC Scottsdale, when a horde of fans helped Tiger Woods move a boulder that was blocking his approach shot at the Phoenix Open.
The boulder was by loose definition a loose impediment.
Last year, some fans helped Brooks Koepka, who was in a similar situation in Saudi Arabia.
The scene played out again on Thursday at the Saudi International. But, unlike Koepka and Woods, Alvaro Quiros offered his own assistance and needed only a couple of caddies to help.
