This might be a first for professional golf.
The final round of the 2021 U.S. Open at Torrey Pines had a brief incident when a male streaker ran onto the course and attempted to hit a couple of shots from the fairway. After a few shots, he started to dance, before alluding security.
He eventually got taken down.
The streaker emerged onto the 13th fairway just as reigning US Open champion Bryson DeChambeau was making a mess of the first of two back-nine par 5s at the US Open host.
