After hitting a putt during the 2003 U.S. Senior Open, a gust of wind knocked Wayne Levi's hat off, causing it to blow right past the ball, very close to making contact.

In the 1986 NEC World Series of Golf Denis Watson's ball was intentionally deflected onto the green by an outside agency, which in this case was an overzealous fan.

Bob Murphy’s ball had company in this bunker during the first round of the 2003 U.S. Senior Open… belonging to his fellow competitor, Hubert Green. Green’s ball struck and moved Murphy’s ball then came to rest on the spot where Murphy’s ball had originally been located.

On the Par 3 12th hole of the final round at the 2003 “AT&T Pebble Beach National Pro-Am,” Davis Love’s tee shot hopped over the green… but he got a lucky break when the ball found a photographer’s leg.

Payne Stewart’s chip shot at the 1991 PGA Championship was deflected by a leaf on the putting green and found its way into the hole. Natural objects – and that includes leaves – are loose impediments. However, this leaf also has the status of an “outside agency.”
