It doesn't matter whether you are a professional golfer or an amateur - we've all had that incredibly frustrating moment when a ball plops into the water. What can you do but leave it behind, take the penalty, and move on.
But that option wasn't available to Dustin Johnson. With his brother Austin on the bag as his caddy, Dustin handed his brother his ball whilst safely on the 17th green, only for Austin to accidentally drop it into the water.
The rules state that you must finish the hole with the ball that you reach the green with - you can't switch it out. Meaning that Austin jumps into the water to retrieve the ball - with a cast on his hand. Austin even decided to jump in without taking his shoes off.
When your little brother drops your ball in the water, he has to go get it (even if he's your caddie)... https://t.co/aBYYmBBZ25

It might be the first, and last, time he messes around with a golf ball around water.
