David Horsey had found the hazard on the par-5 ninth hole in the opening round of the European Tour’s inaugural D+D Real Czech Masters. He needed to identify his golf ball to make sure of point of entry, but the ball had gone far enough into the hazard that it wasn’t as simple as rummaging around the lake bed with a club.
So, Horsey sent in his caddie with a club to go grab the ball and identify it. The caddie heads into the hazard, forages around for a little bit, going deep enough to get his clothes wet and finds the ball. And that was all so Horsey could make a bogey.
