Kaymer, 27, nailed it on the 16th hole in front of a rapturous crowd during a practice of the US Masters at Augusta National.
Rather than flicking the ball over the water hazard, as most players would have done, the former World No 1 German golfer drove it straight across the pond.
The game hasn’t seen ball sink in one like that since Vijay Singh’s effort on the same hole at the 2009 Masters.
Needless to say, Kaymer is feeling positive.
He told the European Tour website: “I feel a lot better about my game this year than I did last time.
“I’ve changed a few things in my swing and they are working well.
“A few tee shots at Augusta don’t really suit my eye, but it’s obviously a great course and it’s up to me to try to find a way to play it.
“Hopefully playing a practice round with Bernhard (two-time winner Bernhard Langer) will help me.
“The great thing is it’s probably the biggest challenge that I have, so I’m really looking forward to trying to win that challenge.
“I’m much more confident than I have been in the past. I’m really excited about it.”
