The Masters starts today in Augusta, Georgia, and most of the focus is on Tiger Woods. But Germany's Martin Kaymer is also getting a lot of attention, because of something he did on Monday.

During the practice rounds at Augusta, it's a tradition to try and skip your ball across the water on the 16th hole, which is a par three. And Kaymer not only did it...he got a HOLE-IN-ONE!

Someone got cell phone footage of it, and posted it on YouTube. The second shot is Kaymer's. He swings at :17.
