Oh, come on.....these guys are Pros; they hit the ball from the tee in such a way that when it hits a solid green, the back "English" makes it roll backwards.
A downward slope towards the pin helps matters out too.
BTW, Jack has probably played that same hole hundreds of times.
A great deal of skill, a grate deal of practice,a great deal of luck, and huge karma.
Thanks for the explanation. During the few times when I play golf, that never happens for me. The ball just hits the ground and keeps rolling forward to a stop. Hopefully it does not stop in the water or in the woods.
