If you have ever played golf you would have seen that happen dozens of times. The ball is round and has a tendency to stop and start on slopes and at the edge of holes. its not fixed, just VERY VERY LUCKY tiger.
tiger gets tons of breaks. Whenever i hit the ball in the trees is bounces under a bush and behind a tree. He hits it in the trees and it either bounces back onto the fairway or with a chance to punch it out.
