i dont know what the spins got to do with it,when u hook or slice the ball it takes a considerable amount of strength off the shot, ok, you've left the bunker with a hook or pull or stopped it short whatever you wanna call it ok, it hasn'nt made it and hit the rocky wall in front of the green, im positive! from then you had urself a pinball effect, how can you say it didnt hit a rock, its pretty audible to me.
