The shot was playing all up hill, yardage 191 and playing 210 to an elevated green, the pin was in the back and you had to carry a front bunker. Since you couldn't see the ball go in the hole because of the elevated green, upon approach, I said "where is my ball"? A member of our foursome, said "why don't you look in the hole"! And there it was, a Titleist NXT Tour 4, in the hole. My first hole in one after 56 years of golf!
