Ace (Hole-in-One)
Holing the ball with a single stroke, straight from the tee.
The odds are genuinely long: the National Hole-in-One Registry puts the average golfer's chance at roughly 1 in 12,000 per attempt, meaning most players go decades between aces, if they ever make one at all. Better players fare considerably better, low-handicap golfers are closer to 1 in 5,000.
