The Definition
A hole-in-one (also called an ace) is completing any hole in a single stroke — the ball travels from the tee directly into the cup. Holes-in-one occur almost exclusively on par 3 holes, where the green is reachable in one shot. Making a hole-in-one on a par 4 or par 5 is extraordinarily rare and requires holing an approach shot or tee shot from enormous distance.
The Odds of Making a Hole-in-One
The National Hole-in-One Registry estimates that the odds of an average amateur golfer making a hole-in-one on any given par 3 attempt are approximately 12,500 to 1. For a tour professional, the odds drop to around 2,500 to 1 due to superior accuracy. Over the course of a full golfing career (2,000+ rounds), a golfer playing to a 15-20 handicap has roughly a 1 in 6 chance of making a hole-in-one at least once.
What Factors Increase Your Chances
Several factors improve hole-in-one probability: shorter par 3 yardage (under 150 yards), accurate iron play (especially from 100-150 yards), good ball-striking conditions (firm greens that allow the ball to check), favorable pin positions (front of green rather than back), and playing frequently on courses with shorter par 3s. Weather matters too — calmer conditions allow for more predictable ball flight.
The Tradition of Buying Drinks
Golf tradition holds that a golfer who makes a hole-in-one buys drinks for everyone in the clubhouse. This tradition dates back to early Scottish golf. Many golfers purchase 'hole-in-one insurance' before large tournaments that pays out a fixed amount to cover the celebratory bar tab. The tradition varies by country and club culture but is widely observed as a joyful celebration of an exceptional achievement.
Hole-in-One in Professional Golf
PGA Tour professionals average roughly one hole-in-one per 3,000 rounds collectively. The record for most career aces on tour belongs to Hal Sutton with 11. Tiger Woods has made multiple holes-in-one on tour. The most famous hole-in-one in major championship history may be Nick Price's ace on the 8th hole at Augusta National in the 1996 Masters, or Jack Nicklaus and Tony Jacklin's simultaneous 17th hole aces at the 1971 Ryder Cup.
