The Odds Of Making A Hole-In-One

Every golfer dreams of making that magical Hole-In-One! I think about it every time I play the par3 17th hole at my home course. There’s a bench engraved with the name of one of our league who made an ace happen a few years ago. And a few months ago I witnessed one of my golf partners sink an ace on the par3 7th hole at our partner course. It still hasn’t happened for me, sigh. But that got me thinking – what are the odds of making a hole-in-one?

Guest author, Phil Blackwell tells the story of Patrick Wills, an American amateur golf who once scored three holes-in-one in a single round!  The infographic Phil created (pictured below) was produced on the back of a survey he did in the UK which showed that 79% of Brits underestimate their chances of getting a hole in one (women are more confident than men) – odds can actually be as low as 5,000/1.



A stroke of luck? The truth about hole-in-one odds

The life of a golfer is scattered with moments of personal magic.

Your very first eagle; that perfect chip from the bunker; the undulating long-distance putt that clinched the game…

But, few events are more memorable than scoring a hole-in-one.

The odds of scoring an ace stand at 12,500/1 for an average golfer, but can be as low as just 2,500/1 for a professional. Only last year, amateur golfer, Patrick Wills, hit three in a single round.

Score CardSo is it any wonder that in a tournament field of around 150 players, playing four rounds each, the chances of a hole-in-one occurring are even better still.

With 600 rounds being played and the odds of each professional standing at just a fifth of an average player, there is actually a 24% chance of an ace being scored.

Perhaps not so unlikely after all.

The Hole-in-One Gang

In 1991, two British men, nicknamed ‘The Hole-in-one gang’ calculated the probability of a hole-in-one being scored during any professional golf tournament at the time as no more than even money.

By exploiting the miscalculations of bookmakers, the pair won over £500,000 and were refused another twelve payouts as a result of various legal disputes.

This classic example of misjudged probability highlights the general failure of humans to perceive luck and chance.

How to hit a hole-in-one

A recent survey by, revealed that 79% of Brits significantly underestimate their chances of hitting a hole-in-one by at least three times.

So what can you do to increase your own chances?

  1. Practice: A lower handicap equals a higher chance. Give yourself the opportunity to be lucky, increase your short game to beat the long odds.
  2. Play shorter courses: Obvious, but effective (crazy golf doesn’t count). Although it’s possible to hit an ace on a par four or even a severely dog-legged par five, it’s also much more difficult.
  3. Play the same course: Benefit from the familiarity of each hole, their dangers and unique characteristics

The odds of an ace

Even without taking action to shorten them, odds of 12,500/1 are actually quite low when compared to even more unlikely events.

  • Winning the Powerball Jackpot – 292,201,338/1 (23,376 x longer)
  • Being declared a saint – 20,000,000/1 (1,600 x longer)
  • Dying in a plane crash – 11,000,000/1 (880 x longer)
  • Getting a royal flush in poker – 30,939/1 (2.5 x longer)

Are you feeling confident? Somebody wins the Powerball every few months, right? And, news channels are always talking about plane crashes. A hole-in-one should be simple.

But, before you run off to the golf course, bear in mind the following from Professor David Hand, author of The Improbability Principle:

“If something is so improbable that it’s unlikely to happen during your lifetime, or during the history of the universe, then it’s only sensible to treat it as impossible. This is called Borel’s Law. Winning the lottery is an example.

“What people fail to allow for is the fact that, while the chance of any one particular person winning is very small, if enough people play then it becomes likely that someone will win.

“And then the publicity raises people’s awareness of the possibility of winning, so distorting their impression of the probability of winning.”

Fore-tune favours the brave

Next time you step up to the tee on your favourite par three, don’t put pressure on yourself to ace the hole. Relax in the knowledge with for every drive, chip and putt, you’re moving one step closer to that elusive, yet achievable, goal: your first hole-in-one.

    I have hit 4 hole in ones in 15 month. what are the odds of that for an amateur golfer?

  2. Ken Barnard says:

    Didn’t anyone check the photo of the score card of the 3x hole in ones above?
    Hold 7 and 10 are par 4’s , there is no chance that anyone would get ones at par 4’s , let alone 2 on the same game plus another par 3.

    • Pat Mullaly says:

      Ken, you may be correct… But I’ve never played the course the writer refers to…. They may have mismarked the card??? Or there was a major miracle! Golf is a funny sport. Miracles do happen

    Yesterday was my day! The golf Gods looked down upon me and smiled! Not a long par 3 at 115 yards but it was surrounded on three sides by water. Forest Dale G.C. Salt Lake City, Utah. Number 8. Pitching wedge. My first ever Hole In One!!!!!! Ron Green
