Seeing a negative number like a -1 next to a golfer's name can be confusing at first, but it happily represents the primary goal in golf: to finish a hole or a round in fewer strokes than the target score. In this guide, we'll break down exactly what -1 means, how it relates to scoring, and most importantly, how you can start putting more of those coveted negative numbers on your own scorecard.

The Foundation of Golf Scoring: Understanding Par
Before we can understand what a score of -1 means, we first need to get a firm grip on the concept of "par." In golf, every single hole on the course is assigned a par number. Think of par as the expected or target number of strokes a skilled golfer should take to get the ball from the tee into the hole.
Par is determined primarily by the hole's length. Holes are generally categorized into three types:
Par 3: These are the shortest holes. The par of 3 assumes you'll hit your first shot (the tee shot) onto the green, and then take two putts to get the ball in the cup.
Par 4: These are mid-length holes. The par of 4 is based on hitting your tee shot into the fairway, your second shot onto the green (this is called a "Green in Regulation" or GIR), and then two-putting.
Par 5: These are the longest holes on the course. A par of 5 allows for three shots to reach the green (tee shot, a second shot down the fairway, and a third shot onto the green), followed by two putts.
Just as each hole has a par, so does the entire course. Most standard 18-hole golf courses are a "Par 72." This is typically made up of four par-3s, ten par-4s, and four par-5s (4x3 + 10x4 + 4x5 = 12 + 40 + 20 = 72). A golfer who shoots a round of 72 would be considered to have played "even par." Any score higher than 72 is "over par," and critically for our topic, any score lower than 72 is "under par."

Ask Caddie anything. From “what club should I use?” to “how do I play this shot?” and get instant answers.
With a solid understanding of par, the answer becomes very simple. A score of -1 means you have completed a hole in one stroke less than par. This accomplishment has a famous name: a Birdie.
Making a birdie is a fantastic achievement that signifies excellent play on a hole. Here's how it breaks down by the type of hole:
Making a score of 2 on a Par 3 hole is a birdie (-1).
Making a score of 3 on a Par 4 hole is a birdie (-1).
Making a score of 4 on a Par 5 hole is a birdie (-1).
From a coaching perspective, a birdie isn't just a number. It's the reward for executing a plan perfectly. You likely hit a great tee shot to put yourself in a good position, followed it with a precise approach shot to get the ball close to the pin on the green, and finished it off with a confident putt. It's the moment where strategy, skill, and calm nerves all come together in perfect harmony.
How to Talk About It
You’ll hear golfers talk about their -1 scores in a few ways. They might say:
"I birdied the 7th hole."
"I made a 3 on that par 4, so I was one-under for the hole."
"I was putting for birdie." (This means their next putt, if successful, would result in a birdie).
Going Deeper: Scores Beyond -1
While a -1 (birdie) is the most common under-par score, it's not the only one. Playing a hole in even fewer strokes than one-under par results in even more celebrated, and much rarer, scores.
-2: The Eagle
A score of -2 on a single hole is called an Eagle. This means you completed the hole in two strokes under par. Eagles are significantly harder to achieve than birdies and require exceptional shots.
On a Par 4, this would mean holing your tee shot or your approach shot for a score of 2. It’s most often achieved by hitting a great drive and then sinking the second shot from the fairway.
On a Par 5, an Eagle is most common. It happens when a golfer hits a long tee shot and a brilliant second shot onto the green, leaving them with just one putt for a score of 3.
-3: The Albatross (or Double Eagle)
The rarest bird of all in golf is the Albatross, sometimes called a Double Eagle in the United States. This is a score of -3 on a single hole, or three strokes under par. It is one of the most difficult feats in all of sports.
On a Par 5, an Albatross would be a score of 2. This requires an enormous tee shot followed by holing out your second shot from hundreds of yards away.
On a Par 4, it means making a hole-in-one!
Fun fact: statisticians estimate the odds of an amateur golfer making an albatross are about six million to one, so if you ever make one, you've achieved something truly remarkable.
Plan every shot like a pro

One area of slight confusion for new fans is how scores like -1 are displayed on a professional tournament leaderboard. A negative score can refer to two different things: a golfer's standing for the day, or their standing for the entire tournament.
Let's say a player is on the 5th hole, and their total score is shown as "-1". This means their cumulative score across the first five holes is one-under-par. For example, if the first five holes were all par 4s (total par of 20), a score of -1 means the golfer took a total of 19 strokes. They could have made four pars and one birdie. Their total score at the end of the round will determine their position.
You’ll notice on TV broadcasts and leaderboards, under-par scores are almost always displayed in red numbers. It’s a visual cue that the player is doing well. Scores of even par (E) are usually black or green, and over-par scores (+) are also typically black.

Hearing all this is great, but how do you actually go out and make a birdie? As a coach, I can tell you it's less about trying to hit "miracle" shots and more about a solid, repeatable process. Don't try to birdie every hole, instead, focus on good strategy to create opportunities.
1. Identify Your Birdie Holes
Before your round, look at the scorecard. Are there any short Par 4s? Maybe there's a Par 5 you know you can reach in three comfortable shots. Is there a Par 3 where the green is wide and you can confidently hit it with a mid-iron? These are your target holes. Having a plan and knowing where your best chances are removes the pressure of trying to force something on a hole that doesn't fit your game.
2. The Tee Shot is About Position, Not Just Power
One of the biggest mistakes amateur golfers make is grabbing the driver on every long hole and trying to smash it as far as possible. The goal of the tee shot isn't just distance, it's to place your ball in the best possible position for your next shot. A ball in the middle of the fairway 150 yards from the hole is infinitely better than one in the rough 120 yards away. On your target holes, pick a club that gives you confidence you'll find the fairway.
3. Master Your Approach Shot Yardages
Modern golf is a game of numbers. To make a birdie, you need to hit the green in regulation, and that means being precise with your approach shots. Spend time at the driving range figuring out how far you actually hit each of your irons - not how far you think you hit them. Don't measure your "perfect" shot, measure your average shot. Knowing with confidence that your 8-iron goes 145 yards simplifies decision-making on the course and lets you swing with conviction.
4. Become Friends with Lag Putting
Most birdie putts for amateurs will be from outside 15 feet. From that distance, your primary goal is not to "make" the putt, but to give it perfect speed. Good speed control - or lag putting - means you will nestle the ball up close to the hole, leaving an easy, stress-free tap-in for par. By taking the pressure off making the long putt, you will paradoxically free up your putting stroke, and you'll find that more of them start to fall in for those -1 scores. When your primary focus is on getting the speed right, the line often takes care of itself.
Final Thoughts
In short, seeing a -1 in golf means a player is one stroke under par, a score known as a birdie. It signifies smart strategy and solid execution, and chasing those red, negative numbers is what makes the game so challenging and rewarding.
