Can I Change My Golf Ball on the Green?

Standing over a pivotal putt, you notice your ball has a nasty scuff from an unlucky collision with a paved trail. Suddenly, that thin, white line you meticulously drew on the ball is jagged and unreliable. The question hits you: can you switch it out for a pristine, perfectly balanced one before you stroke the most important putt of the day? This might be one of the most common rules questions in all of golf, and the answer involves more nuance than a simple yes or no. In this guide, we'll walk you through exactly when and how you can change your golf ball on the green, the critical situations where you can’t, and what the rules say about swapping it out anywhere else on the course.

The Green Gives You Special Privileges: Understanding Rule 6.3

First things first, it's vital to know that the putting green is a special area governed by its own unique set of rules that grant you certain freedoms. Unlike when your ball is in the fairway, the rough, or a bunker, once your ball comes to rest on the putting green, you are allowed to lift and clean it. This is covered under Rule 13.1b of the Rules of Golf.

This privilege is the foundation for everything that follows. The core principle you must always remember is to mark the spot of your ball before you ever touch or lift it. By placing a coin, tee, or a dedicated ball-marker directly behind your ball, you’ve preserved its original location, allowing you to lift it for cleaning without penalty. This simple act unlocks the ability to then consider replacing it entirely.

The Answer You’re Looking For: Yes, You Can Change Your Ball on the Green

Let's get straight to the point: In the vast majority of your golf rounds - from a casual afternoon nine to your regular weekend game - you absolutely have the right to change your golf ball on the putting green a an when you like!

The permission comes from Rule 6.3b, which discusses substitution of a ball. The rule clearly states that when a player is lifting their ball (which, as we know, is permitted on the green), they can replace the original ball with another ball. It’s that simple. Once you've marked your ball on the green and lifted it, you are free to swap it out for a different one.

Why would a golfer want to do this? There are several practical reasons:

• Damage: The most common reason is damage. A ball that has hit a cart path, a tree, or a rock may have a cut or a significant scuff, which can affect its roll and performance on the green.
-

While you can clean your ball, sometimes a stubborn piece of mud or a chemical stain from course treatment won’t come off, and you’d prefer a perfectly clean surface for your putt. -

Many golfers practice a "two-ball" strategy. They might use a firmer ball optimized for distance off the tee and a softer, higher-spinning ball around the greens for better feel and control when putting. Once they reach the green, they swap their distance ball for their "putting" ball. -

Perhaps your original ball’s alignment line has worn off, or you simply set it down poorly off the tee. On the green, you can switch to a ball with a fresh, bold line to help you aim your putt more precisely.

How to Change Your Ball on the Green Like a Pro: A Step-by-Step Guide

To avoid any penalties and follow proper etiquette, it’s best to perform the substitution in a clear, methodical way. Following these steps ensures you’re always in compliance with the rules.

Step 1: Mark the Position of Your Ball

Before you do anything else, you must mark your ball. Place a ball-marker (like a coin or flat disc) directly behind or to the side of your ball. Do not touch or move the ball until the marker is securely on the ground. This preserves the exact spot where your ball must be replaced.

Step 2: Lift Your Original Ball

Once the marker is down, you can pick up your original golf ball. You can clean it and put it in your pocket if you wish. This is the moment of substitution.

Step 3: Choose Your Replacement Ball

Take your new ball out of your bag or pocket. There are no restrictions on what brand or type of ball you can switch to, unless a specific local rule is in effect (more on that below). This is your chance to put that scuffed ball away and bring out a fresh one.

Step 4: Place the New Ball on the Original Spot

Carefully place the new ball on the ground on the exact spot where you lifted the original from. You must place it, not drop it. Be precise. Placing it in front of your marker is the standard procedure. It cannot be placed closer to the hole or in an improved position on the green. This step is about replacing, not improving your location.

Step 5: Remove Your Marker

After your new ball is placed and is at rest, you can then pick up your ball-marker. It’s important to remove the marker before you make your stroke. If you putt and your ball (or another player's ball) hits your marker, it can result in a penalty.

The Major Exception: Know About the “One-Ball Rule” (Model Local Rule G-4)

Now for the single most important exception every serious golfer needs to understand: the Model Local Rule G-4, more commonly known as the "One-Ball Rule."

When this Local Rule is in effect for a competition, a player is required to play the entire round with the exact same brand and model of golf ball they started with. For example, if you start the first hole with a Titleist ProV1, you must use a Titleist ProV1 for every single stroke you make that day.

So, does this mean you can’t change balls on the green? Not quite. Even when the One-Ball Rule is active, you can still substitute a ball on the green, but the replacement ball must be the exact same brand and model. You can swap out a scuffed Titleist ProV1 for a fresh Titleist ProV1, but you cannot swap it for a Callaway Chrome Soft.

The purpose of this rule is to prevent players from strategically using different types of balls for different shots - like a low-spin distance ball for driving and a high-spin control ball for putting. It ensures a more consistent test of skill.

Who does this affect? Luckily for most golfers, the One-Ball Rule is almost exclusively used in elite competitions: professional tours (PGA Tour, LPGA Tour, etc.), high-level amateur championships, and some major club championships. It is extremely unlikely to be in effect during your weekly league play, a charity scramble, or a casual round with friends. However, if you are playing in a competitive tournament, always check the official rule sheet or ask a committee member beforehand.

What About Swapping a Ball in the Fairway or Rough?

The freedom you have on the putting green is unique. Elsewhere on the course - what the rules call the "general area" - a different standard applies. Rule 6.3a states that you must hole out with the ball you played from the teeing area, unless a specific rule allows you to substitute it.

You cannot simply decide to change your ball in the fairway because you don't like its lie or want a different type of ball for your approach shot. Substitution is only permitted in specific situations, such as:

• When Taking Relief: Whether it's paid or free relief from a penalty area, an unplayable lie, an abnormal course condition (like temporary water or a cart path), you are allowed to substitute a ball.
• When Your Ball is Severely Damaged: If your ball becomes cut, cracked, or out of shape during the play of a hole, you can replace it. However, a simple scratch or paint scuff does not qualify as "cut or cracked." The damage must be significant, and you should announce your intent to your playing partners or a marker before lifting it.
-

If your ball is lost or out of bounds and you are proceeding under stroke and distance, you will be using a new ball.

What’s the Penalty for Getting It Wrong?

The Rules of Golf are in place to ensure fairness, and breaking them comes with consequences. If you improperly substitute a ball - for instance, changing it in the fairway without permission or violating the One-Ball Rule in a competition - you have played a "wrong ball."

The penalty for this breach of Rule 6.3 is the General Penalty: - In Stroke Play, you get a two-stroke penalty. - In Match Play, you lose the hole.

Additionally, you must correct your mistake by playing out the hole with the correct ball. Failing to do so can lead to disqualification. This is why knowing when and how you can switch your ball is so Caddie.
