It’s a sound every golfer recognizes: the sharp, plastic-on-plastic clack of your perfectly struck ball hitting another player’s ball. Whether it’s an amazing approach shot that cannons off your buddy’s ball and into a bunker or a delicate putt that gets knocked offline, the result is often chaos and confusion. This article will clear up that confusion for good. We’ll walk through exactly what to do in every situation, covering the different rulings in stroke play and match play, both on and off the green.

First, Understand the Playing Format: Match Play vs. Stroke Play
Before we can figure out what to do, you first have to know what kind of game you’re playing. The rules for hitting another ball are fundamentally different depending on whether you’re in a stroke play competition or a match play competition. This is the single most important factor.
Stroke Play: This is the most common format. You're counting every single shot, and your goal is to post the lowest total score for the round. You are, in essence, competing against everyone on the scorecard, even if they're in a different group.
Match Play: This is a head-to-head competition where you play against one opponent. Instead of total score, you compete to win individual holes. If you shoot a 4 and your opponent shoots a 5, you win the hole. The total number of strokes doesn’t matter beyond winning or losing that specific hole.
Once you know the format, figuring out the right ruling becomes much simpler. Let's break down the most common scenarios you'll face on the course.
Scenario 1: Stroke Play – Your Ball in Motion Hits another Ball (Anywhere EXCEPT the Putting Green)
This is the scenario that happens most often. You hit a drive, an approach shot, or a chip from off the green, and your ball accidentally strikes a fellow competitor's ball that is at rest somewhere on the course.
The Ruling: It’s a classic “rub of the green.” There is no penalty.
Here’s the step-by-step breakdown based on the rules (specifically Rule 11.1):
Player Who Hit the Shot (You): You must accept the result. Even if your great shot caromed off their ball and into a terrible lie, you have to play your ball from where it came to rest. Conversely, if you get a lucky bounce toward the hole, that's your good fortune. No penalty is applied.
Player Whose Ball Was Hit: This person gets to put things right. They must replace their ball to its original spot (if they know the exact spot) or to its estimated original spot (if they're not 100% sure). There is no penalty for their ball being moved.
A Relatable Example
Imagine you and your friend Mark are playing in the Saturday stroke play tournament. You both hit your drives down the fairway. Mark’s ball is 150 yards out, and yours is 160. You hit your approach shot first, a beautifully high iron that lands on the fairway right next to Mark's ball and then taps it, moving it a few feet to the right. Here's what happens:
Your ball comes to rest five feet from where it knocked his. You walk up and play your third shot from this new position. No penalty.
Mark identifies the small divot or blade of grass where his ball originally was. He picks up his ball and places it back on that original spot. He gets no penalty and plays his shot as planned.
Essentially, outside of the putting green, an accidental collision is just considered a part of the game.

Scenario 2: Stroke Play – Your Putt Hits another Ball on the Putting Green
This is where things get serious, and a great putt can turn into a disaster on the scorecard if you’re not prepared. If you make a stroke from the putting green and your ball hits another ball that was also resting on the green, the situation changes dramatically.
The Ruling: You receive a two-stroke penalty.
Here’s the correct procedure in this unfortunate situation:
Player Who Hit the Putt (You): You get a two-stroke penalty added to your score. After that, you play your ball from wherever it stopped moving.
Player Whose Ball Was Hit: Just like the previous scenario, this player replaces their ball on its original spot without penalty.
Why the Penalty? And How to Avoid It
The rules become stricter on the putting green to maintain fairness. It prevents a player from carelessly (or intentionally) using another player’s ball as a “backstop” to stop their putt near the hole. Knowing this harsh penalty exists encourages golfers to practice proper etiquette.
Fortunately, avoiding this penalty is incredibly easy:
Always ask to have balls marked. Before you putt, take a look around. If any other balls are on or near your intended line, or anywhere you think your ball might end up if you hit it too hard, simply ask your playing partners, "Would you mind marking that?"
Mark your own ball. Be a good partner. When it's not your turn to putt, be proactive and mark your ball without even waiting to be asked. It shows you know the rules and respect your fellow players' game. It's a simple act of a few seconds that can save someone two strokes.
Scenario 3: Match Play – Your Ball Hits Your Opponent's Ball (Anywhere on the Course)
Match play keeps things much, much simpler. The spirit of the format is direct competition, and "rub of the green" plays a much larger role. If you are playing match play against an opponent and your ball hits theirs, the rule is the same no matter where you are on the course - from the tee box to the fairway to the putting green.
The Ruling: There is absolutely no penalty to either player.
This is a strange one for people used to stroke play, but in a match, here's what happens:
Player Who Hit the Shot (You): You have a choice. You can either play the ball from where it came to rest, or you have the option to cancel the stroke and play again from the original spot. This is almost never done, as usually whatever happened is what happened, but the option is there.
Player Whose Ball Was Hit (Your Opponent): They must replace their ball to its original or estimated spot. No penalty.
So, if you’re on the green in a tight match and your lag putt trickles toward the hole, taps your opponent’s ball, and stops two inches from the cup... that's just fantastic luck for you! You’ll have a tap-in for the win, and your opponent will simply replace their ball. There is no penalty, even on the green. This simple, penalty-free process is one of the things that makes match play so exciting and different.

Knowing the rules is one thing, but being a great playing partner is another. How you physically handle these situations on the course says a lot about you as a golfer.
Communicate Clearly: Always be proactive. If someone's ball is a potential issue, just ask them to mark it politely. It benefits everyone.
Apologize, Even if It's Not Your Fault: It’s just good sportsmanship. If you hit someone's ball, a simple "Sorry about that!" goes a long way. Have a small laugh about the bad (or good) luck and move on.
Help Find the Spot: If you knock someone's ball, help them locate the original spot. Often, the person who hit the second ball has a better view of the collision than the person whose ball got moved.
Don't Be Shy: When your ball is on the green, be quick to mark it. Don't make others ask. This single habit will make you a favorite playing partner anywhere you go.
At the end of the day, an accidental golf ball collision is a normal part of the game. Now you know exactly how to handle it with the confidence and class of a seasoned player.
Final Thoughts
The rules for a golf ball hitting another can seem confusing, but they boil down to a few key points: what format you’re playing, and whether you are on the putting green. Understanding these distinctions keeps the game fair and fun, and handling these situations with a cool head and good sportsmanship is the best play you can make.
