If you've ever glanced at the tee times for the first round of a major golf tournament, you've probably noticed players are grouped in threes. This format, known as a 3-ball, is a standard and intentional part of professional golf. This article will explain exactly what a 3-ball means, the key reasons tournaments rely on this format for early rounds, and how it impacts the flow and administration of the event.

What Exactly is a 3-Ball in Golf?
In its simplest terms, a 3-ball refers to a group of three golfers playing a round together. During the first two rounds of a standard stroke play tournament, like those on the PGA Tour or DP World Tour, you'll see competitors teeing off in these groups of three.
It's important to understand the context. In this tournament setting, each of the three golfers is playing their own ball and competing individually against the entire field. Their score is theirs alone. They are not a team, and their goal is to post the best possible score over 18 holes to improve their position on the overall leaderboard. The grouping is purely for logistical and pace-of-play purposes. A 3-ball is a way to organize players on the course efficiently, not a special scoring format in itself.
You might hear amateur golfers use the term "threesome" to describe the same grouping. While both terms refer to three people playing together, in the formal world of golf rules and tournament play, "3-ball" is the precise term for the stroke play format, while a "threesome" can sometimes refer to a match play game where one player competes against a team of two.

Why Do Tournaments Use 3-Balls in Round 1 and Round 2?
Maximizing the Field and Utilizing Tee Times
Professional golf tournaments typically start with a large field, often 144 or 156 players. The first and second rounds are all about giving every single one of these golfers a chance to prove themselves and make the cut. The challenge is getting everyone through 18 holes of play within the available daylight.
To accomplish this monumental task, tournaments employ a brilliant logistical strategy: the two-tee start.
Two-Tee Start: Instead of having all groups start on the 1st hole, half of the field starts their round on hole #1 while the other half starts simultaneously on hole #10. This effectively doubles the number of groups that can be on the course at any given time, cutting the time it takes to get everyone started nearly in half.
Using 3-balls is a perfect fit for this system. Let's look at the numbers for a 156-player field:
156 players ÷ 3 players per group = 52 groups
52 groups ÷ 2 starting tees (1st and 10th) = 26 groups per tee
With tee times spaced approximately 11 minutes apart, tournament officials can get all 26 groups off each tee within about a 5-hour window. This compressed schedule is essential for completing the round before sunset, especially during seasons or in locations with shorter days. It also ensures that players in the morning wave and afternoon wave have relatively equitable course conditions, give or take changing weather.
Pace of Play: The Driving Force
Beyond simple scheduling, pace of play is a massive consideration. Anyone who plays golf knows that waiting on every shot can disrupt rhythm and make a round drag on. Now, imagine that happening in a high-stakes professional tournament broadcast live on television.
A 3-ball group is significantly faster than a 4-ball group (a foursome). Here's why:
Fewer Shots: In a stroke play group, every single player hits a shot from the tee, then the fairway, then putts on the green. A 3-ball group involves 25% fewer shots on the course than a 4-ball, which means less time spent watching others hit and waiting for your turn.
Less Time Searching: When a ball goes astray, there's one less person's ball to potentially look for.
Less Congestion on the Green: With three players reading putts and marking balls instead of four, the whole process on the green moves more smoothly.
Ultimately, a group of three can navigate the course more efficiently, which prevents frustrating back-ups from forming behind them. Maintaining a steady flow is essential not just for the players' experience but for the overall health and timely completion of the tournament day.
The "Cut" and Field Size
Rounds 1 and 2 - played on Thursday and Friday - are qualifying rounds for the weekend. The entire field is playing to "make the cut." After 36 holes, the field is reduced, typically to the top 60 players and any ties. Everyone else goes home.
Because the initial field is massive, the 3-ball system is a necessity. Once the cut happens, the situation changes dramatically, allowing for a different format.
What Happens After the Cut? The Switch to 2-Balls
Once the cut is made and Friday's round is complete, the feel of the tournament changes. The field is slashed by more than half, from 156 players down to maybe 65 or 70. With a much smaller field to manage for the weekend rounds, tournaments switch their format from 3-balls to 2-balls (twosomes).
Weekend Logistics
With fewer than half the players, there's no longer a need for the ultra-efficient two-tee start. All groups can tee off from the 1st hole. This brings a more traditional and focused flow to the weekend competition.
Creating Drama and Focus
The switch to 2-balls also serves a narrative purpose. On Saturday and Sunday, players are paired based on their score. The players at the bottom of the leaderboard tee off first, with the leaders teeing off last. This builds excitement throughout the day, culminating with the final group - the front-runners - battling it out for the championship in front of the biggest crowds and TV audiences.
Pairing the leaders in a twosome focuses the spotlight, creating a more intense, head-to-head feel even though it's still a stroke play event. This setup delivers the captivating drama that makes weekend golf so compelling to watch.

While the professional 3-ball is all about logistics, the term can mean something different in a casual round. If you find yourself in a group of three with your friends, you're not just limited to standard stroke play - there are some fantastic betting games designed specifically for three players that can add a little competitive spice to your round.
General Stroke Play
This is the most straightforward way to play in a threesome. Each person plays their own ball, keeps their own score, and you can compare totals at the end. It's often quicker than playing in a foursome and a great way to enjoy the course.
Popular 3-Player Betting Games
If you want to make things more interesting, here are a couple of classic games perfect for a 3-ball:
Nine Points (or "Nines"): On each hole, a total of 9 points are up for grabs. The points are awarded based on the net scores of the three players. The most common distribution is 5-3-1 (5 points for the best score, 3 for the middle, 1 for the worst). If there's a tie, you split the points accordingly. For example, if two players tie for the best score, they would each get 4 points (5+3=8, 8/2=4) and the third player gets 1. You tally all the points at the end of the round.
Split Sixes: This works similarly to Nines, but with 6 points available per hole. The distribution can vary, but a popular method is 4-1-1 (4 for the winner, 1 each for the other two). If there's a two-way tie for the low score, it's typically split 3-3-0. A three-way tie means everyone gets 2 points (2-2-2). This game keeps everyone involved, as even saving a tie for second place earns you a valuable point.
