When you're settling in to watch a golf tournament on a Sunday afternoon, the leaderboard is your guide to the action, but its language can feel like a code. Seeing a player's name with Thru 18 next to it is one of the most common terms, and understanding it is your first step to following the drama of the final round like a seasoned fan. This guide will clarify exactly what Thru 18 means, how to read all the shorthand on a golf leaderboard, and how that knowledge can make you a smarter viewer and player.
At its core, the term "Thru 18" has a very straightforward meaning: the golfer has completed all 18 holes of their current round. Their score for that day is final and will not change. You'll often see this on live, in-progress leaderboards both on TV broadcasts and online.
You might also see the letter "F" in place of "Thru 18," which stands for "Finished" or "Final." Both notations serve the exact same purpose. They signal that the player has signed their scorecard and their day is done. The reason this display is so important is that golf tournaments are fluid, not all players are on the same hole at the same time. This simple piece of information tells you whose score is set in stone and whose can still change.
The "Thru" column on a leaderboard is your real-time window into the tournament's progress. While "Thru 18" or "F" indicates a completed round, other numbers give you a snapshot of exactly where a player is on the golf course at that moment.
This information is essential for building context and suspense. A player who is leading the tournament isn't truly secure in their position until all the other contenders behind them are also "Thru 18."
Imagine this classic Sunday scenario: a fan favorite posts an incredible round of 7-under-par early in the afternoon. Their final score is -12 total for the tournament, and the leaderboard shows their status as "Thru 18." They are the "leader in the clubhouse." But the current leader, who is sitting at -13, is still on the course. Their status is "Thru 15."
This is where the excitement builds. The player on the course still has three holes left to play - the 16th, 17th, and 18th. They have a one-shot lead, but anything can happen. Will they hold on? Will they make a bogey and fall into a tie? Will they make a birdie to extend their lead?
The "Thru" notation tells you exactly how many holes remain for that drama to unfold. It’s the ticking clock of a golf tournament, and it’s why commentators get so excited about the final, difficult closing holes of a course.
To fully appreciate a leaderboard, you also need to understand the scores themselves, which are always presented relative to par.
Par is the predetermined number of strokes a highly skilled golfer should need to complete a hole. Most courses have a mix of par-3, par-4, and par-5 holes. For an entire 18-hole round, the total par is usually 72, 71, or 70. A player's score is always shown as their relation to that total par for the tournament.
If you see an "E" next to a player's name, it means their score is "Even Par." They have taken exactly as many strokes as the course par for the holes they've played. For a player who is "Thru 18" on a par-72 course, "E" means they shot a 72. An "E" signifies a solid, steady round.
This is what every golfer chases. A negative number indicates a score that is under par. A player at " -5 " is five strokes under par. Scores under par are achieved with:
The player with the most negative score (e.g., -14 is better than -12) at the end of the tournament wins.
A positive number indicates a score that is over par. A player at " +3 " is three strokes over par. These scores come from:
Sometimes you’ll see letters other than "F" or "E." Here are a few common ones:
Let's put it all together. Here is a sample leaderboard from the final round of a fictional tournament. We'll analyze it to understand the story.
POS PLAYER TO PAR TODAY THRU
----- ------------------ ---------- ---------- ------
1 Jon Rahm -14 -6 F
2 Rory McIlroy -13 -4 17
T3 Scottie Scheffler -12 -5 F
T3 Viktor Hovland -12 -3 16
5 Collin Morikawa -10 -2 F
This understanding isn't just for watching pros. It's incredibly relevant for amateur golfers, too. Many club tournaments and even friendly groups now use live-scoring apps (like Golf Genius). Friends and family can follow along from home, and you can see how you stack up against the competition in real-time.
When you're playing in a tournament, knowing who is "Thru 18" and what score they posted can change your entire strategy on your closing holes. If you see the leader is finished with a score of 75, and you are standing on the 17th tee with a current score of 73, you know you have a two-shot cushion. You can play your final holes more conservatively - aiming for the center of the greens and making bogey at worst - instead of having to fire at pins and take risky chances.
Understanding the leaderboard transforms you from a passive observer into an active insider who gets the strategy, pressure, and story of the game on a much deeper level.
In the end, "Thru 18" is more than just a piece of golf jargon, it’s a finish line. Understanding its place alongside live scoring, par-based results, and real-time updates allows you to fully engage with the suspense and strategy that make tournament golf so compelling to watch and to play.
Knowing what the leaderboard means shows you what score you need to post, but playing a smart, strategic round to achieve it is the real challenge.
