What Are R1 and Thru in Golf?

Watching a professional golf tournament can be as exciting as playing a round yourself, but deciphering the leaderboard can feel like trying to read a secret code. You see names, numbers, and a mix of letters like R1, Thru, and F - what does it all mean? This guide will translate that leaderboard lingo for you, explaining what R1 and Thru mean so you can follow the action like a seasoned pro and maybe even pick up a few strategic pointers for your own game.

Decoding the Basics: What Do R1 and Thru Mean?

Let's start with the two most common terms you'll see during a live tournament broadcast. Once you understand these, the rest of the leaderboard begins to make sense.

What Does R1 Mean on a Golf Leaderboard?

R1 simply stands for "Round 1."

Most professional golf tournaments are four-day events, typically running from Thursday to Sunday. Each day corresponds to one round of golf, which consists of 18 holes. The leaderboard uses a straightforward a_bbreviation to keep things organized:

  • R1: Round 1 (Thursday)
  • R2: Round 2 (Friday)
  • R3: Round 3 (Saturday)
  • R4: Round 4 (Sunday)

When you see a score next to a player's name with "R1," it's telling you about their performance in that specific round. For instance, if you're looking at a leaderboard on Saturday (R3) but see an old score for a player from the first day, it might be displayed next to that "R1" designator. Most often, this system is helpful for showing a player's scoring history throughout the week.

Understanding "Thru" in Golf Scoring

"Thru" tells you how many holes a player has completed in their current round.

This is one of the most important pieces of information an a live leaderboard. It gives you the real-time status of a player's round. Think of it like a progress bar.

Here’s an example: You see this on the leaderboard during Round 2 (Friday):

5. Justin Thomas -6, (Score Today: -3 Thru 9)

Let’s break this down:

  • -6: This is his total score for the entire tournament so far.
  • Score Today: -3: This is his score for just today's round.
  • Thru 9: This means he has finished playing the first nine holes of his second round.

The "Thru" status is dynamic and updates as the player completes each hole. So, when he finishes the 10th hole, it will change to "Thru 10." When he has finished all 18 holes of the day, the status will change to "F" for "Finished."

Putting It All Together: Reading a Live Leaderboard

Now that you know the basics, let's look at how all the elements work in harmony on a live leaderboard. During a broadcast, the leaderboard condenses a ton of information into a small space. Understanding it elevates your viewing experience from just watching shots to understanding the unfolding strategy and drama.

How Scores, Rounds, and "Thru" Status Work Together

Imagine it’s Saturday afternoon, during the third round of The Masters. Here’s a snapshot of a hypothetical leaderboard you might see:

POSITION | PLAYER | TOTAL SCORE | TODAY | THRU
----------------------------------------------------------------
1. Scottie Scheffler | -11 | -4 | Thru 14
2. Collin Morikawa | -9 | -2 | F
T3. Viktor Hovland | -8 | -5 | Thru 16
T3. Jon Rahm | -8 | -3 | F
5. Patrick Cantlay | -7 | E | 1:30 PM

Let's go line by line:

  • Scottie Scheffler: He's in first place with a total score of 11 under par. Today, in the third round, he's having a great day at 4 under par and has just completed the 14th hole. He still has four holes to play.
  • Collin Morikawa: He is in second place. His round is Finished (he’s back in the clubhouse), and his score today was 2 under par, bringing his tournament total to -9.
  • Viktor Hovland: He is tied for third. He is on fire today at 5 under par through 16 holes. He has two challenging holes left, so his position could change dramatically. The "T" simply stands for "Tied."
  • Jon Rahm: Also tied for third, his round is finished. His 3-under-par day puts him in a good position for the final round on Sunday.
  • Patrick Cantlay: He is currently in 5th place. Instead of a "Thru" status, you see a time: "1:30 PM." This is his tee time. It means he has not yet started his third round. His "Today" score is "E" (Even par), because he hasn't hit a shot yet.

Beyond R1 and Thru: Mastering Other Leaderboard Lingo

To become a true leaderboard wizard, you need to know a few more common abbreviations. They provide context about players who are struggling, had to leave the tournament, or are right on the edge of getting to play on the weekend.

A Glossary of Common Golf Leaderboard Abbreviations

  • F (Finished): As we covered, this means the player has completed all 18 holes for the day. Their score is locked in. Sometimes, you might see "18" instead of "F."
  • E (Even Par): This indicates a score of zero. A player who is "E" for the day has an equal number of birdies and bogeys (or has just made all pars). A total score of "E" means they are at even par for the tournament.
  • CUT (or MC for Missed Cut): Professional tournaments feature a "cut" after the second round (R2). Only the players with the top scores (e.g., top 65 and ties) advance to play the final two rounds on the weekend. Those who don't score well enough are "cut" from the tournament. You'll see "MC" next to their names on the final leaderboard.
  • Projected Cut: During the second round, you might see a "Projected Cut Line" on the leaderboard. This is a fluctuating estimate of the score needed to make the cut. Players, broadcasters, and fans watch this line closely all day Friday.
  • WD (Withdrew): This player has voluntarily withdrawn from the tournament, often due to an injury or a personal emergency. You'll see "WD" next to their name, and they are removed from the standings.
  • DQ (Disqualified): This means a player was removed from the tournament for breaking one of golf's rules, like signing an incorrect scorecard.
  • Red and Black/Blue Numbers: On most digital leaderboards, colors provide instant context. Red numbers signify an under-par score (which is good!). Black or blue numbers signify an over-par score. Even par ("E") is almost always black.

Course Management Lessons from the Leaderboard

So, why does any of this matter for an amateur golfer? Because watching how a professional's "Thru" score evolves is a masterclass in course management and mental toughness.

You might see a player start hot, going -3 Thru 5 holes. But then, as they enter a notoriously difficult stretch of the course ("Amen Corner" at Augusta, for example), their score holds steady at -3. They might go "par-par-par" for the next three holes. From the outside, that looks less exciting than making birdies. But for the player, that's a massive victory. They successfully navigated a tough section without giving any shots back.

This teaches you a valuable lesson: golf is not about trying to make a birdie on every hole. It's about capitalizing on scoring opportunities and minimizing damage on difficult holes. When you play your next round, think like a pro navigating the course. Identify the easy holes where you can be aggressive and the hard holes where making a simple par is a great achievement.

The leaderboard doesn't just show you scores, it tells the story of each player's round - a story of smart decisions, resilience, and strategic thinking that you can apply to your own game.

Final Thoughts

Reading a golf leaderboard moves from confusing to simple once you learn that R1, R2, R3, and R4 denote the four rounds, and "Thru" indicates a player's progress in their current round. Combined with a few other abbreviations like "F," "E," and "CUT," you now have all you need to follow any professional tournament.
