What Is 2 Under in Golf?

Shooting 2 under in golf is a significant achievement that signals excellent play, whether it happens on a single hole or over an entire round. Most golfers dream of scoring under par, and getting to two under is a moment to remember. This guide will break down exactly what 2 under in golf means, cover the different contexts, and give you some real, coach-approved advice on how you can start working toward that incredible score yourself.

First, A Quick Refresher on "Par"

Before we can talk about being under par, we have to be absolutely clear on what par is. You can’t understand the goal a player has achieved without first understanding the baseline they beat.

In golf, par is the predetermined number of strokes a skilled golfer should need to complete a hole. Think of it as the "expected" score.

  • Par is determined by the hole's length. Shorter holes are Par 3s, medium-length holes are Par 4s, and the longest holes are Par 5s.
  • For any par, the calculation generally assumes two putts on the green. So, on a Par 4, you're expected to take two shots to reach the green and then two putts to get the ball in the hole.

An entire golf course also has a par, which is simply the total of the pars for all 18 holes. Most standard courses are a Par 70, 71, or, most commonly, 72.

With that foundation set, let's explore what it means to be "2 under."

The Ultimate Prize: Scoring 2 Under on a Single Hole (The Eagle)

When a golfer scores 2 under par on an individual hole, it is called an Eagle. It's a rare and exhilarating accomplishment that electrifies a round of golf. An Eagle means you completed the hole in two strokes fewer than its par.

Here’s how you can make an Eagle on different types of holes:

  • On a Par 5: This is the most common way to make an eagle. It requires scoring a 3. Typically, a player achieves this with a long, powerful drive, followed by another excellent long shot (like a 3-wood or a hybrid) that lands on the green, and finishes by sinking the putt for a 3.
  • On a Par 4: To get an Eagle here, you need to score a 2. This is usually accomplished by a very long hitter who "drives the green" on a short Par 4 and then makes the putt. It’s significantly harder than an eagle on a Par 5.
  • On a Par 3: Scoring 2 under on a Par 3 means getting a hole-in-one! While a hole-in-one is its own legendary feat, it is technically an Eagle on a Par 3.

What About 3 Under on a Hole?

While we're talking about rare feats, it’s worth mentioning the even rarer cousin of the Eagle: the Albatross, or a Double Eagle. This breathtaking accomplishment is a score of 3-under-par on a single hole. It means scoring a 2 on a Par 5 (hitting a perfect drive and then holing out your second shot from the fairway) or, almost impossibly, a hole-in-one on a Par 4.

The odds of an amateur golfer making an albatross are estimated to be somewhere around 6 million to 1, making it one of the most remarkable shots in all of sports.

Great Feat of Stamina & Skill: A “2 Under” 18-Hole Round

Scoring an Eagle on one hole is an amazing feeling, but posting a final score of 2 under par for the entire 18-hole round is a mark of a truly skilled and consistent golfer.

Shooting "2 under" for the round simply means your total score at the end of 18 holes was two strokes better than the course's par. If you're playing a Par 72 course, a 2-under-par round would be a final score of 70.

A round of 2 under par is rarely a result of just making two birdies and 16 pars. Golf is a game of ups and downs, and a good score is often about balancing the good holes with the bad. A golfer shooting 70 on a Par 72 might have a scorecard that looks something like this:

  • 4 Birdies (-1 each) = You are 4 under par on those holes.
  • 12 Pars (Even par) = No strokes gained or lost.
  • 2 Bogeys (+1 each) = You are 2 over par on those holes.

The final math would be: -4 (from birdies) + 2 (from bogeys) = -2 total score relative to par.

This is what makes shooting under par for a round so impressive. It doesn’t demand a perfect round without mistakes. Instead, it demonstrates the ability to bounce back from bogeys with birdies and to manage the game well enough to produce more positive outcomes than negative ones over four-plus hours of play.

A Coach's Advice: How to Go From Surviving to Scoring

For most amateur golfers, the concept of shooting under par can feel a million miles away. You might be focused on simply breaking 100 or 90. But the strategies that lead to lower scores are essential for golfers at every level. If you want to start making progress toward becoming a player who can legitimately challenge par, here are some practical, fundamental areas to focus on.

1. Develop Bulletproof Course Management

Lowering your score isn’t always about hitting the ball better, it’s about thinking better. The number one mistake I see golfers make is poor decision-making.

  • Don’t Pull Driver Automatically: The tee box on a Par 4 or Par 5 feels like the place for the "big stick," but it isn't always the smart play. Ask yourself: "What is my goal on this tee shot?" Sometimes, the play is to use a 3-wood or a hybrid to ensure you find the fairway, avoiding that out-of-bounds stake or fairway bunker that ruins a hole. Being in the short grass for your second shot is almost always better than being 20 yards farther up in the deep rough or behind a tree.
  • Play to a "Safe Side": Look at where the trouble is around a green. Is there water left? A deep bunker right? Mentally remove that side of the hole from your target. Aim for the center, or even the "fat" part, of the green. Committing to a safe shot gives you a much better chance of making an easy two-putt par instead of bringing a double bogey into play.

2. Become a Master of the Scoring Zone (100 Yards & In)

Around 60-70% of all golf shots happen within 100 yards of the hole. This is where scores are truly made. The pros aren't necessarily that much better than you off the tee an average basis - where they truly dominate is with their wedges and putter.

  • Know Your Wedge Distances: Go to the range and figure out how far a full swing, a three-quarter swing, and a half-swing with each of your wedges fly. Write these numbers down. When you're on the course and have 85 yards to the pin, you'll know exactly which club and swing to use with confidence.
  • Make Lag Putting Your Best Friend: The key to eliminating scorecard-wrecking three-putts is solid lag putting. On long putts, your goal isn't to make it - it's to get the ball within a three-foot circle around the hole. Practice focusing only on the speed of your putts, not the line. This takes the pressure off and makes your second putt a simple tap-in. Turn three-putts into two-putts, and you'll save strokes every single round.

3. Create a Specific Plan for the Par 5s

Par 5s are the breathing room on any golf course. They are your best opportunity to score under par, yet so many amateurs play them without a clear strategy. For most players, you should approach every Par 5 as a planned three-shot hole.

  • Shot 1 (The Drive): The goal is position, not maximum distance. Hit a club that you are confident will find the fairway.
  • Shot 2 (The Layup): Do not just blast away with a 3-wood hoping to get close to the green. This is a layup shot. Your goal is to advance the ball to your absolute favorite wedge distance. Do you love hitting your sand wedge from 80-90 yards? Then hit a club that will leave you at that exact distance.
  • Shot 3 (The Approach): Now you are standing at your perfect yardage, hitting your favorite club into the green. You’ve given yourself the highest possible chance to stick it close and make that birdie putt.

By a adopting this "three-shot" mindset, you can turn a low-percentage gamble into a high-percentage birdie opportunity on a consistent basis.

Final Thoughts

Understanding "2 under" in golf celebrates two different but equally impressive feats: the single-hole brilliance of an Eagle and the sustained excellence of a complete under-par round. Achieving either represents a combination of great shot-making, smart on-course strategy, and mental toughness. It's a gold standard that shows a golfer is truly in command of their game.
