Junior Golf Analytics: A Strokes Gained Guide

A junior golfer’s scorecard mixes two things together: how well they play and how far they hit it. For an adult those are fairly stable. For a 13-year-old, distance can change by a club or more in a single growth spurt, and a bad-looking 88 from the wrong tees may hide a very good short game. Junior golf analytics is mostly about pulling those two apart, and strokes gained is the best tool for it.

This guide is for juniors who want to track their game and for the parents and coaches helping them. It covers how strokes gained handles short hitters, which baseline to compare against, and how to keep tracking light enough that a teenager keeps doing it.

Why score to par misleads juniors

Par assumes an adult hitting adult distances. A 450-yard par 4 is a driver and a mid-iron for a scratch player. For a junior who carries driver 190 yards, the same hole is three full shots before they reach the green, so bogey is a good result, and the scorecard still marks it as a loss.

Score to par can’t tell the difference between “this kid missed every green” and “this kid hit three good shots on a hole they can’t reach.” Both show up as a 5.

Junior golf analytics: how strokes gained treats short hitters

Strokes gained, the method Mark Broadie built from PGA Tour ShotLink data, compares each shot to the expected strokes from where it started and where it finished. It doesn’t care about par. A shot that leaves you closer to holing out than the baseline expects gains strokes, even if you’re still 250 yards away.

Here’s the same junior, who drives it 200 yards, on two par 4s. These numbers use golfity’s 10-handicap baseline.

Hole A: 350 yards

Hole B: 450 yards

The bogey on Hole B still gains a third of a stroke on a 10-handicapper, because a 10-handicapper averages about 5.35 strokes from that tee. Score to par called it a dropped shot. Strokes gained calls it a solid hole with one missed 8-footer.

Look at the drive, though. The identical 200-yard drive gained strokes on the short hole and lost them on the long one. Distance doesn’t disappear from strokes gained. Most of it collects in the off-the-tee category.

Read off the tee with growth in mind

For most juniors, off the tee will be the weakest category for years. That’s expected, and it isn’t a reason to rebuild a 13-year-old’s swing in search of 15 yards. Most of that distance shows up on its own as they grow.

A better question is whether off the tee is improving from season to season on the same tees. If a junior lost 0.8 strokes per round off the tee last spring and loses 0.4 this autumn, they’ve grown or their speed has improved, and the trend says so even if they still lose that category in every round.

The categories that depend less on strength tell you more about skill right now:

• Putting. A 6-foot putt is the same length for a 12-year-old as it is for a tour player. Our 10-handicap baseline expects 1.48 strokes from 6 feet. A junior who makes those consistently can beat adult club golfers on the greens.
• Around the green. Chipping and pitching from inside 50 yards is mostly touch and technique, both of which juniors can learn early.
• Approach, measured by distance. Strokes gained judges a 160-yard shot against other 160-yard shots, so a junior hitting a 5-wood from there isn’t penalized for the club choice, only the result.

Choose a baseline the junior can beat

A PGA Tour baseline makes every category negative for nearly every junior, which is accurate and demoralizing. For most juniors, the 10- or 20-handicap baseline gives a more useful picture. Pick the one that sits a little above their current level, so some rounds come out positive. We explain the reasoning in why comparing to a 10 handicap can be better than comparing to a pro.

Move the baseline up when the junior is regularly beating it. A strong high-school player who’s beating the 10-handicap line most weeks is ready for the scratch baseline, and seeing which categories turn negative at that level shows them what to work on next.

Tees matter more than the baseline

Strokes gained adjusts for distance, but it can’t fix a course that’s far too long. When a junior plays tees where most par 4s need three full shots, almost every approach starts from 200-plus yards and the round turns into a fairway-wood exercise. The data stays accurate, but it stops showing how they’d play a normal-length course.

The USGA and PGA of America’s Tee It Forward program matches tees to driving distance, and many junior programs use their own age-based tee systems. Whichever one you follow, keep two rules:

1. Play the same tees when you compare rounds. Changing tees shifts every category, so a trend across mixed tees means little.
2. Move back when approaches get short. If the junior is mostly hitting wedges into par 4s, it’s time for the next set of tees. Expect the numbers to dip for a few rounds after the move.

Keep tracking light

The best tracking system for a teenager is one they still use in October. Logging every shot with club, lie and target is a lot to ask during a junior event, and most kids won’t keep it up.

Start with the minimum, which is where each shot finished. golfity lets you skip club selection and accuracy tracking, so a hole takes a few taps, and the shot locations alone are enough to calculate strokes gained by category.

A few habits help:

• Wait for five to ten rounds before drawing conclusions. One round of strokes gained is mostly noise, and a single bad putting day doesn’t justify changing the practice plan.
• Re-measure club distances every few months. A junior’s 150 club can change twice in a year, and stale yardages show up as approach misses that aren’t really swing problems.
• Check event rules before bringing a phone. Most junior tours allow players to keep their own stats, but conditions of competition vary, so read them first.
• Let the junior own the numbers. Parents and coaches can read the data, but a teenager who picks their own practice focus from it is more likely to keep tracking.

What a good junior stat profile looks like

There’s no single target, because a 12-year-old and a 17-year-old are effectively playing different courses. The pattern to look for is the same at every age: off the tee negative but trending up, putting and around the green at or near the baseline, and approach improving as distance arrives.

If putting is the weakest category, the junior has the most strokes available for the least physical development. If off the tee is the only negative category and it’s shrinking, they’re on track, and the rest will come with growth. Just make that call from ten rounds of data, not from one bad Saturday.
