The Wedge Clock System: Partial Swings You Can Repeat

Full swings are easy to repeat because there’s a natural end point: you swing all the way back. Partial swings don’t have that. “Hit it a bit softer” means something different every time you try it. The wedge clock system fixes this by giving each partial swing a defined length, so a given wedge produces a predictable carry.

When you’ve measured your clock distances, enter them into the wedge table in the CarryMap Gap Checker to see your scoring-zone coverage.

How the clock works

Picture yourself at the centre of a clock face, viewed face-on. Your head is at 12, your feet at 6. As you swing back, your lead arm points at different hours:

• 7:30: a short swing, roughly a quarter (¼)
• 9:00: lead arm parallel to the ground, roughly half (½)
• 10:30: a longer, three-quarter swing (¾)
• Stock: your controlled stock swing, not your max

Those labels map directly to the columns in a wedge distance chart: ¼, ½, ¾ and Stock. The positions are a convention, not a law. Some players prefer 8, 9 and 10. What matters is that each position is distinct, easy to feel, and repeatable.

The key rule: change length, not speed

The clock system works because you vary only the length of the backswing and keep the tempo the same. The club should accelerate smoothly through impact on every swing.

The most common mistake with partial wedges is taking a long backswing and slowing down into the ball. Deceleration makes strike and distance unpredictable. If you notice your through-swing getting shorter than your backswing, shorten the backswing instead.

A simple check: your follow-through should be at least as long as your backswing.

Setting up for partial swings

Most coaches recommend small adjustments for partial wedge shots. The specifics vary, but common elements are:

• Narrower stance than a full swing.
• Grip down slightly for control. Choking down is also a handy extra “gear” between clock positions.
• Ball position roughly centre for a standard trajectory.
• Body rotation that matches the arm swing, so the arms aren’t doing all the work.

Keep the setup the same for every clock position, so the only variable is the length of the swing.

Measuring your clock distances

1. Warm up fully.
2. Choose a wedge and a clock position.
3. Hit several balls to a target and record the carry of each shot.
4. Use the median, so one thin or heavy strike doesn’t skew it.
5. Repeat for every wedge and every position.

With three clock positions plus a stock swing, across three or four wedges, you end up with a grid of 12–16 numbers.

Here’s how a measured set might look for one wedge:

Wedge	¼ (7:30)	½ (9:00)	¾ (10:30)	Stock
56°	34	50	66	80

Illustrative example carries in yards. Your numbers will differ.

Why “Stock” isn’t “max”

The stock wedge swing deserves its own explanation. With a wedge, a full-effort swing tends to produce more variation in launch, spin and carry than a slightly controlled swing. Many players get better distance control from a smooth stock swing that finishes in balance.

That’s why the CarryMap wedge table labels the last column “controlled stock swing, not max” and never fills it in from your full-swing number. If your controlled stock wedge carries less than your full-swing number, that’s normal. Record the shot you’ll actually hit.

Finding the holes

Sort all your clock distances across all wedges and look at the spacing. Large jumps between consecutive numbers are holes in your system. The Gap Checker does this for you and flags any jump bigger than your chosen threshold, 10 yards by default.

Ways to fill a hole:

• Choke down on the longer swing to take off a few yards.
• Add an intermediate position, such as 9:45, if you can make it repeatable.
• Adjust wedge lofts so the clubs sit more evenly. See what wedges should I carry.

Practising the system

• Block practice first: hit several shots at one position until the length feels automatic.
• Then random practice: call a yardage, choose the club and position, and hit one ball. This is closer to the course.
• Re-measure periodically. Clock distances drift as technique and equipment change.

Common problems

“My half swing goes almost as far as my three-quarter.” You’re probably adding speed on the shorter swing. Keep tempo constant.

“My distances vary a lot day to day.” Partial shots are sensitive to strike and lie. Check the setup is consistent and record medians rather than best shots.

“I can’t feel the positions.” Film yourself face-on. What feels like 9:00 is often past 10:00. Calibrate the feel to the video.

The takeaway

The wedge clock system gives every partial swing a defined length, which gives every swing a predictable carry. Keep tempo constant, measure carry honestly, treat Stock as a controlled swing, and use the results to find the holes in your scoring zone with the Gap Checker.

FAQ

Who invented the wedge clock system?

The idea of using clock-face positions to standardise partial wedge swings is widely associated with short-game coach Dave Pelz, and many coaches teach their own variations of it.

Should the follow-through match the backswing in the clock system?

Most versions keep the follow-through at least as long as the backswing so the club accelerates through impact. A shorter follow-through often means deceleration, which is the main cause of inconsistent partial shots.

Which arm do I use to read the clock?

Most systems use the lead arm, the left arm for a right-handed golfer. What matters most is that you use the same reference every time.

Can I use the clock system with any wedge?

Yes. The same swing lengths with different lofts produce different carries, which is how a few clock positions across three or four wedges create a large set of distances.
