Wyndham Clark closed out the 2026 CJ Cup Byron Nelson with a final-round 60 — eleven under par on Sunday, including a 28 on the back nine — to overtake Si Woo Kim and Scottie Scheffler at TPC Craig Ranch. He became the first PGA Tour player ever to win twice with a closing round of 60. The headline number, though, sits on the greens: across four rounds Clark picked up more than 12.5 strokes putting, leading the field by a wide margin.
The eagle on the par-5 12th to take the lead. The 45-foot bomb for birdie at the par-3 15th. Another birdie at the stadium 17th to stretch the cushion. Every one of them rolled in off the same putter — a stock Ping Scottsdale TEC Ally Blue Onset that Clark started gaming at the Houston Open earlier in the year after a months-long search. Below: the exact 2026 specs, why the Ally Blue Onset's geometry fit Clark specifically, and what amateurs can take from his putter search.
The Sunday 60 That Capped a Five-Month Putter Search
Clark didn't arrive at TPC Craig Ranch with a settled gamer. Coming out of last year's U.S. Open disappointment at Oakmont and an inconsistent start to 2026, he spent the first months of the season testing putters. At the Players Championship in March, he was famously gaming a putter he had bought off the rack at his home club's pro shop — an unusual sight at tour level, where almost every flatstick is custom-built. It worked well enough to keep, but not to settle in with.
At the Houston Open, Clark switched to the Ping Scottsdale TEC Ally Blue Onset for its 5° of toe hang, looking to counteract his left miss. At the RBC Heritage he made one more refinement — moving to a counterbalanced version of the same head, with weight added higher in the shaft to quiet his hands through the stroke. His strokes-gained-putting numbers climbed in the first two events with it. By the time he reached Craig Ranch, the putter felt locked. Then came Sunday — and the field gave up a 60.
The takeaway from the search isn't "stock putters are fine." It's that Clark, the 2023 U.S. Open champion, was willing to keep changing until the geometry of the head actually matched his stroke. Most amateurs do the opposite — buy once based on look, then live with a mismatch for years.
Full Specs: Ping Scottsdale TEC Ally Blue Onset CB (2026)
Here are the exact specs of the putter Wyndham Clark used to win the 2026 CJ Cup Byron Nelson, per the post-round golf.com WITB report:
- Model: Ping Scottsdale TEC Ally Blue Onset CB
- Length: 38 inches
- Loft: 3°
- Lie: 70°
- Head weight: 385 grams (with 17g tip weight)
- Toe hang: 5° (mid-mallet, suited to a slight arc stroke)
- Hosel: Full-shaft offset (the "Onset" in the model name)
- Counterbalance: Yes — extra weight added higher in the shaft to slow the hands through the stroke (the variant Clark switched to at RBC Heritage)
- Insert: PEBAX (soft thermoplastic — same family Ping uses across its modern milled-face mallets)
- Grip: SuperStroke
Two things on this spec sheet matter more than the brand name. The first is 38 inches — long for a tour player. Clark is 6'3" and stands tall over the ball; the extra inch over a standard 35" off-the-rack flatstick puts his eyes and shoulders in line without him reaching down. The second is the 5° of toe hang, which is the entire reason this putter beat out the others in his testing.
Why the Ally Blue Onset's 5° Toe Hang Was the Key Detail
Toe hang is the angle at which the toe of the putter face points downward when you balance the shaft on your finger. It's a proxy for one thing: how much the face wants to rotate open and closed through the stroke. Face-balanced putters (0° toe hang) want to stay square — they reward a straight-back-straight-through stroke. High toe-hang putters (40°+, often blade designs) reward a strong arc, where the face opens going back and closes coming through.
5° puts the Ally Blue Onset in the slight-arc bucket. That's a small but specific window. Clark's stroke is closer to face-balanced than a classic blade player's, but he tends to miss left under pressure — confirmed in the Today's Golfer WITB write-up. A pure face-balanced putter exaggerates the miss because the face doesn't rotate enough to square up if his hands get quick. A high-toe-hang blade overcorrects in the other direction. The 5° toe hang is enough rotation to counter the left miss, not enough to introduce a right one — exactly the matching he was hunting for.
This is the part of putter fitting that gets skipped most often. Length, head shape, and grip get all the attention because they're visible. Toe hang is invisible until you balance the shaft on your finger — but it's what determines whether the putter wants to do what your stroke wants to do.
What Clark's Setup Teaches Amateur Golfers
Three usable lessons sit inside Clark's 2026 putter story, and none of them require buying a $500 milled putter.
1. Length first, then hang. Most amateurs play putters that are too long for their setup. The standard 35" off-the-rack length suits roughly the average male golfer at average height with average posture — which is almost nobody. If you stand tall like Clark, you may need longer. If you're shorter or break more at the waist, you almost certainly need shorter. Get the length right before worrying about insert feel or head weight, because length determines whether your eyes are over the ball at all.
2. Match toe hang to your miss, not your stroke "type." The classic instruction is "arc stroke = toe hang, straight stroke = face balanced." That's a starting point. The better question is: where does your miss go under pressure? If you push right, you want more toe hang to help the face square up. If you pull left like Clark, you want less. The miss tells you what your stroke actually does, not what you think it does.
3. Be willing to keep testing. Clark went through multiple putters in five months — including a pro-shop pickup — before settling on the Ally Blue Onset. He's the U.S. Open champion. If he was willing to keep changing, the amateur with one putter they've owned since college probably has room to find better.
Length, Loft, and Lie Decoded for Your Own Putter Fit
Clark's 38-inch, 3° loft, 70° lie spec isn't a recipe — it's a snapshot of one player. Here's how to read the numbers for yourself:
- Length determines eye position. Standard 35". Tall players or those who stand tall: 35.5"–38". Shorter players or those who break more at the waist: 33"–34". The cheap test: take your stance, drop a ball from the bridge of your nose, and see where it lands. Should land on top of your ball.
- Loft determines how the ball gets rolling off the face. 2°–4° is standard. Players who press the shaft forward at impact (de-lofting it) need more — 4°. Players who keep the shaft neutral or lean it back need less — 2°. Too little loft and the ball skids; too much and it hops.
- Lie angle determines whether the putter sole sits flat at address. 70° is standard. If the toe is up at address, your lie is too upright; if the heel is up, too flat. A lie that's off by even 2° can push your start line several feet left or right on a long putt.
If you've never been on a SAM PuttLab or had a putter fitting, the lowest-effort first step is to take video from face-on at your normal putting setup, then check eye position, shaft lean, and sole contact at address. Most fitters offer a free 20-minute session if you mention you're considering a purchase. For a deeper walk-through, our putter fitting guide covers each spec in detail.
Practice the Sunday-60 Stroke at Home
Clark's back nine on Sunday — 28 strokes, including makes from 45 feet and a stack of mid-range birdies — wasn't a hot streak so much as a stroke that finally trusted itself. The way you build that kind of trust isn't on the course. It's reps on a true, predictable surface where the only variable is you.
The two pieces of home practice that translate to tour-level pressure putting:
- Pace control. Long putts — 30 to 50 feet — are won and lost on speed, not line. A tour-grade mat that rolls at a known stimp lets you build a reliable pace template. When every 40-foot putt at home rolls 18 inches past on a good stroke, you know what 40 feet feels like — and you stop leaving lag putts 8 feet short under pressure.
- Repeating the same stroke. Tour players don't have prettier strokes than amateurs; they have more repeatable ones. Repetition only builds if the surface is consistent. Carpet is not. A true-rolling mat is.
For a structured way to work on this, our complete putting drills guide has 12 drills that map directly to the situations Clark faced on the back nine — lag from 40+, knee-knockers from 4–6 feet, and downhill testers.

The Big Takeaway: Fit Beats Brand
Wyndham Clark didn't win the CJ Cup Byron Nelson because the Ping Scottsdale TEC Ally Blue Onset is the best putter on the PGA Tour. He won because, after five months of cycling through options including a pro-shop walk-in, he found the one whose geometry — 38 inches, 5° toe hang, center-bend hosel — actually matched what his stroke wanted to do under pressure. The same logic scales down. The putter on your rack right now is almost certainly the wrong length, and probably the wrong toe hang. Fixing that won't make you shoot 60. It will make the strokes you already own behave like Clark's did on Sunday — predictable, square at impact, and trustworthy from 12 feet when the round is on the line.
