If Wyndham Clark and Si Woo Kim’s final nine at the CJ Cup Byron Nelson were a boxing match it would go down as an instant classic. The pair traded the golf equivalent of body blows, with the lead seesawing between them until Clark grabbed it for good with a birdie at the par-4 14th then dropped a 45-foot bomb at the next, providing the winning margin before Clark unleashed a closiing flurry.

The fun started with Clark birdieing the 11th to tie for the lead and Kim responding on the same hole. At the par-5 12th Clark hit a 4-iron from 246 yards to 16 feet and dropped the eagle putt to go from one behind to one in front. Kim responded with a birdie to tie before Clark’s back-to-back birdies provided separation.

The long and short end of the bag fueled Clark’s win—his first since the weather-shortened 2024 AT&T Pebble Beach Pro-Am. Off the tee, Clark ranked sixth in strokes gained/off the tee with his 10.5-degree TaylorMade Qi4D with a Project X Titan Yellow 60TX shaft.

It was on the greens, however, where Clark surprisingly shined. Coming into the event ranked 132nd in strokes gained/putting (and in negative territory to boot), the 2023 U.S. Open champ was a terror with his Ping Scottsdale Tec Ally Blue Onset mallet putter, a club he put in play at the Masters after going through multiple putters in the first few months of the season. Clark’s putter has several strips of lead tape on the bottom of the sole to counterbalance the weight of his long, oversize Superstroke Revl Mid F/C grip. The 38-inch putter has 3 degrees of loft, 20-degree lie angle and an estimated head weight of 400 grams.

These mallets look to steady your stroke with multiple onset versions that match the shaft and the center of gravity. They also attempt to steady your mind with calming alignment features that promote confident aim. The two onset models (Ally Blue, Ketsch) feature shaft positions back from the face but just in front of the center of gravity, which encourages pulling the putter through the hitting area instead of pushing it for a consistent stroke. The goal is to provide the feel of putting with a blade with the aim and stability of a mallet. The alignment aid features a long line and a single dot. It’s a result of eye-tracking research that shows that combining a line and a focal point calms the vision right before the start of the putting stroke. A third model (Hayden) uses a face-balanced heel-shafted orientation to promote a cleaner view of the alignment aid and a straight-back, straight-through stroke. The lightweight aluminum construction saves mass that’s redistributed in a steel sole plate that lowers the center of gravity and adds perimeter weighting for improved consistency on off-center hits. The face insert uses Pebax, a soft but resilient elastomer developed for the soles of athletic shoes. It mixes a softer feel with good energy transfer for consistent distance control. Top 5 in Sound/Feel, middle-handicaps Models: Ally Blue Onset, Hayden, Ketsch Onset. Head weights: 350 (Ketsch), 360 (Hayden), 370 grams (Ally Blue Onset). Lengths: 35, 38 inches. Loft: 3 degrees

The numbers were eye-popping: 13 putts made over 10 feet for the week; first in strokes gained/putting, picking up 12.565 shots on the field; first in feet of putts made at 112 per round, including 158 feet in the final round, and first in putts per green in regulation.

On Sunday that produced an 11-under-par 60, a final-nine 28—and a knockout blow resulting in a fourth PGA Tour title.
