What actually happened when Tom Kim showed up
Most of us on tour have seen kids come in flashy. Swing fast, talk loud, make top-10s in their first three events. Then they hit the wall and quietly vanish. Tom Kim did not do that. He came in with a swing that looked wrong from every angle, won almost immediately, and created confusion among coaches and statisticians alike. Here is the core of it. The modern game spent fifteen years optimizing for speed, center-line strikes, and launch conditions that looked identical across the field. Tour instructors built entire programs around replicating a model swing. Kim's swing does not match that model. It is short, compact, and has a grip orientation that makes most swing coaches reach for the textbook within five seconds. Yet he wins. That is the paradox. I spent the first round of his 2022 Sony Open watching him from the range. Not because he was doing anything extraordinary visually, but because everything about his setup looked like it would produce inconsistency. His left wrist was too bent at address. His hands sat too far behind the ball on the backswing. Most players with that configuration miss fat or thin every third shot. Kim missed nothing.
The reason is not some hidden talent. It is timing and release mechanics that most people overlook because the input looks abnormal. His tempo ratio sits around 3:1, which is actually above the tour average. That slow takeaway is not a quirk. It is the primary stabilizer that lets him return the clubface squarely despite the non-standard grip and wrist position. Without that specific tempo, his setup fails. With it, it works consistently under pressure. When I ran his numbers through TrackMan for comparison against tour average, the shot shapes told the story. He hits 6-iron wedge distance numbers with a 7-iron. His spin rates run 200 to 300 RPM lower than model expectations for his clubhead speed. That means he is not fighting the ball. He is using a release that minimizes side spin without sacrificing control. Most instructors would call that a defect. It is his actual advantage. I tried coaching a junior player to replicate Kim's setup after watching him win in Hawaii. We made it through a week before the kid started shanking fairway woods off the tee. The problem is not the setup. The problem is the transition speed required to make it functional. If your downswing transition is faster than Kim's, his wrist angle snaps open and you lose the face control. I had to drop the idea entirely and instead teach the kid a more conventional position that produced 85 percent of the same result. That is the trap most people fall into when they study Kim's swing.
The deeper insight is that Kim is not actually playing a different sport. He is exploiting a gap that modern teaching created. When everyone optimizes for the same launch window and the same positive dynamic loft, the margins for error shrink. You need a swing that produces consistent contact even when conditions change. Kim's swing is less sensitive to minor path variations because of how his release works. It is not faster. It is more forgiving. This matters for the game at large. You are now seeing instructors add anti-clock face closure drills to their curriculum for the first time since the mid-2000s. Not because it is trendy, but because Kim proved that a certain type of release can coexist with low spin and high accuracy. That combination was considered theoretical five years ago. Now it is being tested on range balls every day. There are limits to this approach. It does not work well for players who need trajectory control in wind because Kim's release naturally produces a lower ball flight. I have seen it fail on coastal courses where you need to hold greens with long irons in 20-mile-an-hour crosswinds. If your game relies on high spinnable approach shots, this model is not for you. Stick to conventional positioning.

Also worth noting: this style requires a very specific type of wrist flexibility. Players with stiff wrists or previousgolfer's elbow tend to break down quickly when they try to adopt a similar setup. I worked with a player who forced his wrists into Kim's position and developed tendonitis within six weeks. We returned him to a neutral grip and rebuilt his transition speed instead. That took fourteen months. Not worth the risk unless you have healthy connective tissue and the patience to rewire a swing. If you want to understand this without standing on a range with a rangefinder, watch the 2022 Masters second round. His iron play on holes four through eight shows exactly how the compact swing handles firm lies. The divots are shallow and short. That is not a flaw. It is the intended outcome of his release path. Most players would dig a full divot here and send the ball 12 feet over the green. Kim keeps it on the target line. The broader implication for the game is already visible. Equipment companies are adjusting loft and lie specs because Kim's setup changes how the club interacts with the ground. Clubs that used to sit square to the address position now need slight modifications for players who adopt a similar technique. This is not speculation. I saw three major brands quietly update their fitting guides after his major win.
For amateurs, the takeaway is straightforward. Stop chasing swing speed modeled on tour pros who look identical. Look at efficiency of contact and release timing instead. Kim's swing is not meant to be copied. It is meant to prove that the old assumptions about how a swing should look are outdated. The data supports his method. The visual language of teaching has not caught up yet.
