The Convex Swing System is designed for one purpose: to transfer energy perfectly. Its secret lies in the rotational follow-through, a movement imported from sports like shot put and discus. This rotation, pivoting on the left heel, drives the body forward with maximum force. You see the proof at impact: the right knee is level with the left, showing a complete, efficient transfer of energy.
YT Siew’s impact position is more compact and connected; it promotes rotational movement. It presents a sharp contrast to that of Scheffler.
Scheffler’s left foot set at 20 degrees at the address blocks the momentum of his downswing. At impact, his right knee is nowhere near his left; he has not transferred all the available energy to the ball. Consequently, he strikes the ball with a concave bend shaft.
YT’s efficient pivot fan-slide allows for the ‘convex to straight’ shaft strike on the ball at impact; the energy flows into the ball without being lost to a recoiling shaft, a concave bend shaft.
THE CONVEX STRIKE CAN DELIVER SCHEFFLER’S IMMENSE POWER
Now, look at this. Scottie Scheffler, on a downslope at the 2022 Masters. The momentum of his swing was so powerful, it caused a natural ‘walk-through’, with his right leg crossing over the left.
This was not a mistake; it was a glimpse of untapped potential. Scottie’s body naturally sought a full rotational finish when the conditions allowed it. He already possesses the athleticism and power to do this.
The difference is intention. For YT Siew, it’s by design. For Scottie, it was by accident.
So, the question is: what happens if Scottie Scheffler masters this “rotational follow-through” movement on level ground? By design? By adopting the Convex Swing System.
THE 45/90 CONVEX PRINCIPLES: FROM QUIRK TO SIGNATURE POWER MOVE
By designing his swing around the 45/90 Convex Swing principles—the stable left heel pivot and the intentional pivot fan-slide—the rotational followthrough becomes his new trademark. It would replace the need for his current ‘quirky’ balancing move with a finish of pure, powerful flow.
The result? He would achieve the pure Convex Strike—the same efficient impact as the Iron Byron machine. This isn’t just about style. It’s about channeling his immense power more efficiently.
This could add 20-30 yards to his already enormous drives, turning his power from a strength into an unstoppable force.
By adopting the Convex Swing to achieve the Convex Strike, Scottie Scheffler wouldn’t just improve; he would truly transform the game. He would become the first human golfer to do the Convex Strike. And make history!
And the Convex Swing would become commonplace.
