How Jon Rahm Transformed His Swing as a Junior: From Grip Adjustments to Stability

Key Points

• • Grip changes are difficult because hands are so deeply wired into motor memory from daily use (writing, eating, etc.).

   

• Changes were implemented progressively:

  • First, swings without lifting the heel

  • Then gradually added the heel lift back in stages

   

• • Jon’s left hand was made weaker and right hand repositioned to correct ball flight inconsistencies.

   

• • The original grip caused compensations in his swing path — leading to directional issues (right then left ball flight).
• • He also had an overswing as a junior — influenced by players like Anthony Kim, they shortened and compacted his backswing for more control.

   

• • Another key change: heel movement. Rahm lifted his left heel too early, so they implemented drills to keep the heel grounded longer, improving stability.
• • These changes aren’t universal — but critical for Jon at that moment (ages 13–15) to gain direction and consistency.
• • Without these adjustments, his ball flight remained compensatory — changes led to predictability and elite-level control.
• • The swing Rahm uses today was built during these junior years at Eduardo’s golf academy.
