Both Irv Schloss and Bernard Cooke (who took the four photographs above) would have loved the quality of the Morikawa impact. The winding of the left forearm, and the arched left wrist were two of the most important aspects the two top teachers looked for in a great swing.
The following is a short text from Irv Schloss describing the superstar contact:
"The right wrist is virtually extended at impact while the left wrist is still flexed. The face of the club head is square to the line of flight, being "held against the ball." The left wrist is arched up.
Pablo Larrazabal shows why he strikes the ball so well
This is a late-release position much to be desired. It is the position that separates the superstars from the rest of the golf pack.
In this release, the wrists do not hinge. Instead, they go from adducted to abducted."
