[O.B.Left]

I've always struggled with uncocking my left wrist too early, and the more I try to hold that power accumulator 2 angle the tighter my left arm becomes. Any suggestions?
Thanks

These are all good suggestions.

Have you tried the Aiming Point procedure? You'll notice you dont Release Early when there is no ball there but in the presence of the ball we tend to throw the club early for some reason. The aiming point replaces the ball, your not looking at the ball anymore. Try an aiming point a few inches on the target side of the ball with a mid iron and see what happens.
