After he won the Open they were talking specifics of his swing on the Golf Fix. Showed slow motion of how he flexes his left wrist on his backswing. Said hat this was the proper position for your backswing and showed some drills to get that bend in the wrist. Mainly with the credit card in the glove. However, I have watched slow motion on Day, Spieth, Sneds, Scott and none of them appear to have any hinge in their left wrists at the top of their back swing. Am I missing something?
