“Ballard had made an intensive study of Ben Hogan and his “half a left arm.” It was a phrase Hogan used, as a right-handed golfer, to keep the left arm, from the top of the shoulder to the elbow, connected to the body throughout the swing. Ballard devoted his teaching life to this principle. All Ballard players—Curtis, Rocco, Sutton, Luis—make that move. They’re zealots about it.”
