FACE ALREADY SQUARE
Look at Xander’s clubface, clearly visible. This shows he has squared it up early; players who leave the face open would be unable to see the face at this point. Striking from the centre of a square face is a prerequisite for long hitting, and like all tour players Xander squares up very early. A great thought for you is to feel you turn the clubface away from you as you begin your downswing.
