String-to-Ball Contact

The most important progressive part of any stroke or hit is the first contact of the strings of a functionally positioned tennis racket with the an exact spot on the ball (both vertically and horizontally) to functionally match the path of the racket and impart an intended action (spin) to the ball and send the ball on a predetermined flight path with consideration having been given to an intended amount of net clearance, ball flight angle, and a landing depth in the court.
