The ability to produce topspin on various shots — serves, drives, dinks, and volleys. Topspin creates a dipping ball flight that provides insurance the ball will drop into the court even when hit with pace, and is the primary counter to incoming backspin.
The paddle moves from low to high, brushing up the back of the ball. The wrist stays stable while the shoulder and elbow generate the upward motion. Contact is made slightly below center of the ball. The follow-through finishes high. On drives, topspin allows clearing the net by a decent margin while still having the ball drop in. On dinks, topspin curls the ball back cross-court with a combination of topspin and sidespin.
Ben Johns: instead of hitting behind the ball (flat) or inside the ball (slice/fade), hit the OUTSIDE third. This one adjustment naturally closes the paddle face AND creates topspin — they happen together automatically. "When you focus on outside of the ball, topspin just happens." Most players are told "close the paddle face" and "swing low to high" as separate cues — hitting the outside third accomplishes both in one thought.
Cincola: face angle means NOTHING in isolation. A paddle that looks "open" produces TOPSPIN if the swing path is vertical — because the face is CLOSED relative to that path. Three relationships: face square to path = flat (no spin). Face closed relative to path = topspin. Face open relative to path = backspin. Most players think about absolute face angle ("close the face for topspin") when they should think about the RELATIONSHIP between face and path.
Navratil: the pro vs amateur difference isn't technique — it's WHEN the wrist position is locked. Pros set their wrist position completely BEFORE starting forward motion. Amateurs have body and paddle motion right up until contact — the wrist isn't ready in time, producing rushed, inconsistent contact. The sequence: set wrist → lock → swing → finish with same wrist position you started.
Navratil: wrist lag — the mechanism that creates power and spin on drives and serves — should happen NATURALLY from good preparation, not from actively forcing the wrist back. Two prerequisites: (1) unit turn (entire upper body coils, non-dominant hand near paddle head), (2) correct grip pressure (2-3/10 — firm enough to hold, loose enough to allow lag). With these two things, the wrist naturally lags when you accelerate the arm forward. "You allow it, not force it."
