Duffspin in Table Tennis: Why the Ball Floats Long and How to Fix It
The problem: a loop that looks loaded but lands long
At a club night in Leeds, a player I’ll call Mina kept floating her forehand loop long. The stroke had arc, sound and effort, yet the ball sailed past the end line and sat up for the blocker. Her coach called the result duffspin: not a ball with no spin, but a ball whose spin is the wrong kind or too weak for the swing that produced it. The visual cue is a loop that looks heavy in the backswing but arrives flat, floaty and easy to counter.
The cause: brushing below the ball’s equator
Duffspin usually starts at contact, not in the legs. If the racket face opens at the last moment, the wrist drops under the ball, or the contact point sits too low, the rubber brushes downward instead of upward. The ball then carries backspin or weak topspin; it rises less than expected and drops short or long without bite. A common example is a player who waits for the ball to fall below table height, then tries to lift it with arm speed. The takeaway is blunt: check racket angle and contact height before adding power.
The solution: rebuild contact from the elbow
Mina’s fix was mechanical and small. She set her elbow at roughly 90 degrees, closed the racket face slightly, and met the ball at the top of the bounce. Instead of lifting with the shoulder, she brushed upward and forward, finishing near her left eyebrow. Three sets of 20 shadow swings, then 50 gentle forehands against backspin, changed the ball flight. The result was a lower, heavier arc that forced the blocker to reset. The lesson: duffspin is a contact problem, so solve it with contact constraints, not more force.
A practice set that transfers to match play
- Shadow check: do 20 slow swings with a closed racket and a visible upward brush; stop at the finish.
- Feed drill: have a partner push backspin to your forehand; loop 30 balls at 60 percent power, aiming for the middle of the table.
- Pressure game: play first-to-7 points where a long loop counts as a lost point, even if it lands in.
Score the quality of the spin, not just the result. A loop that lands on the table but carries duffspin will be attacked by better players. Once the contact point and racket angle hold under pressure, the stroke keeps its bite in matches.
