Note that side spin in tennis causes the ball to curve left or right while traveling thru the air (due to a Magnus force). However, this type of spin has no effect on the bounce of the ball. Spiral spin, on the other hand, does not produce a Magnus force and does not cause a left/right deviation in the flight of the ball. In fact, it tends to minimize a left/right deflection. Spiral spin will cause the ball to bounce off to the left or the right.
With spiral spin the rotation is all perpendicular to the path. This means that no part of the ball is special with spiral and hence it flies as if there was no spin. The spiral spin will only act when the ball hits the ground.
Okay, so I recently posted a thread asking how to hit sidespin. Sorry for posting practically the same thing again, but I now realize what I actually wanted to learn was spiral spin.
Can anybody tell me how to hit spiral spin when returning balls that have lots of pace (such as serves)? When hitting with my 7-year old brother, I was able to produce spiral spin, because every ball he hit was flat, and very slow, but I don't know how to replicate this when I hit a ball that is traveling rapidly toward me, or a ball that has topspin or backspin on it, etc.
Can anybody help me hit spiral spin?
