The purpose served by fuzz is not minimal at all, there are many factors that are greatly affected due to this key feature.

Performance Factor:

Not just the size of tennis ball, but the fuzz or felt on the surface of the ball effectively changes the velocity and various forces acting onto it. Which is why, the speed and flight of ball is greatly affected. If you compare two same sized balls, one with fluffed up fabric and other with worn-out fuzz, you will see a huge amount of difference between their Aerodynamic drag.

Fuzzy Fabric

If you look closely the fabric on tennis ball is rough and not extremely smooth or soft. As the ball is shot through racket, it travels and air flows through the tiny raised filaments termed as fuzz. The fuzz is what allows the ball to travel farther away by precisely controlling its speed. Moreover, players can have enhanced control over the tennis ball. Whenever the tennis ball with fuzz hits the racket, it works as a grip and hence, players gain more control over the ball.

Not just that, but fuzz also helps to control the tennis ball’s flight. At higher speeds, this fuzz is what gives the slight amount of resistance to help slow down its speed. Plus, it also provides a lot of surface for effective spin.

Apart from its performance factor, the felt on the tennis ball also affects the durability.

Durability Factor:

A ball without any fuzz (regular rubber balls) might not survive as greatly as the ones that have a fair amount of fuzz do. Hard courts tend to be very rough on tennis balls of any type. The fuzz on the ball will enhance the durability so as to serve you better with time.
