Why are tennis balls fuzzy?

Quick Answer
The felt covering slows the ball in the air, helps the racket grip it for spin, and makes its bounce more predictable.
The Full Story
A tennis ball is a pressurised rubber core covered in felt made from wool and nylon. The fuzz adds air resistance, keeping speeds manageable and rallies longer. It also lets strings bite into the ball to create topspin and slice, and it softens contact with the court. As the felt wears down, balls fly faster and bounce differently, which is why professional matches change balls regularly.
