Hi, my name is Lincoln Ward. I’m a USPTA teaching
pro, also the director of the Austin Tennis Center here in Austin, Texas. Today we’re
going to talk about the tennis ball. Tennis ball comes in a wide variety of manufacturers
but they all have a standardized size, weight and pressure. A tennis ball pretty much consists
of a felt cover, could be a variety of different colors, a adhesive undercoat, followed by
a rubber base and every tennis ball is pressurized to about twelve pounds per square inch just
a little bit more than what is outside. That helps to increase the playability and the
bounce of the ball. Now depending on what surface you decide to play on, you might choose
to do a extra duty, a heavy duty felt, for say hard courts such as this. If you’re going
to play on the clay or grass, you’re going to want to use a regular felt. Now higher
altitude playing you can use a ball that’s a little more pressurized or completely pressureless.
But if you’re going to play a tournament with a pressureless ball, you want it acclimate
to the altitude for about 60 days prior to the play. The inside of a tennis ball as you
can see is completely empty. That’s where it’s going to be pressurized. That’s a little
bit about tennis balls.
