Question

Why do you need a new can of tennis balls when you have a tennis match?

Answer 1

canned tennis balls are better than the ones newly picked...fresh from the trees...or vines...

Answer 2

Most people start a match with new balls. The pros play them for 7 games, then change to new balls every 9 games.

Balls do lose pressure and bounce after a while, although for most recreational match players, playing 3 or 4 sets with the same balls is fine.

If you lived in Europe, where balls cost $10.00 a can, you might play a little longer with the same balls.

Answer 3

so this way the balls have more spring and are more bouncy... better quality

Answer 4

newer balls bounce higher and it means its always the highest quality possible.

However this is only true for pro matches, regular matches at your local tennisc lub do not tend to always use a new set of balls each game

Answer 5

The more advanced you get, the more you will notice a difference between new balls and old balls (even those that have only one match on them).   New balls have good pressure (you can't squeeze them as easily), which gives them more bounce.  If you drop a old ball, it won't bounce very high, because its flat.  Players who like to hit with spin like new balls, because they spin better.  The new fuzz on the ball makes it easier for the tennis strings to grip and spin during contact.  The new balls are also cleaner and brighter, making them easier to see.   All these things add up, and you don't have to be a pro to appreciate new balls.  The more matches you play, the more you will see, that you just play better with new balls.

Answer 6

Old ones are worn, do not have the bounce as new ones.

Answer 7

Just like in the professional tour, they use new balls because the used ones tend to lose the bounce and the fluffiness of the ball.

Answer 8

The tennis balls bounce higher. It makes everything as fair as possible.
