If you are wondering how often to replace tennis balls, at what point in the match or tournament they are changed, or the importance of new tennis balls when competing, then keep reading.

Why are new tennis balls used? When are they changed?

Without a new tennis ball, the game becomes much harder to play. Balls cannot travel as far or as fast as they can, which can impact the game. Not only could this cause poor play, but it may also lead to injury.

Players may attempt to overcompensate by swinging harder. Swinging harder can lead to stress on your joints. This is why players bring at least six tennis balls (two cans) to a match.

A player begins the match with a new ball, changing the ball after the first seven games. After that, the player changes their ball every nine games.

How often do they change the tennis balls in a match and why do they do it?

With time and use, tennis balls wear down and their performance decreases. We refer to those tennis balls as “dead,” meaning they’re no longer suitable for playing tennis.

A player begins a match with a new tennis ball. Players start with a fresh ball, so they do not have to swing as hard and aim better. Players will replace their balls after the first seven games and then every nine games.

Why new tennis balls are a must-have for matches

Any tennis player, whatever their level, needs new tennis balls. If you use old balls, then your game will be sluggish and tiring. If you are trying to save money, you can collect the old balls you use during a match and practice with them. That way, you save the new balls for matches.

For pros, the importance of new tennis balls all comes down to hair. The hair on a new tennis ball is smooth. The hair on an older tennis ball is fluffy. Tennis players can check up to 3+ balls before serving. That way, they can choose one smooth ball and one fluffy ball.

Pros use the smooth ball for the first serve. The hairs on the ball are flat, so the ball travels faster. That makes it harder for their competitors to return the ball. If the first serve misses, the player will use the fluffy ball for the second serve. Fluffy balls move slower but are easier to control.


Do tennis pros practice with new balls?

Pro tennis players are rough on their tennis balls. They hit the ball hard and like their balls to be in like-new condition.

After that, they change it every nine games.
