ATP takes action on tennis balls as players search for solution to growing injury concerns

Saturday, 18 July 2026 at 01:00

The tennis ball has become one of the sport’s biggest talking points in recent years — not because of how it changes matches, but because players increasingly believe it is affecting their bodies.

According to Punto de Break, the ATP is testing a new measure on the Challenger Tour that could eventually reach the main circuit: replacing balls more frequently during matches in an attempt to reduce the physical impact caused by worn-out balls.

Under the current system, the first ball change normally happens after the seventh game, with further changes every nine games. In the tournaments included in the trial, those intervals will be shortened, with the first replacement coming after the fifth game and the following changes every seven games.

The idea is simple: keep the balls closer to their original condition for longer. As balls lose pressure and become heavier during play, players often need to generate more force to produce the same speed and spin, increasing the stress placed on the wrist, elbow, forearm and shoulder.

A problem repeatedly linked to injuries

The debate around tennis balls has intensified as several top players have dealt with arm-related injuries in recent seasons.

Carlos Alcaraz missed the 2026 French Open and Wimbledon after suffering a wrist injury, while Jack Draper has also managed physical issues involving his arm during his rise through the ATP rankings. Taylor Fritz has dealt with forearm problems in the last few months, showing how demanding modern tennis has become on players’ upper limbs.

Players have repeatedly pointed toward ball changes as one of the factors behind these problems. Novak Djokovic recently explained that he believes the characteristics of tennis balls changed after the COVID-19 pandemic because of modifications in manufacturing processes.

“Everyone agrees that since COVID, something has changed,” Djokovic said. “The production and manufacturing facilities in China that are used by practically all the major ball manufacturers we use on tour have changed.”

The bigger challenge: consistency across the calendar

The Challenger experiment is only one part of the ATP’s attempt to address the issue. In 2025, the organisation also moved toward centralising the process of selecting ball suppliers, after years in which tournaments independently chose different manufacturers.

For many players, however, the ideal solution would be greater uniformity across the entire season. Carlos Alcaraz previously suggested using the same ball throughout the calendar as the best possible scenario, although he acknowledged the difficulty of implementing such a change.

“The only thing I would change is playing all tournaments all year with the same ball,” Alcaraz said. “Now you have to adapt your game because every tournament has a different ball.”

The results of the Challenger trial will determine whether the measure expands to ATP tournaments. While faster ball changes could help reduce one aspect of the problem, the wider debate remains unresolved: how can tennis protect players physically while maintaining the different identities of tournaments around the world?
