Alexander Zverev has raised major concerns about the current quality of the tennis balls, suggesting it is negatively impacting the sport.
Germany’s Alexander Zverev has negotiated the season better than most, recently rising back to world number two. Nonetheless, he has identified a concerning dip in quality from the tennis balls used throughout the season.
On the ATP Tour, the balls used at each event vary throughout the year, with tournament organizers selecting the type of balls based on factors such as court conditions, as well as less sport-related issues like sponsorship.
However, while the constant changing of tennis balls is not necessarily a new thing players are dealing with, Zverev has highlighted that the quality of the balls is poorer.
Andy Roddick, in response to Zverev’s claims, has waded into this debate that has been circulating throughout the ATP Finals.

Andy Roddick responds to Alexander Zverev criticism over tennis balls
Zverev shared that he investigated the changes in tennis ball quality and production since the onset of the COVID-19 pandemic.
“The ball is a major concern,” he said previously, explaining that as a part of the players’ council, he had looked into it and spoke with manufacturers about the production of tennis balls.
Zverev explained that since COVID, the quality of tennis balls had significantly dropped. He mentioned that, in an effort to cut costs, companies began using different rubber materials, making the balls 30% to 60% slower than before.
He added that this issue wasn’t limited to just one company, as the balls overall had become less consistent, wore out more quickly, and performed worse.
While admitting that his season has gone rather smoothly in terms of results, he expressed concern that, in the long term, the current balls posed a real injury risk to players.
Roddick shared his thoughts after the German’s victory over Casper Ruud on Wednesday, saying: “I think he’s spot on.
“There is a lot validity in what Zverev is saying. One week it’s good and one week it’s bad. I just think the inconsistencies where maybe the tennis balls where a little bit different before week to week, whereas now I think that variance is more.”
Jim Courier also added his thoughts, explaining his players have been forced to adjust their strings and approach as a consequence of the changing balls.
“I have gleaned from Mark Knowles, who works with Jessie Pegula and also works with the players on the ATP board, and one of the things he said was talking to the stringers most players are down on their tension on average.
“That would be to get easier power from their rackets from the same swing and alleviate the burden if the balls are feeling dead or heavy.”
Countless injuries on the ATP and WTA Tour in 2024 make Zverev’s concerns interesting
The growing number of injuries on the ATP and WTA Tour in 2024 makes Zverev’s claim particularly noteworthy.
Many of these injuries have been attributed to a packed calendar, rapid surface changes, and the physical demands of the tour.
Ons Jabeur was forced to end her season early, while Elina Svitolina underwent surgery, ultimately cutting short her year for the second consecutive time.
With the calendar showing no signs of easing up – especially after Roddick criticized the two-week Masters event plans – this new issue only complicates matters further.
The relentless schedule seems to be taking its toll, and unless changes are made, player health could continue to be a major concern.
