For those who have not played a lot of tennis, understanding how each tournament using a different kind of tennis ball and why that is an issue can be confusing. Imagine playing baseball and every week the weight of the ball is different. That can cause a player to throw the ball at different angles because the slightest difference in weight can affect how far one throws the ball and how hard they can.
The complaint about the ever-changing kind of balls at each event is nothing new, but the argument has grown louder over the last year or so. Many top players, such as Daniil Medvedev and Ons Jabeur have complained about the issue. There certainly is a correlation between different weights of the tennis balls for each tournament can cause wear and tear on wrists, elbows, and shoulders, and that wear and tear can eventually cause injuries.
This very likely could have been the case recently with ATP No. 1 Novak Djokovic. He was hampered at the United Cup by an injured wrist that was likely due to having to adapt to the weight of the ball. After losing to Australia's Alex de Minaur in the quarterfinals, Djokovic deflected talk of his injury because he did not want to take any praise for de Minaur away.
Nick Kyrgios shakes down the ATP over Novak Djokovic's wrist injury
But de Minaur's countryman, Nick Kyrgios, doesn't care so much about who he offends or what he says. Kyrgios, for better or worse, has strong opinions about many subjects and he does not mind voicing those thoughts. His wrath about the Djokovic wrist injury was directed squarely a the ATP in a tweet this week as well.
Kyrgios said, "Change of balls every week finally got to Novak's wrist...the atp really need to do something about this problem. Players suffer all the time."
And he followed that with another tweet that stated, "Also, for the people who think balls aren’t a big enough factor to result in an athlete being hurt are potato’s."
To be clear, Kyrgios is not saying the players should play with potatoes instead of tennis balls. There would surely be a weight difference there. But either way, let's hope Novak Djokovic comes back healthy before the start of the Australian Open and makes another deep run at the tournament.
