Carlos Alcaraz has joined the fight to get ATP Tour bosses to stop changing the balls used at different tournaments after he lost to Alexander Zverev on his ATP Finals debut.
Novak Djokovic admitted last month that he held talks with the sport’s governing body as a voice for the players angered by the different balls used on tour.
Alcaraz is the latest to speak out, insisting the ATP have to do something to help stop its best players suffering injuries.
He said: “They should do something, because it is incredible that in three or four tournaments in a row, each one has a different ball.
“I think each tour should have the same ball. In Australia, the same ball. In South America, the same ball. Don’t change it every tournament. I think if I’m not mistaken we have played with 20 or 21 different balls throughout the year. It is crazy.
“There are many players injured by this. If ATP wants to have the best in every tournament, they should change this or they will all be injured.”
