The ATP has launched a Challenger-level trial to reduce injuries: balls will be changed every 5 games instead of 7 on the first change, and every 7 instead of 9 thereafter. The measure, approved by the Players' Council, responds to players blaming balls for the rise in wrist, elbow and shoulder injuries.

Novak Djokovic confirmed at Wimbledon: "The quality of the balls changed after the pandemic".
