Aryna Sabalenka took to X today to show how a Dunlop type of ball looks after 25 minutes of use and it's needless to say that the ball in the picture looks completely worn out.

Fritz, the world number four who was the top seed in Texas, lost to Canada's Denis Shapovalov 2-6 6-3 7-6 (7-2).

The Canadian’s 2-6, 6-3, 7-6 (2) victory over the No. 4-ranked American was his biggest win by ranking since 2022.

A day of misery unfolded for US men's tennis as Ben Shelton, Taylor Fritz and Frances Tiafoe all suffered defeats at the 2025 Dallas Open.

Fritz is far from the only player on the ATP Tour who is unhappy with the quality of tennis balls over the past few years.
