Serbia’s world number one Novak Djokovic says one of the reasons he decided to play the US Open was to help the sport “keep going”.
Djokovic, 33, is in New York preparing for the Grand Slam event which takes place from 31 August in New York.
A number of players, including reigning champions Rafael Nadal and Bianca Andreescu, have pulled out because of health and travel fears.
“I felt responsible as a top player to be here,” he told the New York Times.
“It’s important for our sport to keep going.”
