“It isn’t a good sign for tennis, in general,” said Alcaraz about WADA’s appeal to the Court of Arbitration for Sport (CAS), after his 6-1, 6-2 win against Tallon Griekspoor at the China Open. “It seemed like the case was close, and now, after a month, it’s open again, which is surprising,” he added.

Carlos Alcaraz says he sympathises with rival Jannik Sinner over the reopening of his doping case, and thinks it is “not a good sign for tennis”.

Top-ranked tennis player Jannik Sinner said he was "very disappointed and also surprised" after a decision to clear him of wrongdoing following two positive drug tests was appealed by the World Anti-Doping Agency.

World No. 1 Jannik Sinner responded to the World Anti-Doping Agency's (WADA) appeal to CAS (Court of Arbitration for Sport) seeking a 2-year ban on him.
