No action against Zverev
Former world No.2 Alexander Zverev will face no disciplinary action from the ATP after an independent investigation found "insufficient evidence" to substantiate allegations of domestic abuse, it was announced yesterday.
The German player became the subject of an ATP-commissioned probe in October 2021 following allegations made by his former girlfriend Olya Sharypova. Zverev had denied all of the allegations.
The ATP said in a statement: "A major independent investigation into Alexander Zverev has found insufficient evidence ... As a result, no disciplinary action will be taken by ATP."
