Nick Kyrgios advances to the Wimbledon semifinals for the first time, a day after facing assault allegation from an ex-girlfriend

• Nick Kyrgios advanced to the Wimbledon semifinals on Wednesday, after beating Chile's Cristian Garin.
• The win came a day after Australian media reported on an assault claim against the tennis star.

Nick Kyrgios beat Chile's Cristian Garin in straight sets on Wednesday to advance to the Wimbledon semifinals for the first time, a day after Australian media reported that the tennis star was facing an assault claim back home.

On Tuesday, The Canberra Times reported that Kyrgios was due in court next month to face an allegation that he grabbed his ex-girlfriend, Chiara Passari, in December 2021.

Passari spoke out about the timing of the claim on social media Tuesday, insinuating that it was only a coincidence that the claim made the news the day before her ex's big match. Wednesday's win marks the first time that Kyrgios, the world No. 40 men's player, has made it as far as the semifinals of any Grand Slam singles tournament.

Responding to a comment of support on her Instagram, Passari wrote, "Thank you. Finally someone smart enough to understand how the justice system works," news.com.au reported.

Kyrgios and Passari dated for 18 months before breaking up after police were called to intervene in a verbal altercation in October 2021, The Daily Telegraph reported in December.

Passari told the newspaper that Kyrgios was "manipulative" and gaslighted her. Their breakup argument came after she publicly accused him of cheating on her in an Instagram post.

Kyrgios is now dating influencer Costeen Hatzi, who showed up to Wimbledon holding his hand Wednesday morning, and supported him at Centre Court in his match against Garin.

ACT Policing confirmed to Insider on Tuesday that a 27-year-old Watson man is scheduled to appear in the ACT Magistrates Court on August 2 "in relation to one charge of common assault following an incident in December 2021." But the police statement did not mention Kyrgios by name.

After multiple outlets reported that Kyrgios had been charged with assault, legal representatives for the tennis player released a statement saying he had not been charged yet.

"At the present time, the allegation are not considered as fact by the Court, and Mr. Kyrgios is not considered charged with an offense until the First Appearance," the statement from Johannessen Legal read.

"Until the Court formally accepts the Prosecution will be proceeding with a charge, and that the charge before the Court is to be applied to the person summoned to appear, it may be misleading to the public to describe the Summons in any other manner than a formal direction to appear to face allegations, the precise nature of which is neither certain at this moment nor confirmed by either the Prosecution or Mr. Kyrgios.

"While Mr. Kyrgios is committed to addressing any and all allegations once clear, taking the matter seriously does not warrant any misreading of the process Mr. Kyrgios is required to follow."

Neither representatives for Kyrgios nor Passari responded to Insider's requests for comment on Tuesday and Wednesday.

Kyrgios is known for his fiery behavior on the court. He has been fined $14,000 for his behavior at Wimbledon so far this year — more than any other player — for spitting at a spectator in his first-round match and saying an obscenity during his third-round match, according to CNN.
