Serena Williams says she ‘would be in jail’ if she behaved like Zverev on court

• Williams accuses tennis authorities of double standard'
• Zverev was disqualified for hitting umpire's chair with racket

Serena Williams has accused tennis authorities of double standards, claiming she would probably be in jail" if she behaved like Alexander Zverev, who was thrown out of an ATP event after smashing his racket against the umpire's chair.

Zverev was disqualified from the ATP 500 tournament in Acapulco and fined $40,000 over the incident, in which he came perilously close to hitting the umpire Alessandro Germani. The world No 3 repeatedly struck Germani's chair after losing a first-round doubles match, but is yet to receive any further sanction after issuing an apology.
